A Single Stage Transformerless Inverter Topology With MPPT for PV Systems
Anchu B S , Arun Kishore W. C
Abstract: The commonly observed trend in photovoltaic (PV) inverter technology is the usage oftransformerless topologies in order to acquire higher efficiencies combining with very low ground leakage current. Usually converter topologies such as buck, boost, buck-boost, sepic, flyback, push pull etc. are used in a Grid Connected Photo-voltaic System (GCPVS). Loss factors such as irradiance, temperature, shading effects etc. have zero loss in a two stage system, but additional converter used will lead to an extra loss which makes the single stage system more efficient when compared to a two stage systems. In this paper a new inverter topology for single stage PV system is proposed. The proposed inverter is synthesized from an inverting and non-inverting Cuk inverter where the diodes are replaced with controllable switches. Here the number of switches are reduced thereby minimizing the switching losses. Sliding Mode Controlled (SMC) maximum power point tracking method is used here. The sliding mode controller is given the estimated maximum power point as a reference which enables it to track that point and force the PV system to operate in this point. The proposed inverter topology for an 80W system was designed and simulation was done in MATLAB- Simulinkand the simulation results are included.

Grid-Tied PV System with Small DC-Link Capacitor and Low-Frequency Ripple-Free Maximum Power Point Tracking
Archa Das, Raji Krishna, Lekshmisree V
Abstract: This paper proposes a grid-tied cascaded multilevel inverter (CMI) PV system based on current-fed dual- active-bridge (CF-DAB) dc-dc converters using small dc-link capacitors. The cascaded multilevel inverter (CMI) has many advantages, such as modularity, low harmonic spectra, high ac voltage application with low device rating and low electro-magnetic interference (EMI). In addition, distributed maximum power point tracking (MPPT) terminal for segmented PV arrays can be achieved by CMI PV converter. The low-frequency ripple-free MPPT is also realized in the proposed converter. A novel variable step-size MPPT algorithm is proposed to ensure high MPPT efficiency and fast maximum power extraction under rapid irradiation change. Fast tracking speed under rapid irradiation change and high MPPT efficiency were realized for the PV system.

PV Integration to DC Micro grid using Modified Converter Topology
Priya Philip, Shaini A.P
Abstract: The usage of photovoltaic for solar energy conversion is a rapidly growing source of green power supply. Enhancing the efficiency of this system is widely seen as important in supporting this trend. This concerns not only the improvement of the PV cell but also of the power electronics circuits and controls associated to them. The various difficulties identified for the development of such a system is that discontinuous mode of conduction must be avoided and ripple content must be reduced. Therefore, in order to achieve this, an interleaved boost converter with maximum power point tracking based irradiance adaptive control is developed.

Analysis and Control of Commutation Errors in Sensorless Drive of BLDC based on Compensation Techniques
Megha S Pillai, Vijina K, Meera Murali
Abstract: Brushless dc motor has permanent magnets which rotate around fixed armature. The current in armature rotates as it is electronically commutated. The commutation angle errors reduce the performance and overall efficiency of the motor. The novelty of the work is reducing commutation errors that are obtained based on the relationship between commutation point phase shift and the difference of dc-link current. Based on these relationship analysis is made under ideal, advanced and delayed commutations. The self-compensation method of commutation instant deviation delays the commutation angle by 10º thus eliminating the impact caused by commutation ripple thereby improving dynamic performance and control. The dc-link current difference decrease gradually and phase deviation converges to adjust the commutation angle. The proposed correction method can achieve ideal commutation effect thereby attaining fast convergence speed, current and torque.

