Abstract
An inductor and method of operating the inductor by combining primary and secondary coils with passive coupling, active parallel, or active cross-coupling structures. The first includes at least one passive coupling structure having at least one coupling coil arranged between a primary coil and at least one of the secondary coils and/or between two of the secondary coils. The second includes an active coupling structure arranged between a primary coil and at least one secondary coil and/or between at least two of the secondary coils, to selectively parallel couple the primary coil and one of the secondary coils and/or at least two of the secondary coils. The third includes an active coupling structure to selectively cross couple a primary coil and at least one of the secondary coils and/or to selectively cross couple at least two of the secondary coils.
