Abstract

This paper presents a single-stage LED driver for street lighting applications with a novel bridgeless power factor correction converter. The proposed single-stage topology integrates a bridgeless PFC converter and a half-bridge CLCL resonant converter by sharing active power switches. The bridgeless PFC converter here adopts two buck-boost circuits operating at discontinuous conduction mode to achieve input-current shaping and it uses two diodes instead of rectifier bridge to reduce the power loss on diodes. Due to the superior characteristic of soft-switching, the CLCL resonant converter is employed. The proposed LED driver has the features of high efficiency, nearly unity power factor, low THD and relatively low number of diodes. A 100W lab prototype is successfully implemented and the experimental results verify the effectiveness and feasibility of system.
