摘　　要：开关电源作为一种小体积高效率电源有着越来越广泛的应用,但大部分传统开关电源是不可调节的,稳定性较差,为了克服以上缺点,该设计借助STC12C5A60S2单片机采用增量式PI算法对传统开关电源进行优化设计,开发了一款数控开关电源,其电压调节范围为5 V^25 V,最大输出功率为30 W,具有过载保护功能,输出稳定,精度较高。The switching power supply as a small volume,high efficiency power supply is becoming more and more popular,but most of the traditional switching power supply is not adjustable and poor stability. In order to overcome the above shortcomings,a design uses the STC12 C5 A60 S2 MCU and the incremental PI algorithm to optimize the traditional switching power supply,a numerical control switching power supply was developed,its output voltage range is adjustable form 5 V to 25 V. Its maximum output power is 30 W. It has the functions of overload protection,stable output,and high precision.
