Description
これら給電コイルL10aおよび給電コイルL10bを構成する巻線としては、銅、アルミニウムなどの金属ワイヤを多数本撚り合わせたリッツ線が挙げられる。また、給電コイルL10aおよび給電コイルL10bの巻数は、所望の電力伝送効率に基づいて適宜設定される。なお、給電コイルL10aと給電コイルL10bは、コイルに流れる電流によって発生する磁束量を等しくするという観点から、同材質の金属ワイヤから構成し、同じ巻数とするのが好ましい。
次に、図6を参照して、本発明の第1実施形態の変形例に係る非接触電力伝送装置の全体構成について説明する。図6は、図2に示した本発明の第1実施形態に係る非接触電力伝送装置における給電コイルユニットと選択部の一部拡大図に相当する、本発明の第1実施形態の変形例に係る非接触電力伝送装置の給電コイルユニットと選択部の一部拡大図である。本変形例では、第1実施形態に係る非接触電力伝送装置S1における給電コイルユニットL1に代えて給電コイルユニットL30を備えている点において相違し、その他の構成は本発明の第1実施形態に係る非接触電力伝送装置S1と同様である。以下、第1実施形態と異なる点を中心に説明する。
次に、図8を参照して、本発明の第2実施形態に係る非接触電力伝送装置の全体構成について説明する。図8は、図2に示した本発明の第1実施形態に係る非接触電力伝送装置における給電コイルユニットと選択部の一部拡大図に相当する、本発明の第2実施形態に係る非接触電力伝送装置の給電コイルユニットと選択部の一部拡大図である。本実施形態では、本発明の第1実施形態に係る非接触電力伝送装置S1における給電コイルユニットL1に代えて給電コイルユニットL40を備えている点において相違し、その他の構成は本発明の第1実施形態に係る非接触電力伝送装置S1と同様である。以下、第1実施形態と異なる点を中心に説明する。
