摘要
有源功率因数校正器(Active Power Factor Correction,APFC)是开关电源的发展趋势之一,而其中的单级功率因数校正器(Single-Phase Single-Stage PFC)由于控制简单、成本低,成为目前APFC研究的热点之一。文章针对单级功率因数校正器,介绍其优点和存在的一些缺点,并介绍几种较新的拓扑。
APFC is one of the development trend of switching power supply, the simple control and low cost make singlephase single-stage PFC become the focus in the research of APFC. The advantages and drawbacks of single-phase singlestage APFC are discussed, along with some of its new topologies.
