A power module includes at least two power semiconductor arrangements, each having at least one semiconductor component, in contact with substrate and arranged in a housing. To improve the reliability of the power module, a first power connector and a second power connector are arranged on a first side of the housing and at least one other power connector is arranged on an opposing second side of the housing. Supply lines extending from the power connectors to the power semiconductor arrangements are arranged on the substrate in such a manner that electrical current is provided in a symmetrical manner.

A converter filter includes an inductor having a main winding and a winding element, and first and second absorption circuits coupled to the inductor. The first and second absorption circuits are decoupled from one another by an inductance of the winding element of the inductor. An auxiliary winding is coupled to the inductor and forms a 1:1 transformer with the winding element. The auxiliary winding is fed via the inductance of the winding element. The auxiliary winding and the second absorption circuit are each connected to an output of the winding element and the first absorption circuit is connected to the auxiliary winding.
