摘要针对电阻分压器在直流低电压分压时出现的非线性现象,采用独立影响因素的分析方法,对直流电阻分压器的非线性机理进行了研究。通过分析和实验验证,确定了造成非线性的原因是工作电流的变化导致电阻分压器输出热电势的变化。据此,建立了非线性数学模型,提出了非线性修正方法。利用该方法,±200μV直流电压输出非线性误差小于5nV。

Abstract：Aiming at the nonlinear phenomenon of the resistive voltage divider in the DC low voltage division. The independent influencing factors analysis method is used to study the nonlinear mechanism of the DC resistive voltage divider. Through analysis and experimental verification, make sure that the output thermoelectric potential of the resistive voltage divider changes with the working current, lead to the non-linear divider ratio. According to the above study, the nonlinear mathematical model is founded, and proposing the nonlinear correction method. Using the mentioned method, the maximum non-linear deviation of ±200μV DC voltage output is less than 5nV.

Key words： metrology DC low voltage resistive divider non-linear deviation thermoelectric potential
