A power converter, includes a housing and a busbar arrangement, which is arranged inside the housing, wherein the power converter is designed to guide an alternating current along the busbar arrangement, the power converter also includes at least one planar flux-conducting element made of a magnetically highly permeable material, which is arranged between a wall of the housing and the busbar arrangement.

Power converter, arrangement comprising an electric machine and a power converter, and vehicle

The invention relates to a circuit device () for reducing common-mode interference of a power converter (), the power converter () forming a common-mode interference source during operation. The circuit device () comprises at least one short-circuited additional line (), which can be coupled to an input () and an output () of the power converter (). The additional line () conducts the interference currents produced by the common-mode interference source and returns said interference currents to the common-mode interference source.

The present invention relates to interference suppression of interference signals from an inverter. To this end, an inductor is provided at the input end of an inverter, in particular a pulse-controlled inverter. This inductor is preferably arranged between a DC voltage source and the inverter. Furthermore, two capacitors, one side of which is connected to an additional conductor, are provided between the inductor and the DC voltage source and further capacitors, one side of which is likewise connected to the additional conductor, are provided at the phase connections of the inverter.
