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 buck converter
was obtained. It has been checked that this topology presents
high output impedance. This property is used like a lossless passive
equalization. The principle of operation, theoretical analysis,
simulation, and experimental results are presented, taken from a
three-stage laboratory prototype.
