摘要： A converter device comprising a converter and a coil arrangement that contains a number of coils. The coil arrangement has a plurality of interconnected coils. Torroidal cores of a soft magnetic nanocrystalline material are associated with each of said coils. A coupling toroidal core (11) is provided with a core opening (12) through which at least two windings (8, 9) of different coils can be guided and mounted. At least the winding of one coil is guided and mounted through a core opening of an individual toroidal core (13, 14). An an open/closed-loop control device is provided with a current controller that acts on the coils such that direct current components are compensated by currents flowing through the windings of the coils.

摘要： A electromagnetic device may include a core in which a magnetic flux is generable and an opening through the core. A primary conductor winding may be received in the opening and extend through the core. A primary electrical current signal flowing through the primary conductor winding generates a magnetic field about the primary conductor winding and a first magnetic flux flow in the core. A secondary conductor winding may be received in the opening and extend through the core. A first modular conductor winding may extend through the opening and encircle a first outer core portion of the core. A first modulation signal flowing through the first modular conductor winding modulates the primary electrical current signal to provide a modulated output current signal at an output of the secondary conductor winding.

摘要： The present disclosure relates to filters. Teachings thereof may be embodied in a filter assembly, e.g., a filter assembly for filtering output currents from a voltage converter. For example, a filter assembly may include: a current conductor with a curved profile; a first ferrite body; a second ferrite body; and a recess with a curved profile defined in at least one of the first ferrite body and the second ferrite body. The first ferrite body and the second ferrite body may combine to surround the current conductor and the current conductor may extend along the recess.
