以单片机为核心的恒流源设计

为了满足测控等领域对于恒流源工作性能的较高要求,设计了一款以单片机为核心的恒流源电流控制系统,指出该系统可以很好地实现2 000 mA范围内的电流控制且电流控制精度非常高,整个设计方案界面简单且可操作性较高,具有一定的友好人机交互特性。

In order to meet the higher requirements for the constant current source performance in the field of measurement and control, a constant current source current control system based on single chip microcomputer is designed. It is pointed out that the system can well realize the current control within the range of 2 000 m A and the current control accuracy is very high. The interface of the entire design scheme is simple and highly operable, and it has certain friendly human-computer interaction characteristics.
