Characterization of Losses and Inductance in Actively Biased Variable Inductors

Previous studies have primarily focused on the magnetic coupling behavior between the main and auxiliary winding under symmetrical bipolar operation conditions. However, practical power electronic systems often operate under combined ac-excitation and superimposed dc-bias currents applied to the main winding. To addres...
