The proposed model can be used to calculate the small-signal characteristics of CMIs over a wide band of frequencies by substituting the stray capacitance values in the model are considering the frequency dependence of the complex permeability. The common-mode (CM) impedances of the fabricated manganese zinc-ferrite and nanocrystalline CMIs are measured using an impedance analyzer to validate the proposed model. Comparisons between the results of the measured and calculated CM impedances for the fabricated CMIs show that the proposed model enables the calculation of the CM impedances of CMIs over a wide frequency range from 1kHz to 100MHz.本誌: IEEJ Journal of Industry Applications Vol.11 No.3 （2022）本誌掲載ページ: 514-521 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/11/3/11_21010626/_article/-char/ja/ Show more
