摘 要：本课题将介绍一种数控直流电源。该电源由自制稳压电源、加减数控部分、数字输出显示电路组成。其中，实现稳压电源的输出电压调节，首先想到的应是利用单片机控制，可以经过单片机用过D/A输出稳压电源的基准电压，再通过放大器和输出电压调整管输出可调电压。但如果按上面的思路，整个电路将变得很复杂。则应尽可能采用方便买到、应用简捷的元器件来完成设计。实现稳压电源最简单的方式就是采用集成稳压器。如果是输出电压可调或输出电压精确控制，则选用输出电压可调的集成稳压器，如正电压输出的LM317和负电压输出的LM337.在以LM317为基本稳压电路的基础上，附加电压调节电路、数字电压显示电路即可完成设计任务。

Numerical control dc power supply
This task will be to: pick a nc dc power supply. The power of homemade manostat, add CNC parts, digital output display circuit. Among them, realize the output voltage regulator, the first thought of using single-chip microcomputer control shall be used by MCU, D/A benchmark voltage output voltage stabilizer, again through the amplifier output voltage adjustment and adjustable voltage output tube. But if the circuit, it will be very complicated. It should be easy to buy, the application of components to finish design simplicity. Realizing manostat the simplest way is using integrated stabilizer. If the output voltage is adjustable output voltage or accurate control, chooses the adjustable output voltage regulator, such as integrated LM317 output voltage is the voltage output and negative LM337. In LM317 for basic voltage circuit, and on the basis of digital circuit, additional voltage regulation voltage display circuit can complete design task.
