ABSTRACT:
A power semiconductor module in which a plurality of power semiconductor elements forming a bridge circuit are provided together with control circuits. The module includes a common casing which accommodates a metal base, a main circuit section, and a control circuit section. The main circuit section has a plurality of semiconductor elements of the bridge circuit mounted on a ceramic insulating board which is thermally coupled to the metal base. The main circuit section also supports connecting conductors to which the semiconductor elements are connected. In the control circuit section are mounted control circuits for the semiconductor elements. The control circuits are mounted on a wiring substrate which is formed by wiring conductors on an insulating board. The main circuit section is connected through a bond to the control circuit section. Input and output terminals of the bridge circuit are extended from the connecting conductors of the main circuit section. Connecting terminals of the control circuits, which are to connected to external equipment, extend from the wiring conductors.
