First, the common-mode current flowing through a cooling fin earth line is studied, and the connection change of the line shows good attenuation of the 1.26MHz resonance component. Second, the common-mode current flowing though the motor earth line with a capacitor is focused upon, and the modified connections of the line to the outside of the input common-mode core achieves fine noise reduction in the range from 500kHz to 1.5MHz. In such cases, the existing input common-mode core is utilized to establish the impedance, which is efficient in both the noise reduction and the countermeasure cost reduction. Finally, a current simulation model which is paid attention to the AM radio frequency range is examined with the measured impedance data of the VVVF inverter system. The currents flowing thorough the cooling fin earth line and the motor earth line is simulated, and these simulated currents show good agreement with the measured one.本誌: 電気学会論文誌D（産業応用部門誌） Vol.139 No.5 （2019） 特集：平成30年産業応用部門大会本誌掲載ページ: 495-502 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejias/139/5/139_495/_article/-char/ja/
