Abstract

This paper presents a single phase power factor correction (PFC) power supply topology based on a non-cascading connection of a current-fed full-bridge converter and a buck-boost converter, both converters being operated in continuous conduction mode (CCM). Due to the reduced redundant processing of power, the non-cascading structure can inherently achieve a higher overall efficiency compared to the classical two-stage cascade structure. An analysis of the reduced redundant power processing (R2P2) principle is given and the associated practical problems discussed. Experimental results verify the effectiveness of the non-cascading structure of the proposed topology as an appropriate solution for increasing the overall efficiency.
