Abstract In order to overcome the disadvantages of the series diode big reverse recovery current and to load parameters matching in the conventional current-source resonant inverter, the paper presents a improved CLC current-source resonant inverter, It realizes the zero-voltage and zero-current switching of the main switches and suppresses surge current through series snubber inductances and parallel gate-drain capacitances. Changing the power devices switching frequency and matching the load capacitance parameters, the output current and the load branch current are considered to set the small capacitive operation range and the maximum output active power. The experiments demonstrate the correct of the improved topology and the validity of the quantitative analysis.
