ABSTRACT:
For use in a DC/DC converter fed by a three phase rectifier, an active circuit and method for delivering an inner phase of three phase AC input power provided to the rectifier and a power converter employing the active circuit or the method. The active circuit includes: (1) a phase selection switching circuit, coupled to the rectifier, that selects an inner phase of the three phase AC input power and (2) a switching network, coupled to the phase selection switching circuit, that controls a waveshape of at least the inner phase to the DC/DC converter thereby to reduce harmonics associated with the three phase AC input power.
