ABSTRACT:
An ac-to-dc switching full-bridge converter employing voltage bidirectional switches as controllable series input switches, preferably implemented with magnetic amplifiers, that couple ac rectifiers to a single-stage full-bridge dc-to-dc converter in order to provide unity power factor operation by control of input current using a fast current loop to modulate the duty ratio d1 of the voltage bidirectional amplifier switches while independent output voltage regulation is maintained by voltage feedback to the full-bridge converter switches through modulation of the switch duty ratio d of the converter (where d1<d) using an independent fast output regulation loop.
