1. A coupled-inductor current-doubler topology for a power converter, comprising:
first and second rectifiers; and
a first coupled inductor that is magnetically separated from a second coupled inductor, each coupled inductor having a main inductor inductively coupled with a secondary inductor, the secondary inductor of the first coupled inductor electrically coupled in series with one of the first and second rectifiers and the secondary inductor of the second coupled inductor electrically coupled in series with the other one of the first and second rectifiers.
