摘　　要：针对目前PFC电路拓扑门类繁杂,且大多集中在升压型及其改进型PFC电路上,对于降压型PFC电路研究较少的现状,基于大量文献,文章首先对国内外多种降压型PFC电路拓扑进行介绍总结,之后重点介绍了三相降压型PFC电路拓扑,说明了各类电路拓扑的优缺点,最后分析了PFC技术的发展方向,为进一步研究PFC技术提供参考。In view of the current situation that PFC circuit topologies are complex and mostly concentrated on boosttype and improved PFC circuits,and there is little research on buck-type PFC circuits,through reading a lot of literature,this paper firstly summarized and analysed various buck-type PFC circuit topologies at home and abroad and then the threephase buck PFC circuit topology was analyzed.The advantages and disadvantages of various circuit topologies were explained.Finally,the future development direction of PFC technology was pointed out,which provided some guidance for further study of PFC technology.
