Abstract:
1. A power electronic system with a cooling device, the system comprising: a plurality of submodules, each of said submodules having a first planar insulating material body, a single first conductor track cohesively connected thereto, a single power switch arranged on said first conductor track, at least one internal connecting device composed of an alternating layer sequence of at least three layers, said at least three layers including at least one electrically conductive film and at least one electrically insulating film; wherein at least one electrically conductive layer forms at least one second conductor track, and includes external connection elements; wherein said submodules are arranged in one of a cohesively and a force-locking manner, and are spaced apart from one another with their first main surface in thermal contact with the cooling device; and wherein said at least one second conductor track at least partially covers first conductor tracks of two submodules, electrically connects them to one another and covers an interspace between said two submodules.
