一种恒比例调光的谐振型软开关四路LED驱动器
A Resonant Soft-Switching and Four-Channel LED Driver with Fixed Proportion Dimming
摘要
Abstract
In order to cope with color-mixing LED applications,a four-channel LED driver with fixed proportion dimming based on an in-tegrated half-bridge resonant switch network is proposed.The driver adopts a half bridge switch structure,and different resonant capaci-tances are selected to control the dual resonant network,achieving the branch sharing the current within each resonant network and fixed proportion dimming between each resonant network.This structure shares the same inductance,which has the advantage of fewer switc-hing devices.All switches and diodes can achieve soft switching with high efficiency.Finally,a 19 W experimental prototype is built,which verifies the correctness and feasibility of the driver.关键词
