Abstract: Photovoltaic (PV) energy is the most important energy resource since it is clean, pollution free, and inexhaustible. The studies on the photovoltaic system are extensively increasing because of a large, secure, essentially exhaustible and broadly available resource as a future energy supply. Due to rapid growth in the semiconductor and power electronics techniques, it is important to operate PV energy conversion systems near the maximum power point to increase the output efficiency of PV systems. The output of PV is given to flyback converter to boost the voltage and to drive a resistive load or incandescent bulb of 40W, inductive load and motor load.

Keywords: Photovoltaic system, flyback converter, Maximum power point tracking (MPPT).
