A novel inverter with an improved turn-on and turn-off snubber circuit is proposed, which can suppress the maximum voltage applied on the main switches of the circuit. No additional sensor is required for control. Mitigation of the maximum voltage of the main switches and soft-switching are confirmed through circuit simulation and experiment with a 1kVA circuit. Reduction of switching losses is confirmed by experiment. Improvement of inverter loss is shown by estimation of losses of high power circuit based on experimental results.
