A novel ZCZVT soft-switching single-stage high power factor correction converter

On the basis of the single-stage high power factor correction converter, the soft-switching technology is applied to design a novel converter with zero-current-zero-voltage-transition (ZCZVT). The converter has the advantages of high power factor, low current harmonic distortion, and high switching efficiency. The operation of the converter is presented in this paper. The accuracy of theoretical results is verified by the simulation of IsSpice and experimental results.
