Abstract: This paper presents a low cost DC-DC converter design for uninterruptible power supply for Mini Telecommunication Tower (MTT) utilizing solar power as its main energy source. The proposed design is based on boost topology switched mode power supply with a simple voltage control mode controller but maintain good efficiency in its operation. This converter is set to operate at high switching frequency in order to produce a decent and high power-to-volume ratio design. Passive low pass filter is implemented to produce a very low ripple output voltage in the design. Experimental results show that the proposed converter interacts very well with the constructed choke design. Output voltage is regulated at 48V and switching frequency is set at 30 kHz to minimize the switching stress and conduction losses. Practical implementation of the converter shows that the converter operates effectively using commercial 18V solar panel and only produces 20mVp-p ripple output voltage which is considered good for a regulated DC output.

Dr. S.Titus, E.P. Sangeetha, R.Ilango

DOI: 10.17148/IJIREEICE.2019.7605

Abstract: This paper proposes a solar PV connected into the single-phase grid connected system with Harmony Search Algorithm (HSA) for tracking the Global maximum peak point. Boost converter is connected to the grid for energy management system. This proposed scheme provides output with improved power quality under the nonlinear load conditions. Program analysis was implemented to find the peak point under various temperature and radiations. The output of the grid voltage and current can be monitored and compared with inverter output. Depends on the change in voltage and current the duty cycle of the dc-dc converter will change by HS algorithm. This proposed work involves PV panels connected in series to track the maximum peak point. The time varying radiation and temperature are fed as the inputs to the PV panel and the normal harmonic search algorithm is used for Maximum Power tracking. It generates a reference PV voltage and from the reference voltage, an optimum duty cycle (β) for the maximum peak is generated. The optimal duty cycle ratio will gives the required output power under nonlinear conditions.

Abstract: As an intention to meet the growing energy demand and to change from all costly fossil fuel sources, many countries have promoted renewable energy source. PV costs are dropping and a lot of attractive projects have resulted throughout the world. Furthermore, the easy and quick implementation of Solar PV gives it a competitive advantage over other renewable energy sources. A MPPT technique is implemented to the system to track the maximum power point of PV. This paper presents a comparative study of seven conventional Maximum Power Point Tracking (MPPT) algorithms. Their performance is evaluated using the simulation tool called Simulink. In particular, this study compares the behaviors of each technique in the presence of solar irradiance. The Results show that Hill Climb, Perturb and Observe and Incremental Conductance generate much more energy under constant condition. And also that the MPPT Constant Current does not vary under the change of irradiation and has a fast response to reach a steady state compared to the other ones.
