POWER ELECTRONIC SUBASSEMBLY WITH CAPACITOR

摘要

A power electronic subassembly having a housing and a capacitor arranged therein. The housing has an internally arranged cooling area, which is cooled by a cooling device integrated in the housing or an external cooling device. The capacitor has a contact device of a first polarity and a contact device of a second polarity and a capacitor busbar system. This capacitor busbar system comprises first and second sheet-like shaped metal bodies. The first metal body with the first contact device of the first polarity and the second metal body with the second contact device of the second polarity are electrically conductively connected. A first portion of the first metal body has a first subportion, which is arranged parallel to and at a distance from the cooling area, and a second subportion, which is in thermal contact with the cooling area, wherein the two subportions are connected by an intermediate portion.
