Self-adaptive zero current prediction (SAZCP) technique for auxiliary winding-free boost power factor correction controller

Autor: Che-Hao Meng, Chih-Wei Chang, Ke-Horng Chen

Publikováno v: 2013 1st International Future Energy Electronics Conference (IFEEC).

Power factor correction (PFC) can shape the input current of off-line power supplies to be in-phase with the input AC voltage to maximize the available real power from the AC source for high power factor (PF). Considering high PF and efficiency, the
