A single-stage ac/dc converter with high power factor and low power loss

고역율, 저손실 1단 교류/직류 변환기

In this paper, we propose a new single-stage isolated switching power supply. The proposed converter reduces the diode conduction loss and offer both the high input Power factor and the direction conversion from the ac line to a dc output voltage. This paper present the Operational principle, analysis and control and experimental results of a 100W prototype.
