Abstract: The invention concerns a medium frequency transformer with a housing, in which numerous winding chambers, having primary and secondary windings, are disposed, wherein the housing is filled, at least partially, with an insulating liquid. The transformer is distinguished in that numerous winding chambers, filled with the insulating liquid, are disposed in the housing, and at least one winding is disposed in each winding chamber, such that, for the most part, only the windings are surrounded by the insulating medium. Preferably the winding chambers are sealed and separated from one another by means of insulating separating walls, wherein the windings are positioned and fixed in place in the winding chambers, and the winding chambers are filled with the insulating liquid. Between the windings there are thus, according to the invention, at least two insulating barriers, which function simultaneously and consist of solid matter insulation in the form of housing and separating walls, and the insulating liquid.

Abstract: An inductive component with a magnetic circuit is made of a magnetically soft core material, the circuit having at least one gap which extends in the Y direction from a first end-side free end of the core material to an opposite second end-side end of the core material, at least one coil which is wound around at least one part of the core material, and a permanent magnet unit which consists of multiple mutually spaced individual permanent magnetic elements, each of which has a magnetizing direction, the directions oriented in an at least approximately identical manner to the Y direction The individual magnets are stacked next to one another in a mutually spaced manner in a direction which is at least approximately orthogonal to the Y direction. There is high magnetic biasing of the inductor by means of the permanent magnets, little power loss, a simple production, and a high fill factor.
