摘要
本文提出了一种数字步进式稳压电源的制作,介绍了其硬件设计及仿真和调试过程。该电源以数字电路为核心,将计数器输出的电压控制码通入数模转换芯片,使之输出相应的模拟电压。利用运放电路对输出电压进行校正,使输出电压符合精度要求。该电源可在0～9.9V之间以0.1V步进可调。
This paper presents a digital stabilized voltage power source by step-by-step control. It introduces the design of the hardware, the debugging process and the simulation process. It takes the digital circuit as the core of the circuit. It takes the output control code of decimal counter by the DAC to export the corresponding analog voltage. Then the operational amplifier circuit is used to correct the voltage to make the output voltage accord with the precision demand. This power supply may be adjusted by 0.1V every step between 0 V and 9.9V.
