Abstract: The power generation using Photovoltaic (PV) cell is the best alternative developing for fossil fuel since it does not have pollution issues. This paper focuses on performance of Cuk and Single Ended Primary Inductance Current (SEPIC) converter, used in MPPT based PV system. Perturb and Observe (P&O) Technique used to generate duty cycle of converters. The simulation is carried out using MATLAB/Simulink and it has been observed that the SEPIC converter produces better result compared to the Cuk converter.

Keywords: Maximum Power Point Tracking (MPPT), Perturb and Observe (P&O), Cuk Converter, SEPIC Converter.
