选择正确的PFC解决方案

Choosing the Right Power Factor Controller Solution

本文用一种创新的方法提出了四种功率因数校正(PFC)电路设计。两种临界导通模式(CRM)升压,一种连续导通模式(CCM)升压和一种CCM单段回扫,并且推荐了基于功率要求、效率、失真程度、电路板空间和成本限制的解决方案。

In an innovative way, This paper presents four PFC circuit designs; two critical conduction mode (CRM) boost,one continuous conduction mode (CCM) boost, and one CCM single stage flyback and recommends the bestsolution based on power requirements, efficiency, distortion level, board space, and cost constraint.
