Abstract

A kind of power conversion apparatus mainly connects the first and the second self-dispersed arc semiconductor elements as the bridge structure at the main power port. It is characterized in that between one port of the bridge and the connection point of the self-dispersed arc semiconductor element there are at least two capacitors series-wound; and on one side of the capacitors which are shunt winding and switch from discharging to charging status, at the time that the switch component will change from nonconductive mode to conductive mode, the capacitor on the other side is connected to both ends of the bridge by resistor architecture.
