Abstract: The invention relates to a power converter having a busbar device, a method for producing a busbar device and a busbar device for carrying and distributing electric currents, having at least one ferrite core filter and having at least two busbars, which are spaced from one another in an electrically insulated manner, it being possible for the busbars to have different electric potentials, so that the busbars can carry an electric current appropriate for a bar cross-sectional area, and the busbars being guided at least once through at least one feed-through opening of the ferrite core filter.
