Design and development of DC-DC buck converter for photovoltaic application

This paper presents the design and development of DC-DC buck converter for photovoltaic application. The intention in designing DC-DC buck converter is to provide robust and high performance power point tracker acting as an intermediate between supply source and load. The system was simulated using Power Electronic Simulation (PSIM 9.0). The procedure in terms of selection of components has also been demonstrated. The experimental results show that with a constant input voltage of 80V, the buck converter is able to produce 164W with average 60 percent efficiency.
