Patent ID: 10432106

Abstract:
A power conversion device includes a printed wiring board on which an alternating-current power-supply input part, a converter circuit part to convert alternating-current power to direct-current power, an inverter circuit part to convert direct-current power converted by the converter circuit part to alternating-current power, an alternating-current power-supply output part to output alternating-current power converted by the inverter circuit part, and a conductive pattern to electrically connect the alternating-current power-supply input part, the converter circuit part, the inverter circuit part, and the alternating-current power-supply output part to one another are provided, and a busbar that has a plate-like shape with a plane direction thereof perpendicular to a plane direction of the printed wiring board, is arranged to overlap the conductive pattern in plan view, and includes two or more connecting portions that are in contact with the conductive pattern.