Kavya Suresh, Nandan.G
Abstract: Electric power produced by the use of ordinary fuels will produce toxic gasses like carbon dioxide, carbon monoxide, nitrogen dioxide etc. Which will causes environment contamination and as a result cause to global warming. This bring to the use of renewable energy sources. A Solar Photovoltaic (SPV) system, along with Maximum Power Point Tracking (MPPT), catenated to a three phase grid which feeding a switched reluctance motor is introduced. The catenation of solar photovoltaic system to the grid arise through two stages of operations, which is through a DC/DC boost converter via a current controlled Voltage Source Inverter (VSI). The Maximum power point tracking algorithm used is Perturb & Observe (P &O) algorithm, which is applied to the boost converter. Also reference reimbursement current has been generated by using I cos Φ algorithm. Adaptive hysteresis band current controller is used for switching pulse generation in current controlled VSI.

Riya Anna Thomas, Reema N, Dhanusha T
Abstract: Induction motors are the widely used machines in many industrial applications. But the induction motors results in high starting current, occurrence of common mode voltages, difficult to control etc. This work proposes controlling of a dual inverter fed induction motor with open end stator windings. The three level dual inverter received large attention due to its simplicity and it reduces the voltage rating of the semiconductor devices which further reduces cost of the system. This system is operated using an integrated control which includes maximum power point tracking and space vector pulse width modulation technique. A boosting converter with a high voltage gain is also used which requires no chemical storage elements such as batteries and make the system more effective. For tracking the maximum power Perturb and observe method is used. Space vector modulation is designed such that it eliminates the common mode voltages generated and has less distortions compared to the conventional methods. The modeling of dual inverter fed open end winding induction motor, conventional induction machine, PV system, MPPT algorithm, Dickson charge pump and switching of inverters using space vector modulation has been done and the output waveforms obtained are analyzed.

Vishnu P V, Vishnu J
Abstract: The static pollution-free Photovoltaic (PV) Cells are considered as one of the most important and promising type of renewable energy systems. Photovoltaic power generation is however possible only on a sunny day, and there is complete absence of power on a cloudy day .The suggested solution to this problem is a hybrid system. Hybrid systems such as Solar-Wind, Solar-Wind-Fuel Cell Hybrid systems etc are defined as energy systems combining two or more complementary power generation devices where the best features of each source is captured. A Novel Stand-Alone Photovoltaic –Synchronous Generator Hybrid system is proposed here, in which the Maximum Power Point of the PV generator is tracked, and is used to control the AVR of the Synchronous Generator .This AVR is now used to control the Voltage of the common coupling point of the Synchronous Generator and the PV Generator Thus the voltage of the PCC will be the voltage corresponding to the MPP. A Power control unit is incorporated to control the driving torque of the synchronous generator once the PV generator becomes unable to meet the requirements of the motor because of reduction of the solar irradiance and/or increase of the load.

Gayathri Vijayan, Raji Krishna, Anumol George
Abstract: The current source flyback micro inverter plays a vital role in PV applications. Presently central inverter system is replaced by micro inverter. Micro inverters are small inverters rated to handle the output of a single panel. Many converter topologies have been proposed for the AC-PV modules. Among those, the fly back inverter has been the center of attention because it satisfies the application requirements such as high voltage step-up ratio, galvanic isolation, low volume, high reliability, and provides high efficiency and relatively simple control. This paper proposes an efficient fly back inverter with mppt control. The center tapped transformer is replaced by a two winding transformer to decrease the current losses. Fly back inverter has three modes of operation. They are DCM (Discontinuous conduction mode), BCM(Boundary conduction mode) and CCM (Continuous conduction mode).By using mppt control we can avoid the problems of individual conduction modes. The performance of the proposed model is simulated in MATLAB/ Simulink environment.

Surya R Chandran, K L Sreekumar
Abstract: As far as renewable energy is concerned solar photovoltaic means of energy production plays a major role. Since sun’s energy is available in abundant not completely its source is utilized by the photovoltaic cells. So, efficiency of the energy conversion scheme should be high. Hence a high-efficiency dc–dc converter is proposed for low-voltage photovoltaic sources. The proposed converter boosts up the DC voltage with high voltage gain and high efficiency. The proposed converter uses a transformer-less adjustable voltage quadrupler dc–dc converter with high-voltage transfer gain and reduced semiconductor voltage stress is proposed with an input-parallel output-series configuration for providing a much higher voltage gain without adopting an extreme large duty cycle.

