摘　　要：LED的快速发展,使得LED驱动电源的设计成为LED关注热点。由于LED的物理特性,决定了驱动电源应满足使LED正常发光的各种要求。设计了一款无IC控制的单端反激式LED驱动电源,主要介绍了反激式变压器的设计计算。该驱动电源电路结构简单,可驱动30颗LED灯珠,经测试效率可达88%,纹波电流仅为1.07%,可作为室内外照明应用。With the rapid development of LED,the designer of LED’s power supply became the hot spot. As for the physical characteristics of LED, determined the requirement of normal light was met of the power supply. A single-ended flyback converter without IC was designed. And the design and calculation of the flyback transformer were introduced. A simple structure was owned by this drive circuit, 30 LED lamp was driven. Its conversion efficiency was up to 87%,ripple current only 1.07%,and it could be applied in and outside general lighting.
