ABSTRACT:
A power converter is provided with a pair of auxiliary windings coupled to the primary windings of the output transformer which serve as energy choke windings. An additional pair of choke windings are coupled between the input of the converter to a common terminal of the primary winding. These choke windings prevent excess voltage from appearing across the switching devices of the converter during the turn-off portions of the cycle.
