摘　　要：针对传统电镀电源体积大、实现方式复杂以及输出纹波大的特点,提出了一种新型的DC/DC变换器,采用双闭环PWM实时控制方式,具有恒电流和恒电压两种工作方式。用该方法设计了一组9.6 kW电源模块,实验表明,电源输出纹波系数小于1%,效率达到90%。The tradition electroplating power is large and the output ripple is big. This paper provides a circuit scheme that use high-frequency switch power supply. The double close-loop PWM control is adopted in control circuit. The power supply has two kinds of working patter, which are constant current mode and constant voltage mode. A group of 9.6 KW power supply module are designed. According to the experiments, the power output ripple coefficient is less than 1%, and the efficiency is 90%.
