Investigation on single stage ac dc pfc converter topologies for led application

Abstract

Increasing power consumption, a growing population, and the depletion of energy supplies are all contributing to a global energy crisis. An alternative source of energy generation and other energy-saving options may be used to address this. According to research, lighting uses one-fifth of all energy. Due to its potential to replace outdated lighting technologies like incandescent bulbs and compact fluorescent lamps, Light-Emitting Diode (LED), technology has recently gained popularity due to its longer life, compact design, and higher efficacy. An efficient longer-life, high input power factor, and low input current harmonics distortion LED driver which could operate with 110 Vrms to drive a 30 W LED bulb are mainly presented in this work. newline
