Power Factor Correction AC/DC Converter with Short-term Blackout Tolerance

순시정전보상기능을 가진 PFC 회로

In this paper, a method to cope with short-term blackout is proposed. The proposed method uses a capacitor bank consisting of supercapacitors. A supercapacitor is a good means for short-term energy storage. The proposed circuit is simple and accordingly easy to construct and to control. A prototype is constructed and experimental results are presented.
