Abstract
Description
別の実施例において、たとえば電気自動車に水平に取り付けられているレシーバーパッドまたはピックアップパッドのコイルの配置は、磁束の発生器(水平向きのトランスミッターパッド)に関してピックアップパッドを長手方向に向けられた磁束の第1の方向(すなわち、磁心14に対して平行方向で図面ではX軸方向)に対しピックアップパッドを敏感にする。ずれがある場合のレシーバーの磁気的な結合を改善するために、固定されたトランスミッターに対して望ましくは垂直である磁束の第2の成分に敏感な「第2の」コイルを配置することができる。
図11に戻り、コイル17に対する巻き線配置が模式的に説明されている。この実施例では、コイル17の個別の巻きはパッドの端部に比較してパッドの中心に近いところの各巻き線の終わりで拡大されている。したがって、コイル17はそれぞれ非対称であって、コイルの巻き線の組み合わせは、磁極領域と磁極領域の間ではパッドの周辺に比べて、広くなっている。この実施例は、磁極領域11および12(と磁束パッドの前面を越えて延びる大きい磁束の広がり)をより大きい間隔にすることを可能にしている。磁極領域11および12の間隔は、磁極領域11および12の狭い周縁部上と磁極領域と磁極領域の間の磁気パイプの中央の箇所に対してフラットな周縁部上とに巻かれた、楕円または長方形の断面のリッツ線を用いることでより大きくすることができる。
実際には、パッドのターミナルの電圧は安全が保持できないレベルに到達しないようにするのが望ましい。したがって、いくつかの実施例では、パッドのターミナルからみたインダクタンスを低下するように、コンデンサがパッドの内部に巻き線に直列に加えられてもよく、これらのターミナルで望ましい限度内(たとえば、300〜400ボルト)になるように電圧を制御してもよい。そうしないと、ターミナル電圧は数KVに及ぶことがあるため、望ましいとはいえず、また安全が保持できない恐れもある。コンデンサは装置のどこか配置しやすい場所の近くに巻き線と直列に配置することができる。したがって、いくつかの実施例において、ひとつ以上のコンデンサがパッドの筐体の内部のターミナルポイントに巻き線と直列に配置することができる。他の実施例において、一つのコイルの内部電圧が高くなりすぎるような場合は、コンデンサを巻き線に沿って分けて配置し、巻き線をいくつかの適当なセクションに分けて、直列に接続することができる。
