Document Type and Number:
Japanese Patent JP7341359
Kind Code:
B2
Abstract:
A power converter includes a converter circuit, a capacitor, and an inverter circuit. The converter circuit includes diodes that are connected in a half-bridge configuration. An alternating-current input end of the converter circuit is connected to one side of an alternating-current power supply. The inverter circuit includes semiconductor switching elements that are connected in a three-phase bridge configuration. An alternating-current output end of the inverter circuit is connected to a motor as a load, and an alternating-current output end is further connected to another side of the alternating-current power supply.
