Series resonant inverter with resonance pole capacitor buffer’s process of changing current: Routine RCVD buffer circuit adopts resistor to discharge, with the increase of switch frequency, the power consume in buffer is increase too, greatly reduce the efficiency of the whole inverter system. It can effectively reduce the shutoff loss of switch device that directly parallel connect a non-loss buffer capacitor between IGBT collector and emitter. It is more fit for high frequency inverter to feedback the power of the resistor loss in routine buffer to load or power supply.
