Description
前記ロードインピーダンス決定部は、電源共振器と対象共振器との間の距離及び角度のうち少なくとも1つを測定する測定部と、前記測定した距離及び角度のうち少なくとも1つを用いて前記電源共振器の前記ロードインピーダンスの所望の仮想的な値を決定する決定部と、を含む。
前記ロードインピーダンス決定部は、電源共振器と対象共振器との間の距離及び角度の双方を測定する測定部と、前記測定された距離及び角度の双方を用いて前記対象共振器の前記ロードインピーダンスの所望の仮想的な値を決定する決定部と、を含む。
前記ロードインピーダンスを決定する前記ステップは、電源共振器と対象共振器との間の距離及び角度のうち少なくとも1つを測定するステップと、前記測定した距離及び角度のうち少なくとも1つを用いて前記電源共振器の前記ロードインピーダンスの所望の仮想的な値を決定するステップと、を含む。
また逆に、反射波の振幅が基準値超過の場合、相当多量の電力が反射された状態、即ち、相当少量の電力が対象共振器に伝送された状態を意味するから、制御部450は伝送効率が基準値未満のものとしてロードインピーダンスを再び決定するようにロードインピーダンス決定部410を制御する。
また逆に、反射波のパワーが基準値超過の場合、電力が相当多量に反射された状態、即ち、少量の電力だけが対象共振器に伝送され多情体を意味するから、伝送効率が基準値未満のものとしてロードインピーダンスを再び決定するように制御する。例えば、反射波のパワーを測定するように構成されたパワー検出器を用いて反射波のパワーを測定する。
また逆に、反射波の振幅が基準値超過の場合、相当多量の電力がが反射された状態、即ち、少量の電力だけが対象共振器に伝送された状態を意味するから、伝送効率が基準値未満のものとしてロードインピーダンスを再び決定するように制御してもよい。
