A Novel PFC AC/DC Converter for Reducing Conduction Losses
초록
This paper presents a novel Power Factor Corrected(PFC) single-stage AC/DC Half-Bridge converter, which features discontinuous conduction mode(DCM) and soft-switching. The reduced conduction losses are achieved by the employment of a novel power factor correction circuitry, instead of the conventional configuration composed of a front-end rectifier followed by a boost converter. To identify the validity of the proposed converter, simulated results of 500[W] converter with 100[V] input voltage and 50[V] output voltage are presented.
