Subtag of DC-DC-conversion

Anything about flyback converters, a type of DC-DC converter topology.

A flyback converter is a galvanically isolated converter, in which a transformer is used to deliver power (after rectification) to the load. The feedback signal needed to maintain output voltage regulation is fed back to the primary (switching) side of the transformer either by an auxiliary transformer, by optical coupling using an optoisolator or using an auxiliary winding of the main flyback transformer itself.
