Abstract

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.
