ABSTRACT:
In order to reduce the commutation inductance of series-connected controllable semiconductor components (V1-V6), the latter are connected, in an essentially orthogonal manner and at a predeterminable distance (a), via spur double striplines (6, 6') to essentially planar main lines (5, 5'). All of the double striplines (5, 5'; 6, 6') have a layered structure and are mutually insulated by a thin insulating layer (7), with the result that a minimum current area is achieved. The controllable semiconductor components (V1-V6) are accommodated closely adjacent to freewheeling diodes in a module (10), the heat of which can be dissipated by cooling elements (8). Bipolar transistors having an insulated gate (IGBTs) are preferably used as controllable semiconductor components (V1-V6).
