Abstract

Light Emitting Diode (LED) inherently acts as a diode which allows the current in one direction and this can be achieved by AC-DC converter. It is essential to have sinusoidal input current wave shape and constant load current to drive the LED without any flicker. Integration of Single Ended Primary Inductor Converter (SEPIC) and Flyback converter act as an LED drive. Both these converters are operated in discontinuous conduction mode for supplying LED to achieve the unity power factor. It is compared with conventional SEPIC and Flyback topology. Analysis and simulation of 100 W LED module from 100 VP-P/50 Hz ac supply are analyzed and their results are presented using MATLAB-Simulink.