SIMULATION AND ANALYSIS OF SINGLE STAGE SOLAR PV FED BRUSHLESS DC MOTOR FOR WATER PUMPING
Mumthas A, Johnson Mathew
Abstract: The global energy crisis in near future due to the rapid depletion of conventional fossil fuel resources and a consistently diminishing costs of solar photovoltaic (PV)modules, motivate towards an effective utilization of solar PV technology. In order to optimize the solar photovoltaic (PV) generated power using a maximum power point tracking (MPPT) technique, a DC-DC conversion stage is usually required in solar PV fed water pumping which is driven by a brushless DC (BLDC) motor. This power conversion stage leads to an increased cost, size, complexity and reduced efficiency. Here addresses a single stage solar PV energy conversion system feeding a BLDC motor-pump, which eliminates the DC-DC conversion stage. In addition, it constitutes the attractive merits of conventional topology , such as the elimination of BLDC motor phase current sensing and soft starting. The suitability of proposed system is validated through its performance and evaluation using MATLAB/Simulink based simulated results.

A New Approach For The Current And Torque Ripple Minimization Of BLDC Motor Using Phase Voltage Method
Meera Murali, Sreekanth P. K, Megha S Pillai
Abstract: This paper introduce a novel sensorless control for the Brushless DC motor drive by phase voltage method for minimizing the torque and current ripple in high speed, high power applications. The commutation signals for the six switch inverter are generated from the phase voltage. In each phase commutation two switches conduct corresponding to the truth table logic. Delay occurring in speed is compensated by the phase voltage deviation. Selection of commutation logic in a parallel mode improves the efficiency of system by reducing the operation delay. Compared with the existing traditional control torque and current ripple of BLDC motor can be significantly reduced by using this proposed method.

Modified P&O Based Mppt Controller For Photo Voltaic System Under Partial Shading Condition
Padmajan V, Sony M G
Abstract: It is essential to extract the maximum available power from solar system since the energy efficiency of solar cell is about 13%-17% only. There must be converter for efficient electrical tracking. It is achieved by impedance matching between load and solar module. There may be multiple peaks under varying illumination and under partial shading of individual modules. In these case we have to track global maximum power point (GMPP) apart from local maximum power point (LMPP). The conventional techniques either cause energy wastage due to unwanted full PV curve sweeping or complex due to photo sensor and error in calculation. So a new algorithm based on modification of conventional P&O algorithm to track GMPP is trying to establish

A Novel Method for Torque Ripple Minimization of PMSM Using a New Proportional Resonant Controller
Karthika S, Saleena Mary George
Abstract: The minimization of speed ripple of the permanent magnet synchronous motors (PMSM) in low speed range becomes a major problem while applying the PMSM to refrigerant system. In conventional methods, an iterative learning controller is applied in conjunction with the conventional proportional integral (PI) speed controller to minimize the speed ripple. In this paper a frequency variable resonance controller is applied with the conventional proportional integral speed controller as a PI-RES controller, which provides the reference torque current. The main reference current generated by the PI controller together with the compensation torque current generated by the resonant controller is used to minimize speed ripple. The proposed method is verified through simulation results.

