Furthermore, in the future, the primary coil area tends to broaden, including support for multiple devices. On the other hand, in the primary coil of an area that is excessively wide relative to the secondary coil, magnetic flux is generated also in an area not related to power supply by the exciting current, causing problems such as an increase in noise and standby power. As a solution, a spot feeding system has been proposed in which a plurality of primary coils are arrayed and only the primary coil under the secondary coil is excited. However, in this method, when the secondary coil is small, there is a problem that the received voltage drops more than the other positions on the side portions of the adjacent primary coils. The author has studied how the receiving voltage becomes constant on the entire surface of the coil array and can use the gradient winding coil to stabilize the receiving voltage on the whole surface of the coil array without increasing the thickness of the primary coil was confirmed.\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\u003e1,052 Kバイト\u003c\/p\u003e","brand":"IEEJ-PDF","offers":[{"title":"PDFダウンロード（一般価格330円\/会員価格220円） \/ A4 \/ 6","offer_id":46393310249199,"sku":"IEEJ-SPC18042MD18042-PDF","price":330.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_3069dd83-dfc4-4a85-aa76-220836ae50a9.png?v=1744687637","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-spc18042md18042","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
