Abstract :
This paper presents a new single-phase power-factor-corrected (PFC) AC/DC voltage regulator using a parallel power processing scheme. By combining a PFC cell and a DC/DC cell into a new power converter structure, higher conversion efficiency than those of the conventional cascaded configurations can be achieved while maintaining good power factor and fast output voltage regulation. Moreover, the storage capacitor voltage is kept reasonably low. Experimental results are given to verify the converter characteristics. This converter formation concept can also be extended to generate other useful topologies
