摘要
先对开关电源的工作原理进行了介绍,并对其控制芯片进行详细说明,然后对主电路和硬件进行了合理的设计以及相关参数的计算,最后对设计的开关电源进行了测试。实验结果表明,本设计的开关电源具有良好的稳压作用,精度可以达到83.3%。
In this paper,it first introduces the principle of switching mode power supply. And then the control chip is introduced in detail. The main circuit and hardware is designed and parameters are also calculated. Finally,the performance of the positive pulse width conversion is tested. The tested result shows that the design has good voltage stabilization and its precision can reach 83. 3%.
