摘要
为了LED电源的推广使用,设计了以常用的反激式变换器为核心的LED电源。本文通过设计出来一种4.2W的LED电源电路,具体介绍了利用反激式变换器拓扑成LED电源的方法,并且对各个元件的参数选择进行了说明,特别对变压器的参数进行了详细的计算。实验结果完全达标,说明了设计方法的正确性。
： In order to promote the use of LED power supply designed to common flyback converter as its core LED power. This paper designed a LED power supply circuit of 4.2W, specifically describes the use of a flyback converter topology LED power method and parameters of each component are described, in particular, the parameters of the transformer for a detailed calculation. Experimental results fully met, illustrate the correctness of the design method.
