Description
まず、図1〜図4を参照して第1参考形態の非接触給電装置の構成について説明する。なお、図中における前後方向、左右方向及び上下方向は、車両における方向を示すものである。
次に、第2参考形態の非接触給電装置について説明する。第2参考形態の非接触給電装置は、第1参考形態の受電側パッドの大きさが送電側パッドより大きいのに対して、受電側パッドの大きさが送電側パッドより小さくなるようにするとともに、それに伴って補助パッドの大きさを変更したものである。
次に、第3参考形態の非接触給電装置について説明する。第3参考形態の非接触給電装置は、第2参考形態の送電側パッドの巻線が矩形状であるのに対して、これを円形状にするとともに、補助パッドの構成を変更したものである。
次に、第4参考形態の非接触給電装置について説明する。第4参考形態の非接触給電装置は、第3参考形態の補助パッドが巻線とキャパシタとによって構成されるのに対して、これにコアを追加したものである。
次に、第5参考形態の非接触給電装置について説明する。第5参考形態の非接触給電装置は、第2参考形態の受電側パッドの巻線が矩形状であるのに対して、これを円形状にするとともに、補助パッドの構成を変更したものである。
次に、第1実施形態の非接触給電装置について説明する。第1実施形態の非接触給電装置は、第1参考形態の補助パッドに対してICタグを設けるとともに、ICタグの出力する情報に基づいて送電回路が動作するようにしたものである。
次に、第6参考形態の非接触給電装置について説明する。第6参考形態の非接触給電装置は、第1参考形態の非接触給電装置が、1つの送電回路で、1つの送電側パッドに電圧を印加するのに対して、1つの送電回路で、巻線の大きさ及び形状が同一である複数の送電側パッドのうちから1つを選択して電圧を印加するようにしたものである。
第6参考形態によれば、非接触給電装置7は、2つの非接触給電パッド71A、71Bと、送電回路70と、接続切替え回路73とを備えている。非接触給電パッド71A、71Bは、大きさ及び形状が同一である送電側パッド710A、710Bを有している。接続切替え回路73は、非接触給電パッド71A、71Bの送電側パッド710A、710Bのうちいずれか1つを送電回路70に接続する。そのため、送電回路を増やすことなく、非接触給電パッド71A、71Bの送電側パッド710A、710Bに電圧を印加することができる。しかも、送電側パッド710A、710Bは、大きさ及び形状が同一である。そのため、送電側パッド710A、710Bいずれにも最適な電圧を印加することができる。
