Under these conditions, instead of forming a hysteresis loop, the magnetic material in the inductor forms minor loops on the BH plane corresponding to the current flow. The area of these minor loops represents the iron loss per unit volume. The shape and area of the minor loops vary depending on the values of the rectangular voltage waveform and DC current, as well as the position of the loop on the BH plane. This paper proposes a measurement procedure to accurately measure and analyze the position and shape of minor loops by controlling the current flowing through the inductor in a half-bridge inverter.本誌: 電気学会論文誌D（産業応用部門誌） Vol.144 No.12 （2024）本誌掲載ページ: 808-814 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/144/12/144_808/_article/-char/ja/
