Research on photovoltaic power generation system based on power electronics

This paper introduces the DC power obtained from photovoltaic power generation, and then boosts it by the boost chopper circuit. Finally, it is inverted by a single-phase full-bridge inverter circuit into 220V, 50Hz single-phase AC power that meets the normal working requirements of household appliances. Give the load. Among them, the inverter is the most important part, which can convert direct current into alternating current. Before this, it is necessary to increase the DC voltage through a boost chopper circuit and then invert it.
