Power Factor Corrector for Lighting Applications Using LUO Converter

Abstract

The power factor achieved by the incandescent lamp is not same as the power factor achieved by the compact fluorescent lamp. The existing system used electronic-ballast for power factor correction, it has the disadvantage of using large dc-link capacitor which introduces high distorted input current and results in high harmonics and low power factor. The proposed system consists of LUO converter with pulse width modulation. LUO converter produce low power density and high efficiency, similarly pulse width modulation is used to improve the lamp current crest factor and reduce the power loss.
