Abstract: A permanent magnet DC inductor is disclosed which includes at least two separate and individual magnetic inductors, each having its own core structure and forming closed individual magnetic paths having at least one magnetic gap. Windings are provided on the magnetic cores, and at least one permanent magnet piece is provided with each inductor. The separate magnetic cores having the at least one magnetic gap are arranged against each other to form external magnetic gaps with the permanent magnet pieces arranged inside the external magnetic gaps on both sides of the at least one magnetic gap.

Abstract: A reactor arrangement for alternating electrical current includes different coils (105, 107) for positive and negative half-cycles of the alternating electrical current. The negative and positive half-cycles of the alternating electrical current are directed to the different coils with the aid of unidirectional electrical components (106, 108) such as, for example, diodes. The both coils are arranged to magnetize a common magnetic core element (104) in a same direction. The reactor arrangement further includes at least one permanent magnet (109) that generates, into the magnetic core element, a biasing magnetic flux component having an opposite direction than that of magnetic flux components generated with the coils. Therefore, the biasing magnetic flux component generated with the permanent magnet relieves magnetic saturation of the magnetic core element. Hence, the size and the weight of the magnetic core element can be reduced.
