Abstract
The method, apparatus and system of a single-stage current-fed clamped series resonant power factor corrected (PFC) converter CF-CSRC provides power conversion and current regulation. The CF-CSRC system may be implemented in a single-stage isolated topology for high efficiency unity power factor correction (PFC) converter applications. Moreover, the CF-CSRC system combines the intrinsic advantages of the classical clamped series resonant converter while mitigating drawbacks by using an integrated boost input current shaper.
