Abstract
A power converter module has a first liquid-cooled heat sink, a busbar arrangement having at least two busbars which are electrically insulated from one another and at least one power semiconductor module which is mechanically connected to the first liquid-cooled heat sink for thermal conduction and electrically connected to connections of the power converter module by the busbar arrangement. A second liquid-cooled heat sink is positively or non-positively connected to the busbar arrangement. A thermally conductive and electrically insulating layer is disposed between an upper busbar of the busbar arrangement and the second liquid-cooled heat sink. Additional power loss arising in the busbar is dissipated by the second liquid-cooled heat sink, which is pressed with a clamping elements on a surface of the upper busbar.
