Abstract :
Recently global suppliers of telecom energy solutions have been researching alternative rectifier topologies capable of processing high power using ohmic isolation with compact size. This paper introduces a new concept of a single-stage high-frequency isolated three-phase AC/DC converter. In order to validate this topology, forward/flyback converters and three-phase buck rectifiers are briefly reviewed. This paper also presents a modeling and control technique proposal. The theoretical concepts are verified by the digital simulation of a rectifier connected to a 220 Vrms grid delivering 6 kVA at 60 V/100 A
