Abstract

A large signal simulation for a distributed power supply system is presented in this paper. The system is composed of two parallel-connected switched-mode power factor correction (PFC) converters utilizing a central limit control technique. This technique allows one voltage loop compensator to be shared by all the PFC converters. The design of such a compensator is discussed and the system performances with regard to unequal cable resistances and load changes are reported. The resulting system features a universal input with a power factor greater than 0.98 and provides excellent current sharing among the converter modules
