Patent ID: 10615156

Abstract:
A power module includes: a first conductive plate (23u, 23v, 23w) on which first switching devices (29u, 29v, 29w) and first rectifying devices (20c) are mounted, the first conductive plate having an alternating-current terminal (100u, 100v, 100w) for alternating-current electrical power; a second conductive plate (23a) on which second switching devices (28u, 28v, 28w) and second rectifying devices (20c) are mounted, the second conductive plate having a direct-current positive electrode terminal (120a) for direct-current electric power; and a third conductive plate (23b) connected to the first switching devices and the first rectifying devices, the third conductive plate having a direct-current negative electrode terminal for direct-current electric power, wherein a first direction in which a plurality of the first switching devices are arranged is perpendicular to a second direction in which a plurality of the first rectifying devices are arranged, and the alternating-current terminal extends in the second direction from a position where the first rectifying devices are arranged.
