Ga. Karvelis et Sn. Manias, ANALYSIS AND DESIGN OF A FLYBACK ZERO-CURRENT SWITCHED QUASI-RESONANTAC DC CONVERTER/, IEE proceedings. Electric power applications, 144(6), 1997, pp. 401-408
A flyback zero-current switched (ZCS) quasiresonant AC/DC converter, f
unctioning as a power factor correction regulator, is presented and an
alysed in detail. Only one active switch with simple control logic is
required to achieve both input current waveshaping and output voltage
regulation. The investigation of voltage and current waveforms of the
proposed converter is followed by simulation and leads to a design exa
mple to verify the theoretical results. An experimental unit of 120 W
was built which confirmed the analysis and simulated results.
