数控直流电源
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。

CNC DC Power Supply
Abstract: This issue will introduce a digital DC power supply. The power from the self-regulated power supply, plus or minus NC part of the composition of the digital output display circuit. Among them, the realization of the power supply output voltage regulation, the first thought should be the use of single-chip microcomputer control, can be used single-chip D / A output of the reference voltage regulated power supply, and then through the amplifier and the output voltage control output can be adjusted tune voltage. However, if the above ideas, the entire circuit will become very complicated. Should be convenient to buy as much as possible, the application of simple components to complete the design. Regulated power supply to achieve the simplest way to integrate the use of regulators. If that is the output voltage or output voltage adjustable precision control, the selection of the integrated output voltage adjustable voltage regulator, such as the LM31
