Magnetic devices are an important part of electronic converters. They can be used to control some properties of the converters. There are three different control methods using an auxiliary bias-winding. In the presented paper, the impact of the implementation of the auxiliary bias-winding was studied for mixed biasing. Seven different designs were investigated in small signal measurements and 3D-FEM-simulations. The results were proven by calculated results of equivalent diagram circuits, which have been developed. Regarding the standard crosswise current arrangement all designs show the same results. In a horizontal aux. current arrangement, the effect of the VAG technique is mitigated. Investigations of a vertical aux. current arrangement results in an unsymmetrical magnetization curve.
