摘要：

PFC (Power Factor Correction) power supplies are required to provide high input power factor and tight output voltage regulation [1]. Through analyzing the characteristics of various PFC converter modes, this paper is about the design and simulation of a boost PFC pre-regulator. This boost PFC pre-regulator takes advantage of both CRM(Critical Conduction Mode) and DCM(Discontinuous Conduction Mode) operating modes that can help to simplify the front-ended filter design, to reduce the costs and to improve the reliability of the circuit. Andthis paper presents a 100W PFC circuit and the computation methods of essential circuit parameters. The experimental results prove that the PFC circuit has the following characteristics: simple circuit, convenient debugger, high power factor, reliable and stable work.