Enhancement of Efficiency of Air Conditioner Using Switched Reluctance Motor
Rahul M, Sindhu. V
Abstract: In the conventional air conditioning system, induction motors are used for driving the compressor. The main problem of AC(Alternating current) supply while using an inductive load is low power factor, presence of plentiful harmonics at the ac input side and it requires high starting current. Here the induction motor is replaced with an SRM (Switched reluctance motor), and thus the system can be used for low power solar applications. The efficiency of a switched reluctance motor is more compared to a conventional induction motor. In air conditioning system, using inverter technology as drive circuit for induction motor, DC is obtained at the second stage of the inverter circuit. This DC supply can be used to drive the Switched reluctance motor and thus the cost of additional drive circuit can be compensated. SRM has relatively high starting torque compared to induction motor with minimum starting current, which makes it more suitable for air conditioning system, which further enhances the power quality for the power distribution system. Further, the SRM can be used in places where DC grid exists, i.e. in a train. Conventionally, induction motors are used in a train to drive its air conditioning system. And the DC supply is inverted and fed to the induction motor. Replacing induction motor with Switched reluctance motor in air conditioning system of train will improve the overall efficiency of the system and thus reduce the running cost. Life expectancy of a SRM is comparable to that of an induction motor. So, SRM can be used in place of induction motor in these applications.

Electric Vehicle Control using PMSM
R Reshma, Vishnu J, Bijimol P S
Abstract: Considering model parameter imbalance and one-step lag, an revised Deadbeat Predictive Current Control (DPCC) is proposed in this work. It improves the performance of current control of Permanent Magnet Synchronous Motor (PMSM). By improving the current control, losses in the machine can be reduced and machine performance can be improved. For doing this, traditional predictive current control performance is analyzed. Based on sliding mode exponential reaching law, a stator current and disturbance observer (SCDO) is being proposed. SCDO can concurrently forecast future value of stator value of stator current and track system disturbance caused by parameter imbalance. For compensating the voltage reference calculated by deadbeat predictive current controller, a feed forward value is considered. This feed forward value is the prediction currents based on SCDO. These are used for replacing the fragmented current in DPCC. By connecting the DPCC part and current forecasting and feed forward rectification part based on SCDO, a compound control method is developed in this work. This paper focuses an adaptive SCDO based on novel adaptive sliding mode reaching law which can increase the control performance of the existing method. This method can be used for Electric Vehicle (EV) control.

Speed Control of PMSM Drive Using Adaptive Fuzzy Logic Controller
Vishnu Mahesh J, Sreelekha V
Abstract: Permanent Magnet Synchronous Motors (PMSM) are widely used in low and mid power applications such as computer peripheral equipment, robotics, adjustable speed drives and electric vehicles. The growth in the market of Permanent Magnet motor drives has demanded the need of simulation tools capable of handling motor drive simulations. Simulations have helped the process of developing new systems including motor drives, by reducing cost and time. In a closed loop system the speed of a Permanent Magnet Synchronous Motor can be controlled by measuring the actual speed of the motor. PI (Proportional Integral),PID (Proportional Integral Derivative) and Fuzzy controllers are commonly used for the speed control. In this paper the speed responses of a PMSM is obtained using adaptive fuzzy PID controller.

DHANUSHA T, GAYATHRI VIJAYACHANDRAN, RIYA ANNA THOMAS
Abstract: Nowaday, model predictive based torque control is arise as one of the powerful control technique for the IM drives. The fast response and accuracy is the main features of predictive torque control technique. The control technique includes the predictive controller to obtain better dynamic response and PI controller to attain better steady state response. The main characteristics of PTC is by using the machine model for determining the future performance of the variables which is to be controlled. In MPTC scheme, the command signals are indicated as cost function, which is to be reduced. It has increased resilience to use constraints that gives low computational complexity compared to simple vector controlled schemes. PTC offers increased dynamic behaviour and improved speed responses. A modified MPTC is sugested for the control of the torque ripple minimization. A portion of time interval is given to the non zero voltage vector, while the remaining time is given for a zero vector. The minimisation of torque ripple concept help to know the time period for individual vectors. The proposed method proves that it gives excellent steady state response by the reduction of the torque ripples.

