Analysis of Material Mixtures for the Characteristics of a Field Coupled Current Controlled Adjustable Inductance

In this paper the realization of a concept for an adjustable inductance with different composites of magnetic core material is described, analyzed and discussed. An electrical circuit is used to generate a magnetic field by an additional control core which is orthogonal to the magnetic field of the load core and thereby change the inductance. It is shown that the system can be influenced in different ways by the chosen material mixtures.
