Abstract

A flyback converter is provided in which either auxiliary winding or the primary winding is split into two windings. In this fashion, a different turn ratio is presented to the secondary winding during the transformer reset period as compared to when an active-clamp transistor or a ZVS switch transistor is switched on.