Jisha Anna Mathew, Juna John Daniel, Najma Habeeb
Abstract: Solar power used is the best alternatives. It produces electrical energy which is low cost and efficient, used in pumping application which is simple, robust. The innovation of the work is to implement Perturb and observe algorithm based Maximum Power Point Tracker (MPPT) to boost the systems capability. A PV array is proposed for extracting power and in between the SRM drive and PV array a zeta converter is provided for continuous operation of MPPT thereby shrinking the amount of sudden current flow to the system. An SRM uses a spilt phase capacitor drive for providing the required voltage pulses for phase windings excitation in all of the four phases in SRM. A zeta converter is also proposed as it does not need any additional circuit to limit the sudden flow of current to the system. The SRM drive is controlled with variable DC link voltage of spilt phase converter and it depends upon the different environmental conditions and irradiance level of SPV array. The obtained results have shown that the efficiency of the proposed system is better at higher irradiance levels.

Najma Habeeb, Juna John Daniel
Abstract: A Switched Reluctance Motor (SRM) drive has wide benefits such as high torque-volume ratio, low manufacturing cost, high dynamic response and wide speed range is required. Many industrial and home appliances have devices of power automatic recycled as a rectifier and driver along with motors. The use of these devices have several non-linearity in the electrical system. Some problems are high harmonics, low power factor, reduced performance and increased consumer cost has produced as a result of non-linearity. In a conventional switched reluctance motor drive, the AC mains power factor is low and the overall Total Harmonic Distortion (THD) rises as a result of harmonics. In instruction to diminish the THD and progress the power factor of the supply mains of SRM, a Bridgeless canonical switching cell (CSC) converter configuration is working in Discontinuous inductor current mode and it is recycled to control the yield voltage of DC and to enhance the power factor at the supply mains. Furthermore, it controls the voltage of DC-link and to find the speed controller of motor side. Here, the SRM with diode bridge rectifier (DBR) and also, with and without converter is analysed. The THD and power factor of the above systems was analysed. The power quality directories are obtained in the array of International power quality principles like IEC 61000-3-2. The drive performance is evaluated by using MATLAB/SIMULINK software.

High Precision Sensorless Control of BLDC Motor with Z-Source Inverter
Soumi A, Prince A
Abstract: Brushless dc motors are getting more attention in many areas owing to its compactness, maintenance, high efficiency and low cost. Precise detection of rotor position is essential to achieve high efficiency. Mechanical sensor based methods increase size and inaccuracy. Back EMF method is one of the most popular control method for sensorless brushless dc motor. But this method is not suitable for high-speed operation, for the pulse width of zero- vector may be very short. Z-source inverter based approach to zero-crossing point detections during the shoot-through vectors for sensorless brushless dc motor is discussed here. This approach separates the zero crossing point detections from speed adjustment, and makes the shoot-through vector not influence the motor speed-adjustment directly. With this approach, the sensorless drive can operate in a wide speed range. It not only provides boost voltage for sensorless brushless dc motor drive system, but also improves the utilization rate of dc source voltage and the safety of the drive system.

A Robotic Crack Detection System for Bridge Maintenance
Archa A B, Arsha Jayachandran, Arya S, Athira Ajayan
Abstract: Nowadays, crack detection has become an important necessity for the maintenance of bridge. Earlier, bridges were inspected by a method of human inspection, which had less accuracy in finding out the presence of cracks. So here a system is proposed that uses a robot equipped with a camera that captures images of crack. This images are evaluated using image processing techniques and finally cracks are been identified using edge detection procedures. Mainly canny algorithm is used for the purpose of detecting cracks. When a crack is detected messages are sent to the concerned authority with the help of GSM. This system thus works effectively as a safety system for bridge deck maintenance.

