Abstract
A controller for a full bridge power converter having controllable switches, a method of operating the controller and a power supply employing the controller or the method. In one embodiment, the controller includes (1) a signal generator circuit designed to drive the controllable switches in a phase-shifted mode and (2) a switching network, coupled to the signal generator circuit, adapted to enable the signal generator circuit to operate the converter in an alternative one of (2a) the phase-shifted mode, wherein the controllable switches in each of first and second legs of the converter are complementarily switched, the signal generator circuit capable of adjusting a relative phase between the first and second legs and (2b) a normal mode, wherein diagonal pairs of the controllable switches are switched substantially simultaneously and at a substantially full duty cycle.
