Conducted susceptibility diagnosis of vehicle electronic circuit using mixed-mode S-parameter method

In this paper, the conducted susceptibility of vehicle electronic circuit to external common- mode disturbances was studied using the mixed-mode S-parameters method. The proposed method uses the common-to-differential mode conversion to account for conducted susceptibility. According to the experimental results, the correlation between the BCI test and the mixed-mode S-parameters method is in good agreement for predicting the immunity weakness.
