摘要
本文介绍一种基于单片机的数控直流电源的设计。该系统主要由单片机、D/A转换器、功率放大电路及键盘显示电路等构成。该电源能够提供-9.9^+9.9V,步进为01V的直流电压,电压的预期值和实测值均可由LED显示。具有结构简单合理的优点。
This paper introduces a control based on single chip design of the dc power supply. This system mainly consists of SCM, D/A converter, power amplifier circuit and keyboard display circuit, etc. This power can provide - 9.9 - ＋ 9.9 V, stepping 01V for de voltage, the expected value and the voltage can be measured by the LED display. This system has the advantages of simple structure is reasonable.
