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.
