Performance Analysis Of Maximum Power Point Tracking Based Photovoltaic Module With Cuk Converter For Electrical Applications

Abstract: In recent days, Photovoltaic power generation systems are becoming increasingly prevalent in distribution and generation systems. Many industrialized nations are installing significant solar power capacity in their grids as a supplement or alternative to other power sources. This project presents an MPPT based PV module with CUK converter for electrical applications. In conventional system, high ratio DC-DC converter is having high switching loss due to extreme duty ratios and numerous turns’ ratios in the coupled inductor. Also the converter used is single stage, having low power. Also the DC-DC converter used is the boost converter, whose voltage gain is comparatively lower. It also possess severe diode reverse recovery problem. If high duty cycle is used for getting high output voltage, will lead to poor dynamic responses. To overcome these difficulties and to use in application level CUK converter with a PWM inverter is used. In the proposed method, instead of using the boost converter, the CUK converter with a PWM inverter is used. The PWM inverter uses a filter to reduce the harmonics .The PV model also uses MPPT to track maximum power from the panel.
