Research on a High-Efficiency LED Driving Circuit Based on Buck Topology

Abstract

A high efficiency LED (Light Emitting Diode) driver based on Buck converter, which could operate under a wide AC input voltage range (85 V 265 V) and drive a series of high power LEDs, is presented in this paper. The operation principles, power loss factors of the LED driver in this study are analyzed and discussed in detail and some effective ways to… (More)
