A new modular 3-phase AC-DC flyback converter for telecommunication

A novel mode of parallel operation of a modular three-phase AC-DC flyback converter for power factor correction along with tight regulation was recently analyzed and presented. The advantage of the proposed converter does not require expensive high voltage and high current devices that are normally needed in popular boost-type three-phase converter. In this paper, the detailed small signal analysis of the modular three-phase AC-DC flyback converter is provided for control purposes and also experimental results are included to confirm the validity of the analysis.
