ABSTRACT:
A multiphase inverter has two card shaped arm modules facing each other along a stacking direction. Each module has semiconductor switching elements disposed along an element arranging direction substantially perpendicular to the stacking direction, a common heat sink plate connecting direct current electrodes of the elements with one of terminals of the power source, and phase heat sink plates connecting respective alternating current electrodes of the elements with respective multiphase terminals of a motor. The elements of each module correspond to all phases of an alternating current. Each common heat sink plate forms a principal surface of the corresponding module, and the phase heat sink plates of each module forms another principal surface. The principal surfaces of each module face each other along the stacking direction.
