Research on Single Phase Photovoltaic Generation under Grid-Connected Inverter

The grid-connected photovoltaic system is a trend of photovoltaic system development. According to the character of solar array,we designed a novel grid-connected photovoltaic inverter with the function of Maximum Power Point Tracking.The inverter consist s of a DC-DC converter and a DC-AC inverter and the two parts are combined by a Dclink. The part of control achieve synchronization sinusoidal current output with the network voltage.
