The operating principle is described using the coupled mode theory. This study specifically focuses on the coupling situation, from strong coupling to incomplete PTS matching. The voltage amplitude in the receiver circuit increases because the PTS condition is completely preserved. However, it is difficult to initiate oscillation as there is a trade-off between the voltage amplitude and highly responsive oscillation in PTS-WPT for gain in the negative resistance regime. By enhancing the white noise signal, highly responsive oscillation is achieved at a high voltage and low gain. This study focuses on the enhancement of white noise for negative resistance for WPT. The proposed enables achieving to earlier stable oscillation with a high power supply.本誌: IEEJ Journal of Industry Applications Vol.10 No.2 （2021） Special Issue Ⅰ on “Motion Control and its Related Technologies” Special Issue Ⅱ on “Advanced Power Electronics Technologies”本誌掲載ページ: 254-261 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/10/2/10_20006504/_article/-char/ja/ Show more
