摘要
本文主要讲的是电流型控制PWM芯片UCC3802,在此基础上,研制出了单端反激式开关辅助电源。本文具体讲解了该电源是如何工作的、它都具有哪些功能以及一些相关参数。该辅助电源的好处是结构上不那么复杂,用起来比较方便,输出稳定等,能在只有直流电压供电的情况下使用。
This paper mainly talks about current model control PWM chip UCC3802. On this basis, the paper develops the single-ended flyback type switch auxiliary power. This paper explained how the power supply works, what functions the power supply have, and the related parameter. The advantage of auxiliary power is not complex in structure, is easy to use, and the output is stable, and can be used only powering by DC.
