基于单片机的ATX电源直流稳压设计

DC Voltage Stabilizing Design of ATX Power Supply Based on Single Chip Microcomputer

通过键盘实现对电压的可调,以实现对废弃ATX电源的再利用,以达到环保的目的。以STC15W408AS单片机为核心,通过四位数码管显示设置以及输出电压。其主要包括ATX电源,AD电压采集,AD键盘,LED数码管显示等。最终将采集到的电压值在LED数码管上显示出来,按键可调节电压值。废弃ATX电源可再利用。

To realize the adjustable voltage through the keyboard,it aims to realize the reuse of the waste ATX power source,so as to achieve the purpose of environmental protection.The STC15W408AS microcontroller was used as the core,and the output voltage was set through four digital tube display.It mainly includes ATX power supply,AD voltage acquisition,AD keyboard,LED digital tube display and so on.The collected voltage value is finally displayed on the LED digital tube,and the button can adjust the voltage value.The waste ATX power source can be reused.
