Description
以下、第1実施形態における本発明の給電システムを図1及び図2を参照して説明する。図1は、本発明の給電システムの一実施形態を示すブロック図である。図2は、第1実施形態における図1に示す給電システムの斜視図である。図1に示すように、給電システム1は、給電設備に設けられる給電部2と、車両に搭載された受電部3と、を備えている。
次に、第2実施形態について図3を参照して説明する。第1実施形態と異なる点は、受電部3側のフェライト37を廃止して、代わりに給電部2側にフェライト27を設けた点である。このフェライト27は、給電側シールドケース25外に設けられ、平板状に設けられている。フェライト27は、第1実施形態と同様に、給電時における給電側、受電側共鳴コイル23、31の離隔方向に対して垂直に配置されている。この場合も第1実施形態と同様に、給電側共鳴コイル23により発せられた磁界のうちシールドケース25、36外から漏れた漏洩磁界が、シールドケース25、36外に設定されたフェライト27により吸収されるため、大電力の給電システムであっても十分に電磁漏洩を防止できる。
