要約(英語): In this study, we considered a stray-capacitance charge recovery circuit to reduce the switching loss of a high-voltage high-frequency inverter. The recovery circuit causes the reactor and stray capacitance to resonate to reduce the stray-capacitance charging voltage. This loss can be reduced by switching the MOSFET of the inverter when the voltage drops. In this paper, we first study the stray capacitance of the gate transformer, which is the cause of the loss increase. We then explain the circuit configuration and operation of the circuit that recovers this stray-capacitance charge. Next, the simulation results of the circuit operation are presented. Finally, according to the results from a prototype test, we show that it is possible to reduce the loss of the inverter main circuit and double the repetition frequency with respect to the conventional approach.
