Therefore, hypothesized the Ea characteristic has a high correlation with the efficiency characteristic at the receiving coil position x even in the case of a multi-coil array type. This time, analyzed |Ea| in detail using a two-coil array system equipped with a relay coil, and clarified how the distribution shape of positional efficiency changes dynamically depending on the drive frequency f. Based on this, determined the |Ea|-x characteristics at five different frequencies and compared them with the η-x experimental characteristics when the secondary side has series resonance and parallel resonance. As a result, demonstrated the distribution shape of the |Ea|-x characteristic has a high correlation with the η-x characteristic._x000D_\n\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌: \u003c\/strong\u003e\u003ca href=\"\/products\/ieej-20250527x14901\"\u003e2025年5月30日電磁環境\/半導体電力変換合同研究会\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌掲載ページ: \u003c\/strong\u003e19-24 p\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別: \u003c\/strong\u003e日本語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ: \u003c\/strong\u003e1,303 Kバイト\u003c\/p\u003e","brand":"IEEJ-P10","offers":[{"title":"冊子印刷（一般価格660円\/会員価格440円） \/ A4 \/ 6","offer_id":46474873929967,"sku":"IEEJ-20250527X14901-001-PRT","price":660.0,"currency_code":"JPY","in_stock":true},{"title":"PDFダウンロード（一般価格330円\/会員価格220円） \/ A4 \/ 6","offer_id":46474901586159,"sku":"IEEJ-20250527X14901-001-PDF","price":330.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-KENKYUKAI_83576c9f-eb33-4499-9e16-70bd74db6c87.png?v=1747906060","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-20250527x14901-001","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
