図2に本実施形態の送電装置10、送電制御装置20、受電装置40、受電制御装置50の構成例を示す。図1(A)の充電器500などの送電側の電子機器は、図2の送電装置10を含む。また携帯電話機510などの受電側の電子機器は、受電装置40と負荷90(本負荷)を含むことができる。そして図2の構成により、例えば1次コイルL1と2次コイルL2を電磁的に結合させて送電装置10から受電装置40に対して電力を伝送し、負荷90に対して電力を供給する無接点電力伝送(非接触電力伝送)システムが実現される。
図3に、本実施形態により実現される無接点電力伝送の処理シーケンスの概略を模式的に示す。
さて、無接点電力伝送が普及すると、受電側の2次コイルとして様々なタイプのものが市場に出回ることが予想される。即ち、受電側である携帯電話機等の電気機器の外形・サイズは様々であるため、これに応じて、電子機器の受電装置に内蔵される2次コイルの外形・サイズも様々なものになる。また各電子機器が必要とする無接点電力伝送の電力量(ワット数)や出力電圧も様々であるため、これに応じて2次コイルのインダクタンス等も様々なものになる。
次に本実施形態の動作について図7(A)〜図11(C)を用いて詳細に説明する。
図12に本実施形態の詳細な構成例を示す。なお以下では図2で説明した構成要素については同符号を付し、適宜、その説明については省略する。
次に、送電側と受電側の動作の詳細について図14、図15のフローチャートを用いて説明する。
図16(A)において、コイルの特性を表すコイルパラメータとしては、コイルの内径、外径、コイル面積などがある。ここでは、1次コイルについては、コイルパラメータが固定された1つのコイルを用意し、2次コイルについては、コイルパラメータが異なる様々なコイルを用意して、測定を行っている。
