ABSTRACT:
To improve EMC shielding for an electronic unit containing at least one electronic power device operated at high frequency and a metal housing thermally coupled to the device to provide heat dissipation, the power device with a device terminal is thermally and electrically coupled to a first metal plate. The first metal plate is coupled in turn to a second metal plate in a particular manner via a first insulating layer. A metal housing with a heat sink through which a cooling fluid can flow is disposed, on another side of a second insulating layer. The improvement in EMC is based on an internal short-circuiting of an interference current produced by the power device over a very short loop.
