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.

Claim (Index 7):
The apparatus of  claim 3 , wherein the digital controller further comprises a control parameters calculator to:\n conduct a comparison between the bulk voltage at a first time and a second time, and a comparison between the output current at the first time and the second time; determine a steady-state when the bulk voltage and the output current stabilize based on the comparison between the bulk voltage at the first time and the second time, and the comparison between the output current at the first time and the second time; and adjust the duty-cycle at a slower rate relative to a rate of adjusting the switching frequency.
