摘要
讨论了一种以ＵＣ３８４２为控制器的ＰＷＭ低压直流开关电源的原理和结构该电源采用离线式控制方式，输出电路相互隔离。
This paper discusses the constitution and principle of a low-voltage DC PWM switching power supply,in which UC3842 is used as controller and outer-line controll mode is adopted.The output circuits are isolated from each other,ensuring high steady precision.
