一种采用数字信号控制的高稳定性恒流器件

A High-stability Current Regulator Based on Digital Signal Control

本文介绍一种数控恒流器件，其主电路具有数模转换功能。器件采用模块结构，低功耗，小体积，具有优良的电性能。文中还从理论上讨论了器件的设计思想和应用，并给出了器件测试结果。

This paper introduces a digital control constant current device, its main circuit includes the D/A transformation function. New-made current regulators adoptes the structure of module, low power consumption, reduced size and better performance. In the paper, the designing thought and applications of modular constant--current circuits is proposed for the new device, and the experiment results is given.
