A review of single phase power factor correction A.C.-D.C. converters

The demand for solid state A.C.-D.C. converters to enhance power quality in the expression of P.F.C. (Power Factor Correction) impels the proposal of miscellaneous topologies. These converters are expected to reduce the total harmonic distortion (T.H.D.) at A.C. input and accurately regulate D.C. output in Buck, Boost, Buck-Boost and multi-level models considering both unidirectional and bi-directional power flows. This paper presents an exhaustive review of I.P.Q.C.s (improved power quality converters) configurations, design features, and selection for specific. The paper is aimed to present a broad perspective on the status of I.P.Q.C. technology to researchers, designers and application engineers working on clean energy and smart grid fields.
