Although the loosely coupled inductor is usually designed by adjusting the coupling coefficient in order to meet the design specifications, the coupling coefficient is saturated by the fringing fluxes in the central leg and the external leakage fluxes in the case of the EE or EI magnetic core structures. It is a matter of concern that these fluxes are causes of electromagnetic induced noise and reduction in the downsizing performance. To solve this problem, this paper proposes a short-circuited winding for the coupled inductor in order to reduce the external leakage flux in the windings. The effectiveness of the coupled inductor with a short-circuit ring is evaluated with experimental tests.本誌: IEEJ Journal of Industry Applications Vol.5 No.2 （2016） Special Issue on Motion Control and its Related Technologies本誌掲載ページ: 174-175 p原稿種別: 研究開発レター／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/5/2/5_174/_article/-char/ja/
