Description
Few フェライト幅
FeL フェライト長
δA1 延長Rad.
Cd コイル径
Pd パッド径
CW コイル幅
25巻コイル(Φ4mmのリッツ線)、10mm厚のリング
I1 20kHzで23A
コアを形成するフェライトストリップ2の(周りではなく)上方に2つのコイルを配置することによって不所望の背後の磁束経路を排除する別のパッド配置を図5に示す。フェライトは主磁束をコイル(aおよびb)の背後に運び、磁束をコイルが配置される一方の側に確立させる。したがって、コアの下方に設けられるアルミニウム(図5に示さず)は浮遊磁界を遮蔽するだけでよく、ロスは無視できる程度である。パッドの上方で湾曲する理想的な磁束経路を図5に示す。基本長(hz)はパッド長のほぼ2分の1に比例するため、これらの経路は同様に成形された受信パッドとの良好な結合を可能にする。2つの電力パッド間の高結合係数を達成する主要な特徴はパッド間の結合である。パッド間磁束の高さ(Φip)は、コイルaおよびbが相互に隣接する領域において両コイルの幅を調節することによって制御される。この領域は図5で陰を付けられており、コイルaとコイルbとの間の「磁束管」と称する。受信パッドに結合する磁束Φipの一部は相互磁束(ΦM)であるため、磁束管を形成するコイルの部分は理想的にはできる限り長くすべきである。逆に、コイルの残りの長さは、銅を節約し、Racを低減するために理想的には最小限にすべきである。そうする結果、コイルは「D」状となり、2つの上記コイルは背中合わせに配置されるため、本文書でそのパッドはダブルD(DD)構造と称する。
帰路導体がバッキング/シールドプレート16内に形成されるケージ12を使用して遮蔽されるように、同軸巻き線10をコア2に巻き付けた。プレート16はコアの長さ方向端部でコア2の外周を越えて延在し、フランジまたは端部プレート14を形成する。この設計は、最大磁束経路高さおよび結合が達成できるように略円形磁束経路を有することを目的とする。この設計を図6および7に示す。
引き続き、別の変形を提案し、図8および9に示す。この設計は同軸ケージを通過する同軸巻き線(図7および8のダブルD Coaxと同様)ならびにダブルD巻き線(図5を参照して言及したダブルD構造の巻き線aおよびbと類似)を含む。図8および9に示す設計は、ダブルD巻き線を使用して磁界をさらに成形することによって、結合を高め漏れ磁界を低減することを目的とする。
・アルミニウム(すなわち、バッキング)長(最適basin 長=75mm、アルミニウム角度=45度、端プレート長=50mm)。
図12は、図11の設計から生じる磁束密度を示す。バッキング構造(アルミニウムシート材)はアルミニウム構造内の渦電流の誘導を通じて磁界を成形する上で重要な役割を果たす。
