资料介绍

针对传统的电路特征参数提取方法不能直接提取Buck电路电解电容的特征参数的问题,提出了基于时域电路分析法和频域电路分析法的特征参数提取方法,应用于Buck电路的电解电容特征参数的提取中,并且和Buck电路等效模型参数提取法进行对比.实验结果证明,文章所提出的时域电路分析法和频域电路分析法能对电解电容的参数进行准确地提取,而且相对误差较小.

In order to solve the problem that the traditional circuit characteristic parameter extraction method can not directly ex-tract the characteristic parameters of Buck circuit electrolytic capacitance, a method based on time -domain circuit analysis method and frequency-domain circuit analysis method is proposed to extract the characteristic parameters. It is applied to the extraction of characteristic parameters of electrolytic capacitance of Buck circuit and compared with the method of extracting equivalent model pa-rameters of Buck circuit. The experimental results show that the proposed time-domain circuit analysis and frequency-domain circuit analysis can accurately extract the parameters of the electrolytic capacitance, and the relative error is small.
