一种新型高效LED驱动电源设计
A novel high-efficient power supply for LED
摘要
Abstract
A novel high-efficient power supply for LED was designed in this paper.The double feedback control loop was adopted to realize the control for constant current and stable voltage.This power supply was based on the isolated Flyback converter with former stage power factor correction circuit to improve the power factor.The superfine crystal core was employed to make the transformer get smaller,which could reduce the whole volume of the power supply for LED.The experimental results of the designed power supply for LED show that both the power factor and the precision for constant current and stable voltage are increased.And the conversion efficiency is improved while the whole volume of power supply is reduced.关键词
