Abstract: Solar energy is most popular amongst the renewable energy sources. The reason being, the solar panels are modular in nature, has long life with non-moving parts and the time for commissioning is less compared to other sources. Like other renewable energy sources it is intermittent in nature and the output power induced in the photovoltaic modules is influenced by the intensity of solar radiation and temperature of solar cells. It is necessary to track the maximum power point of the input source. In this paper, a maximum power point tracker(MPPT) using perturb and observe algorithm is proposed to improve energy conversion efficiency with boost converter. The system is consisting of solar module, boost converter and resistive load simulated using PSIM software.

Keywords: photovoltaic (PV) system; maximum power point tracking system (MPPT); perturb and observe algorithm (P&O); PSIM; Boost converter.
