Description
[構成等]
図1は、第1の実施形態における電力伝送システム10が置かれる環境の一例を示す模式図である。電力伝送システム10は、送電装置100、受電装置200、及びコイルCLを備える(図2参照)。送電装置100は、受電装置200に対して、複数のコイルCLを介して、磁気共鳴方式に従ってワイヤレス(無接点)で電力伝送する。配置されるコイルCLの数は、n個であり、任意である。
まず、第1のシミュレーションについて説明する。
第2のシミュレーションでは、主に第1のシミュレーションと異なる箇所について説明し、第1のシミュレーションと同様の事項については、説明を省略又は簡略化する。
このように、送電装置100は、水中において、受電コイルCLBを有する受電装置200に電力を伝送する。送電装置100、磁界を介して受電コイルCLBに電力を伝送する送電コイルCLAと、所定の周波数(例えば11kHz~12.3kHz、8kHz~8.5kHz)の交流電力を送電コイルCLAへ送電するドライバ151と、送電コイルCLAに接続されると共に、送電コイルCLAと共に共振する共振回路152を形成するコンデンサCAと、を備える。所定の周波数は、送電コイルCLAのQ値(例えばQ1)及び受電コイルCLBのQ値(例えばQ2)の相乗平均値(例えばQ3)が最大となる周波数fq13,fq23と、送電コイルCLAのQ値及び受電コイルのQ値が同値となる周波数fcp1,fcp2と、の間のいずれかの周波数である。
以上のように、本開示における技術の例示として、第1の実施形態を説明した。しかし、本開示における技術は、これに限定されず、変更、置き換え、付加、省略などを行った実施形態にも適用できる。
