| 摘 要： | 提出了一种高精度的自激式多路输出稳压开关电源,较以往多路输出开关电源,所用元件极少,其中自激控制部分仅用11个常用元件实现,但是其输出电源精度却很高。而且只需稍做修改,就可将电路中±9V转换为±12V,±15V,其中主回路稍作修改也可改为3.3V/4A精确输出。此电源电路简单,适用范围广。

| Abstract: | A high-precision self-excited switching mode power supply with multi-output has been proposed,compared with the previous multi-output switching mode power supply,the components are used rarely,in which self-excitation control part just use 11 common components.However,the output power accuracy is very high.And with less changes,9 V output of power supply can be converted to 12 V or 15 V output,and the main circuit which do less change can also be changed to 3 .3 V/4 A accurate output.The power supply circuit is simple,and has a wide application scope. |
