摘　　要：利用脉宽调制集成控制电路ＬＭ３５２５研制出一种适用于小型程控交换机的ＤＣ－ＤＣ、ＡＣ变换器，对电路的工作原理进行了分析并给出了实验结果．In this peper, PWM and IC-LM3525 were used to make DC-DC.AC converters,which are adaptable to the small-sized program controlled exchanger. The working principle of the circuits were analysed and the experiment results were provided too.

关 键 词：脉宽调制 电路 开关电源 程控交换机
