Abstract :
This paper introduces a new forward converter topology that uses the full hysterisis cycle with two symmetric forward converters coupled in a single magnetic core. It also presents lossless commutation when turning on and off managed by an LC circuit and auxiliary switches. As a result, high frequency switching can be achieved not increasing the switching losses
