| Abstract: | ： 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. |
