Title

Power Factor Correction Circuits

Abstract

This chapter gives a technical review of current research in high frequency power factor correction (PFC), including the definition of power factor (PF) and total harmonic distortion (THD), configuration of PFC circuit, discontinuous conduction mode (DCM) input technique, and continuous conduction mode (CCM) shaping technique. Research on harmonic reduction and PFC has become intensified in the early nineties. With the rapid development in power semiconductor devices, power electronic systems have matured and expanded to new and wide application range from residential, commercial, aerospace to military and others. Power factor is a very important parameter in power electronics because it gives a measure of how effective the real power utilization in the system is. Because of their high reliability and high power handling capability, passive power factor correctors are normally used in high power line applications. Comparing with the other type of high frequency PFC circuits, the buck corrector offers inrush-current limiting, overload or short-circuit protection, and over-voltage protection for the converter due to the existence of the power switch in front of the line. © 2011 Elsevier Inc.
