Beschreibung
Zusammenfassung:	In certain embodiments, a power converter has an input side connected to receive AC input power at an input node and an output side connected to produce a regulated output power at an output node. The power converter has a transformer having at least one primary winding on the input side and at least one secondary winding on the output side. The power converter has at least one multi-functional inductor that supports both main regulation and supplemental regulation in a time-multiplexed manner such that, during main regulation, input energy is transferred from the input node to the output node via the multi-functional inductor, and, during supplemental regulation, the stored energy is transferred from the at least one energy storage element to the output node via the multi-functional inductor. Depending on the embodiment, the multi-functional inductor(s) may be one or two secondary transformer windings or a separate buck inductor.
