A converter arrangement includes a basic structure having a receptacle, a first electrical network including lines arranged on the basic structure, a plurality of first contacts arranged on the basic structure and movable via a first actuator from a first connection position into a first release position, and a converter assembly securable in the first release position as a unit in a fixed location in the receptacle of the basic structure and removable from the receptacle. The converter assembly is electrically connected to the lines of the first electrical network when the first contacts assume the first connection position, and electrically disconnected from the lines of the first network when the first contacts assume the first release position. The receptacle of the basic structure is immobile when the first contacts move from the first connection position into the first release position.

Converter arrangement comprising movable contacts, but immovable converter assembly

A power converter module with a liquid-cooled heat sink, a busbar arrangement having at least two busbars, at least two power semiconductor modules, which are mechanically connected to the liquid-cooled heat sink for thermal conduction and are electrically connected to connections of the power converter module by the busbar arrangement has at least one coolant line forming a single structural unit with the busbar arrangement. The coolant line prevents additional power loss in the laminated busbar.

Power converter module with cooled busbar arrangement

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.
