Abstract
Single phase inductors have non-linear inductance values, and M-phase coupled inductors having non-linear leakage inductance values. Each inductor includes, for example, at least one of the following: a saturable magnetic element, a gap of non-uniform thickness, a core formed of a distributed gap material, or a non-homogeneous core. A DC-to-DC converter includes an inductor having a non-linear inductance value, a switching subsystem, and an output filer. Another DC-to-DC converter includes an output filter, a coupled inductor having non-linear leakage inductance values, and switching subsystems.
