摘要: Two-stage power factor correction (PFC) configuration usually suffers from low conversion efficiency due to twice processing. Detailed analysis and operations of a hybrid mode PFC pre-regulator which employs both active passive techniques at different time slots are presented. The approach can achieve high efficiency, as well output voltage stresses on switch bulk capacitor. Furthermore, analyses PF losses components with the circuit inductance also discussed. Experiments were performed verify effectiveness approach.
