摘要：
A new single-stage power factor correction (SSPFC) converter is proposed for the adapter application, which is composed of a flyback converter and a front-end input current shaper. Low conduction losses are achieved with only two diode conduction drops in the primary side. The conversion efficiency is improved with a direct energy transfer path, which is provided by the feedback wingding. Equations and configurations are given to design the input current shaping (ICS) inductor and the magnetizing inductor of the transformer operating in discontinuous conduction mode (DCM) or in DCM/CCM boundary mode. The good performance of the converter is verified experimentally on a 90W (19V/4.74A) SSPFC converter with universal line input.
