The three-phase WPT system reduces the radiation noise by canceling the noise using pairs of coils placed opposite to each other. However, a magnetic interference among the multiple coils decreases the transmission efficiency due to a circulating current among the primary coils, and the secondary coils in WPT systems with multiple coils. The proposed three-phase WPT system cancels out the effect due to the interference among the six coils on each side. First, the WPT system with the 12 coils is proposed. Then, a canceling condition of the magnetic interference among the coils is mathematically introduced from the voltage equation on the coils. Finally, the proposed WPT system is experimentally demonstrated with the 3-kW prototype. The experimental result shows that the radiation noise at the fundamental frequency is suppressed from 12.2dBμA to 2.1dBμA.本誌: IEEJ Journal of Industry Applications Vol.8 No.4 （2019） Special Issue Ⅰ on “JIASC 2018” Special Issue Ⅱ on “IPEC-Niigata 2018”本誌掲載ページ: 600-607 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/8/4/8_600/_article/-char/ja/
