摘要
利用单片机系统、D/A转换器和V-I转换电路实现20mA^2000mA数控直流电流源的设计,介绍了设计方案及实施方法。
The design of digital controlled DC source with an output range between 20mA to 2000mA was realized by making use of the single-chip microcomputer system and D/A converter and V-I conversion electric circuit. The design and application were introduced.
