Abstract

　電源回路に接続した送信アンテナ（１）から角周波数ωの交流電力を空間を隔てた受信アンテナ（２）に良い効率で伝送し負荷回路に伝送する誘導電力伝送回路が、両端を容量（Ｃ１）でつないだ、実効的自己インダクタンスがＬ１の送信アンテナ（１）の中間のポート１（Ｐ１）に電源回路を直列に接続した回路と、両端を容量（Ｃ２）でつないだ、実効的自己インダクタンスがＬ２の受信アンテナ（２）の中間のポート２（Ｐ２）に負荷回路を直列に接続した回路を有し、アンテナ同士の電磁誘導の結合係数ｋと任意の値の位相角βに関して、前記角周波数ωをＬ２×Ｃ２×（１＋ｋ・ｃｏｓ（β））の値の逆数の平方根にして、前記電源回路の出力インピーダンスを約ｋωＬ１・ｓｉｎ（β）にし、前記負荷回路の入力インピーダンスを約ｋωＬ２・ｓｉｎ（β）にすることで得られる。また、回路のインピーダンスを変換するインピーダンス変換回路が得られる。
