Abstract

The invention relates to a system, including a bus bar device and a power converter housing, wherein the bus bar device includes a stack made of at least two bus bars and an electrically insulating insulation body, which encloses the bus bars in two insulating regions of the bus bar device, wherein each bus bar includes two opposing base surfaces extending in the direction of current flow and lateral surfaces connecting the base surfaces and extending in the direction of current flow, wherein the bus bar device includes a temperature control region formed between the insulating regions, in which the insulation body has an opening that exposes one of the lateral surfaces and a portion of at least one of the base surfaces of a respective bus bar, wherein the bus bars are thermally connected to the power converter housing in the temperature control region by a heat transfer means.
