摘　　要：提出了一种新型的功率因数校正模块(flyboost模块),它具有两种工作状态(反激变换器状态和Boost电感状态) 基于这种PFC模块,得到了一种新型的单级PFC变换器,实验证明这种变换器不仅可以得到很高的功率因数。A novel single stage power factor correction cell( flyboost cell ) is presented. This PFC cell has two operating states (flyback state and boost mductor state) Rased on this cell, a novel single stage PFC. converter is derived. It is proved by experimental results that we can achieve a high power factor. Also we can improve the efficiency of the converter and auto-matically limit the voltage on the bulk capacitor.
