Abstract :
In this paper fully integrated single switch DC-DC Buck-Boost Converter is designed and implemented for photovoltaic (PV) applications. Buck-Boost Converter is employed to transform the unregulated DC supply from the PV system to a regulated output voltage. Conventional switching of converters leads to power losses during switching there by reducing the efficiency of the system. In this work Zero Voltage Source (ZVS) based soft switching is employed to buck boost converter without using auxiliary switches. A 200 W prototype model was designed, simulated in PSPICE and realized in hardware. The experimental results were found to be satisfactory.
