Performance Analysis of Solar Photovoltaic Module using Buck Boost Converter and Zeta Converter

This paper compares the performance of buck-boost and zeta converter fed solar photovoltaic module. The study is carried out by considering a solar pv module, dc-dc converter, MPPT controller and a resistive load. The voltage gain, output voltage ripple and output current ripple of the two converters were compared. Maximum Power Point tracking is implemented and and ensures the extraction of maximum power from the solar panel. Here MPPT is achieved by using perturbation and observation method. Zeta converter topology provides a non inverted output voltage with increased voltage gain. Output has lesser voltage and current ripple compared to buck-boost converter. Photovoltaic module with Buck-Boost and Zeta converter are simulated using MATAB Simulink software and the result are shown.
