Patent ID: 6843335

Claim:
A power conversion apparatus comprising a power module part having semiconductor elements for power control, and a control part for controlling the operation of the semiconductor elements, characterized in that the power module part includes two substrates mounted thereon the semiconductor elements, an output terminal adapted to be fed therethrough with an electric power controlled by the semiconductor elements and electrically connected to the semiconductor elements, an input terminal adapted to feed an electric power therethrough to the semiconductor elements so as to be controlled by the semiconductor elements and electrically connected to the semiconductor elements and composed of a positive side conductor and a negative side conductor which are laminated with each other being electrically insulate from each other, and a container for accommodating the two substrates, the output terminal and input terminal, at least in part, and the two substrates, the output terminal and the input terminal are arranged in the container so that the output terminal and the input terminal are opposed respectively to the two substrates in two different directions on the respective conductor surfaces of the output terminal and the input terminal.
