Abstract:
This paper introduces a novel constant frequency switching PWM converter,as well as some improvements on the conventional bridge parallel resonant converters. By introducing mutual inductance and auxiliary into the original circuit topology ,a class of novel zero current switching multi-resonant converters regulated by PWM mode at a fixed switching frequency are presented,which overcomes some drawback of the original circuits.One illustrative example is analyzed and the experimental results are given, which confirms the advantages of this approach.
