This paper proposes a high-speed switching method of MOSFETs applied to a high-frequency half-bridge inverter. The turn-off time of the MOSFETs can be shortened by employing a set of auxiliary switches in parallel with a load; this reduces switching loss of the MOSFETs. It was confirmed through experimental tests that the total efficiency of the inverter was improved by the proposed method, particularly in a low-load range.
