The renewable energy source that is now expanding the fastest is solar energy. It is expanding quickly because of its many applications and affordable upkeep. In order to maintain a consistent output voltage, the DC-DC power electronic converter is integrated with the solar PV system. This study examines SEPIC and ZETA converters in conjunction with a solar PV array. In this study, many characteristics like DC voltage, inductance, capacitance, and voltage are discussed. This research also compares and contrasts the SEPIC and ZETA converters. The MATLAB/Simulink environment is used for all work. When all the parameters are set to certain standard values, waveforms are produced. This demonstrates how changing a few parameters could produce distinct waveforms.
