Active Power Factor Correction in Power Converter for Single Phase Power Supply

Abstract

Due to nonlinear load, Electrical appliances with switching devices draw high input current in short period of time. Low power factor results in poor output voltage regulation and increased total harmonic distortion. Power factor correction is frequently adopted to rectify this problem, which when on applied, Improves the power factor, and hence the efficiency. This paper describes choice of suitable power converters and the power factor correction methods applied on them
