Abstract

Bridgeless positive output Cuk LED driver operated under universal supply (90 V to 240 V) voltage for indoor applications with improved AC source power quality has been presented. The undesirable harmonic content in the supply current due to the operation of conventional diode bridge rectifier (DBR) based two stage LED driver is greatly reduced by the proposed single stage (bridgeless) LED driver with very simple control circuit. Therefore, high efficient operation along with low total harmonic distortion (THD) and high power factor can be acquired. Performance of the Cuk LED driver has been analysed under various LED load power provided with universal supply voltage in simulation study. Experimental results agree with the simulation results. The results guarantee the stable operation of LED driver with regulated DC link voltage and upgraded power quality satisfying IEC 61000-3-2 class C standards..
