摘要
本文分析了一种新型恒流器件的特性和原理,由于采用恒流二极管供流和实现最佳温度补偿获得了非常稳定的输出电流。器件的动态阻抗大,电流温度系数α_H≤10^(-4)/℃,恒定电流I_H在5—500mA范围内具有连续可调等优点。
The characteristics and principles of a new current regulator are analysed- As A result of adopting the current regulator as the current supply and realizing the optirrium temperature compensation, a very stable output current have been obtained. The device not only has large dynamic impedance, current temperature coefficient less than or equal to 10-4/℃. but also has the advantage of continuous adjustability of output current from 1 mA to 500 mA.
