In recent years, high frequency inverter technology has become a research focus for renewableenergy power generation system. High frequency isolated inverter has electrical isolation, light weight,small volume etc. In this paper, we research on the control technology of high frequency isolationinverter, and introduce the soft switching technology of the high frequency isolation photovoltaic gridconnected inverter. Using the LCL resonant circuit, reduce the switching loss of the switching devices. Finally, its feasibility is validated by simulation.
