ENERGY CHANNELING LED DRIVER TECHNOLOGY TO ACHIEVE FLICKER FREE OPERATION WITH ZETA CONVERTER FOR POWER QUALITY IMPROVEMENT

Abstract

This paper presents a flicker free operation of light emitting diode (LED) driver with Zeta converter for low power applications. In this work, the power factor of the LED driver is achieved by Zeta converter and it is operated in Continuous Conduction Mode (CCM). Further, the Zeta converter provides continuous current for an output system. Further, the design and simulation of the proposed circuit is done using MATLAB/Simulink software. Results demonstrate that the closed loop control system using fuzzy logic controller for the proposed LED driver provides good voltage regulation. Also, the proposed design and operations have been practically verified with a 40W LED driver module.
