The homogenization method replaces fine-structured material such as multi-turn coils, soft magnetic composite and laminated iron sheets with uniform material with complex permeability. The present method reduces the FE equation including the complex permeability to a circuit equation for small variables which can be solved with small computational cost. The present method is effective for time-domain analysis and makes it possible to consider magnetic saturations.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.140 No.2 （2020） 特集：令和元年電力・エネルギー部門大会本誌掲載ページ: 134-139 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/140/2/140_134/_article/-char/ja/ Show more
