ABSTRACT:
Technology leading to a size reduction in a power conversion apparatus comprising a cooling function and technology relating to enhancing productivity and enhancing reliability necessary for commercial production are provided. Series circuits comprising an upper arm and lower arm of an inverter circuit are built in a single semiconductor module500. The semiconductor module has cooling metal on two sides. An upper arm semiconductor chip and lower arm semiconductor chip are wedged between the cooling metals. The semiconductor module is inserted inside a channel case main unit214. A DC positive electrode terminal532, a DC negative electrode terminal572, and an alternating current terminal582of a semiconductor chip are disposed in the semiconductor module. The DC terminals532and572are electrically connected with a terminal of a capacitor module. The alternating current terminal582is electrically connected with a motor generator via an AC connector.
