ABSTRACT:
A transformer with a plurality of secondary windings with substantially similar coupling to the primary winding is used to facilitate synchronous rectification of the output by a rectifier attached to each secondary winding, reducing power losses compared to conventional power supplies with a single secondary winding coupled to a single rectifier. In a preferred embodiment, the transformer comprises at least two primary windings, with each primary winding coupled to at least two secondary windings.
