Abstract: A power converter having a busbar device includes at least one ferrite core filter and at least two busbars, which are spaced from one another in an electrically insulated manner. The busbars may have different electric potentials, so that the busbars can carry an electric current appropriate for a bar cross-sectional area. The busbars are guided at least once through at least one feed-through opening of the ferrite core filter. The busbars are one piece in each case, and are reshaped by a bend formed in a passage area of the feed-through opening, and a passage cross-sectional area of the busbars in the passage area is at least the same size as the bar cross-sectional area, so that the busbars can carry the same electric current along the run of the busbars.

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.

Abstract: Fluid pumping system for a vehicle with an internal combustion engine, the fluid pumping system comprising: a housing; an electric motor; a planetary gear with a first member that can be driven by the internal combustion engine, a second member driven by the electric motor, and a third member; and a pump driven by the third element of the planetary gear set, the housing being closed by a pump flange and a pulley with pulley cover, wherein at least the pulley and/or a ring gear disposed in the pulley is made of plastic.

Abstract: A pump assembly for a motor vehicle, comprising at least one mechanical drive, at least one electric drive, and at least one planetary gearbox, wherein the mechanical drive and the electric drive are coupled to one another via the planetary gearbox, the electric drive comprising a rotor shaft that is designed as a hollow shaft, wherein the rotor shaft is mounted at one side on a housing of the pump assembly via a ball bearing and at the other side in a gear stage of the planetary gearbox.
