INDUCTIVE COMPONENT

摘要

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.
