Abstract: A power electronic system with a cooling device, and a method for producing the system, comprising a plurality of submodules, each submodule having a first planar insulating material body, one first conductor track cohesively connected thereto, one power switch arranged on the conductor track, at least one internal connecting device composed of an alternate layer sequence of 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 comprising external connection elements. In this case, the submodules are arranged cohesively or in a force-locking manner and in a manner spaced apart from one another with their first main surface on the cooling device. 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 the submodules.
