Abstract
An active two-terminal inductor device with a controllable inducitance based on an inductance value input L_I. A processor system PRS executes an algorithm which controls a power converter PCV with controllable electric switches connected to the two external terminals A, B along with a fixed value inductor component L. Based on sampling of at least a voltage or a current in connection with the inductor component L, the algorithm controls the power converter PCV to provide a resulting inductance across the external terminals A, B which serves to match the inductance value input L_I.
