ABSTRACT:
An asymmetrical half-bridge converter, a method of operating the same and a power supply that incorporates either the converter or the method. In one embodiment, the converter includes: (1) a power transformer that receives asymmetrical AC input power into a primary winding thereof via an input capacitor, the asymmetrical AC input power inducing a DC bias current in a secondary winding of the power transformer and (2) first and second serially-coupled output inductors coupled across the secondary winding and having parasitic resistances associated therewith that are independently selectable to attenuate the DC bias circuit in the secondary winding.
