WebJan 27, 2015 · A flyback transformer is nothing more than a dual winding inductor. The inductor's magnetic field is charge through the primary, then discharged through the secondary, with a voltage multiplication (and current division) equal to the turns ratio of secondary over primary. Actually, quite a bit simpler than an AC transformer!
