摘要
文章所设计的数控直流稳压电源,只使用了数字电路中的振荡器、计数器、译码器、数码管以及模拟电路中的数/模转换器、运算放大器等常见芯片构成的常用电路,实现了数字调节输出电压大小的功能(步进和连续调节均可),且有较高的精度和可靠性。
NC DC power supply is designed in this paper, using only the common chip and circuit in digital and analog circuit,such as oscillator, eounter, decoder, D/A converter, amplifier and other common,etc.Output voltage can be adjusted by numerical control（step and eontinuously）,and has high precision and reliability.
