Abstract : The solar pv based power generation system shows tremendous growth in the present scenario when compared to other renewable energy based power generation. The focus of researchers in this area was increased in recent years. The output voltage in solar cell is of low range and to improve that DC/DC converters are used. This paper focuses to design and analyze the performance of boost and SEPIC DC/DC converter, used in MPPT based PV system. Perturb and Observe (P&O) technique used to generate duty cycle of converters under different irradiance changing condition. The study is performed using MATLAB/Simulink for the PV system and it has been observed that the SEPIC produces better results compared with boost converter.
