Abstract: This paper deals with the design, analysis and comparison of power electronic converter that suits the best for photovoltaic system. Renewable energy has become the center of rising interest now-a-days. They are the sustainable energy sources that come from the natural environment. It is a clean alternative to fossil fuels. Therefore, power electronics application to field such as photovoltaic generation, wind power generation etc. has become vital. Converters and inverters are used so that the generation using these renewable resources is carried out easily and efficiently. This project deals with the comparison of design, modeling, simulation and implementation of DC to DC converters used for photovoltaic. The performance of the system in terms of Total harmonic distortions and efficiency of the output produced by the converter are compared by using various converter topologies namely, buck-boost converter, Cuk converter and Sepic converter. By choosing the best efficient and ripple-free converter, the need of filter circuits can be reduced or eliminated significantly. Based on the total harmonic distortion and efficiency, the best suitable converter for the photovoltaic is concluded. A photovoltaic panel rated 24v delivers 250W Power, with a switching frequency of 20 KHz for the converters.
Keywords: Power Electronic Converters, Photovoltaic, Total Harmonic Distortion, Efficiency.
