输出双路可调开关电源

Output Dual Channel Adjustable Switching Power Supply

文中介绍了开关电源使用一个电位器控制两路不同电压范围输出线性调节的工作原理,给出了具体设计过程、实际操作和在实际中的运用,得出了电位器设在输入级,只需利用双光耦实现电平隔离传输,完成电位器(或电平)对输出电压进行调节的结论。此方法亦可推广应用到多路可调输出。

In this paper,the operation principle of switching power supply using apotentiometer to control the output of two different voltage range is introduced,and the specific design process,practical operation and application in practice are given,also the potentiometer is set in the input stage,Just realize the level of the isolation transmission using double coupling,and complete the potentiometer(or level)to adjust the output voltage of the conclusion.This method can also be applied to multi output adjustable output.
