Z源谐振型单开关双通道LED驱动器
Z-source Resonant Single-switch Two-channel LED Driver
摘要
Abstract
A novel two-channel light emitting diode(LED)driver is proposed,and its operating principle and characteristics are analyzed in detail.This driver uses a novel Z-source resonant network and an active switch which has the same ground properties as the power supply,and the current balance is automatically realized by balancing capacitors,so its current control is simple.At the same time,owing to the use of Z-source resonant network to transfer energy,the proposed driver has advantages such as soft switching,high efficiency,small volume and low voltage stress.To verify the effectiveness of this driver,a 80 W prototype was built and tested.关键词
