Abstract

This paper presents a new topology resulting in a combination of two forward structures, attached to the same transformer and operating as a full-bridge. The transformer and the output filter operate with twice the forward switching frequency. Each one of these forward converters has a ZVS commutation cell in the turn on and turn off that allows high switching frequency, high power operation and high efficiency to a wide load range
