摘要

本文提出了一种等效串联电阻(ESR)测量方法，该方法涉及对电解电容器施加短电压脉冲。在该方法中，通过选取适当的点对电容器的充电曲线进行线性插值得到ESR的值。为了验证我们的测量方法，我们将实际实验得到的值与BK Precision 891台式LCR仪提供的结果进行了比较。经过比较，我们发现实验结果与LCR仪提供的值非常接近，最大相对误差小于12%。

In-circuit ESR Measurement Method for Electrolytic Capacitors

This paper presents an Equivalent Series Resistance (ESR) measurement method that involves the application of short voltage pulses to an electrolytic capacitor. In the proposed method, the value of the ESR is given by linear interpolating the charging curve of the capacitor taking several appropriate points. In order to validate our measurement method, we compared the values obtained from the practical experiments with the results provided by a BK Precision 891 Bench LCR Meter. After comparison, we found that the experimental results are very close to the values provided by the LCR Meter, the maximum relative error being less than 12%.