Minimisation of Torque Ripple in PMSM Using a Proportional Resonant Control Technique
Bijimol P S, Sheleel F, Anagha Basheer
Abstract: Permanent magnet synchronous motors (PMSM) are extensively used in many applications including robotics, precision machining etc. because of their good features such as, high efficiency, light weight, better accuracy, and low maintenance requirements compared to induction motors. Because of the increasing demand for energy efficiency, PMSM replaces the traditional induction motors. The main problem with this motor is the formation of torque ripples at low-speed which may cause mechanical vibrations and induces oscillations in speed. So low-speed applications of this motor have some limitations. Vector controlled PMSM drives can be used to supply lesser torque ripples and better dynamic response. Conventionally Proportional integral (PI) controllers are used for this. But the performances of the PI controllers are affected by load disturbances, speed variations and parameter variations due to its constant proportional gain and integral time constant. The novelty of this work is implementing a new control technique by using a PI-resonant (PI-RES) controller by paralleling a variable frequency resonance controller with the conventional PI controller.

Abstract: When more than one source is available for a given load, the sources may be utilized in a better manner to supply power efficiently to the load. In this project we consider two sources such as solar panel and wind energy. Both these are renewable energy sources and the production capacity of these depends upon a large number of external features. The project houses a DC bus in which both the powers generated by wind and solar are given to the load. Depending upon the load requirement only solar or the wind can be made to supply power. Using low voltage DC for the NANO grid provides various advantages such as easier integration with renewable sources and battery banks, increased savings, etc.Future systems would use renewable sources and storage devices to become self-sufficient in generation with bare minimum consumption from the grid. The project houses current and voltage sensors for measuring the power output of the solar panel and the wind energy. As the whole process takes place automatically there is a very lesser need for human interference and the electricity losses during the distribution can be saved on a huge scale.

The power demand is increasing and also the management of electric power distribution system is becoming more complex. The effective detection and correction of the faults in distribution side still remains an enigma to the power company. Such situations will lead to power disruption of a wide area. The existing system offers unlimited access to the usage of energy which in turn leads to massive power wastage. The proposed system is useful for facilitating alternative supply to an emergency load from nearby healthy zone. The proposed system also controls demand by shedding loads whenever the load exceeds the peak limit and is also provided with an innovative scheme for theft detection and monitoring of electrical power theft in the electrical distribution system.

Abstract: The Public Distribution System (PDS), established by the Government of India under Ministry of Consumer Affairs, Food, and Public Distribution to distribute grocery items to poor people at fair price is facing significant threats to its very existence. These threats starts from the basic issues of renewing the ration card every year which has to be done manually by the employees to the malpractices done by the ration store dealers like diverting food grains to open market to make profits. There is another problem of irregularity in opening shops and false announcements of deficit in food grains. Hence through this paper the idea is to completely automate the rationing system. For simplicity, it is better to implement an embedded system for the same. In the proposed system, the advanced ARM8 (Advanced RISC Machine) processor is used and it is the heart of the system that controls all sub systems like sensor modules, database systems, connected across it. The user authentication is provided by smart card (RFID card). The Customer/ user can access his/her ration through this diverse smart card.

Face Recognition and Finger Print Based Enhanced Security System for ATM Transaction
Surjith S, Akshaya Mohan Akhila Alexander, Ayana Mohanan
Abstract: Access control has been a great concern in the information and communication era. In this proposed system we try to reinforce the security of conventional ATM models by using password authentication method combined with biometric identification technology. Biometric refers to automatic identification of a person based on his/her physiological characteristics. Biometric introduces its own challenges such as being irreplaceable once compromised. Biometric authentication is achieved by capturing the fingerprint and facial features of the client. Then the system will check for user’s identity. If it finds valid, the ATM machine will ask the customer for 4 digit code. The 4 digit code is automatically generated by the system as OTP which is sent to the customer’s registered mobile number. Here the customer has to enter this code. The system checks for the validity of the code. If it is found valid bank transaction starts and the customer is able to access his account. Provisions are also included for securing the ATM terminal from fire and theft attacks

