Abstract :
Passive current sharing in multiphase converters, where resistive losses are not dominant, is a quite complex goal. In this paper an averaged model of an active clamp converter was obtained. It has been checked that these topologies present high output impedance. This property is used like a lossless passive equalization. Simulated results of the average model accuracy and current sharing are presented.
