摘要
随着LED技术的不断进步,LED照明将成为未来主流照明技术。功率LED的驱动电源为恒定电流源。在研究现有功率LED驱动电路拓扑结构的基础上,提出了一种改进的电流可调的开关变换器的功率LED驱动电路,仿真和实验证实提出的电路具有电流可调,运行稳定,效率高。
With progress of the technology,LED lighting will be leading lighting technology.Power LED driver is constant current power supply.Based research on power driver topologies,present a improved switch mode power driver circuit with adjusting current,experiment result shown that the presented circuit can adjust current,is stable in operating,and high efficiency.
