Abstract
Semiconductor apparatus for mounting and cooling disc type semiconductor devices. The apparatus includes two disc type semiconductor devices each having a pole face thereof in contact with a first terminal bar, that bar in turn being in contact, through thermally conductive electrical insulation, with a water-cooled plate. The opposite pole face of each disc device is in electrical and thermal contact with a first surface of a respective metallic block. A second surface of each block, opposing the first face, is in electrical conductive contact with a second terminal bar. A compressive mounting force is applied across the first and second terminal bars to appropriately compress the disc devices. Each metallic block is sized to absorb a substantial portion of the disc device junction heat generated during a transient portion of a duty cycle, such as may correspond to the starting of a motor.
