Power converter module with cooled busbar arrangement
First Claim
1. A power converter module, comprising:
- a liquid-cooled body;
a busbar arrangement having at least two busbars;
an insulation layer comprising two insulating layers which are materially connected with one another so as to produce between the two insulating layers a cavity of a predetermined shape, said insulation layer providing insulation between the at least two busbars;
an entrance side and an exit side disposed on least one side face of the insulation layer;
a connector arranged on the entrance side and the exit side and fluidly connected to the liquid-cooled body; and
at least two power semiconductor modules, which are mechanically connected to the liquid-cooled body for thermal conduction and are electrically connected to terminals of the power converter module by the busbar arrangement.

Abstract
A power converter module includes at least two power semiconductor modules, which are mechanically connected to a liquid-cooled heat sink and electrically connected to terminals of the power converter module by a busbar arrangement having at least two busbars. The busbars are insulated from one another by an insulation layer. The insulation layer is composed of two insulating layers, which are materially connected with one another so as to form therebetween a cavity having a predetermined shape and an entrance side and an exit side disposed on least one side face of the insulation layer. A connector is provided on the entrance side and the exit side and fluidly connected to the liquid-cooled heat sink. The rectifier module is thus able to sustain relatively high electrical loads compared to conventional rectifier modules, while maintaining a permitted temperature for the insulation layer and the lamination material of the busbar.
