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.
