摘　　要：提出1种新型双通道发光二极管LED(light emitting diode)驱动器,并详细分析了其工作原理和特点。所提驱动器使用1种新型Z源谐振网络和1个与电源共地的有源开关结构,并利用平衡电容自动实现电流均衡,因此其电流控制非常简单。同时由于利用Z源谐振网络传递能量,该驱动器具有软开关、效率高、体积小、电压应力较低等优势。为验证所提驱动器的有效性,研制了1台80 W的实验样机进行测试。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.