Waste Incineration and Energy Production
Sheeja Vincent, Alfiya N, Amina Shiroz, Anagha Prakash
Abstract: India generates about 60 million tons of trash everyyear.10 million tons of garbage is generated in just the metropolitan cities! Waste is a major environmental problem in all over the world. With increasing population and advancement in science and technology, natural resources are also exploited. As a developing country, one of the major crisis faced by India is waste management. India generates about60 million tons of waste every year. Increasing population and advancement in science and technology has begun to exploit the natural resources also. Nowadays an emphasis is given on waste management .Rather than managing waste, we should be looking forward for innovative methods to depose and recycle waste. Even though solid waste is being recycled in various methods, organic waste is still a question mark. When organic waste is dumped in landfill, it undergoes anaerobic decomposition and generates methane, which is a 25 times more potent greenhouse gas than carbon dioxide. Our project is simply a implementation of burning organic waste using incinerator and transforming the heat produced into voltage. Conversion of heat to electricity is carried out by thermoelectric generator.

Due to this, waste lies littered in the surroundings, dumped on open lands and becomes a major threat to the environment. So, waste management becomes an important concern for the health and well-being of the society. Segregation makes it possible to reuse and recycle the waste effectively and the economic value of waste is best realized when it is segregated. So, it is very crucial to have some system to manage waste automatically which is currently not here. So, our idea is to make an automatic waste segregator which can identify the different types of waste and put them in different bins accordingly and automatically. This paper proposes a novel method where the provision is given to separate out metallic, non-metallic waste and plastics into respective bins with the help of sensing action of different sensors incorporated along the conveyor belt. Here we are using AVR (Atmega 16) as the main component, to control the entire process with ease and simplicity. The sensing unit consists of IR sensor, a metal sensor and LDR and laser assembly to detect and identify various types of waste. The main architecture of the segregator comprises of three prominent stages. They are the sensing stage, segregation stage and the crushing stage. The IR sensor marks the entry of waste and is also used to check the level of the bin. The piston compresses the plastic so that a single bin can hold up to 2 times more waste than a normal bin. The wastes moving through the conveyor belt will be moved into the different bins by using a flap mechanism. The AVR controls all the activities of sensor and flap mechanism.

Aseena A Megha V, Nadiya Mol S, Raseena Rahim
Abstract: Internet of Things (IoT) is an ecosystem of connected physical objects that are accessible through the internet. IOT devices are used in many application fields which make the users’ day to day life more comfortable. These devices are used to collect temperature, Pulse rate, and sugar level etc., which are used to evaluate the health condition of the patient. Communicating the collected information to the doctor, making accurate decision on the data collected and notifying the patient is the challenging task in the IOT. In this project, An IoT based Patient Health Monitoring System (PHMS) using Arduino is proposed to collect the required parameters and evaluate the data obtained from the sensor devices. PHMS with arduino also gives the notifications to patient with possible precautionary measures to be practiced by them. This system suggests the patient with medical care and next step to be followed in case of critical situation. The combination of IoT with arduino is the new way of introducing Internet of Things in Health care Monitoring system of patients. Arduino Uno board collects data from the sensors and transfer wirelessly to IoT website. The Proposed PHMS system is evaluated for certain parameters like heartbeat, body temperature, blood pressure etc. and the decisions can be made based on the data obtained from IoT website.

Single Stage PV Fed BLDC Motor Water Pumping Application
Abilash R S, Renjith G, Bindu S J, Lijo Julius
Abstract: The growth of the solar industry has expanded the importance of PV system design and its application for more reliable and efficient way. BLDC motor is a better substitute of the DC motor and induction motor for PV fed water pumping. A DC-DC conversion stage is required in PV fed water pumping which is driven by a BLDC, for optimise the power using Maximum Power Point Tracking (MPPT). Cost, size, complexity and efficiency is reduced due to power conversion stage. This paper deals about a single stage PV energy conversion system fed BLDC motor, by omitting DC-DC stage. The PV array is operated at its peak power using a Voltage Source Inverter (VSI) and also battery backup is provided. The implemented control cancelled out the need of BLDC motor phase current sensor. No additional control is involved for soft starting and speed control. Performance is evaluated using MATLAB/Simulink based simulation under various operating conditions.
