Single-Stage PFC AC/DC Full Bridge Converter의 소프트 스위칭에 관한 연구
A Study on Soft Switching of Single-Stage PFC AC/DC Full Bridge Converter
초록
This paper proposes a new soft switching single stage AC/DC full bridge converter with unit power factor and isolated output. This circuit shows that it is possible to combine the boost converter which is for PFC(Power Factor Correction) and full bridge converter which is for DC/DC converter. A simple auxiliary circuit which includes neither lossy components nor active switches eliminates ringing of secondary side of the transformer. The characteristics of the proposed circuit are investigated and the validity is verified by the simulation results.
