Abstract
【解決手段】車両200の共鳴コイル210は、送電装置100の共鳴コイル150と電磁場を介して共鳴することにより、共鳴コイル150から出力される交流電力を非接触で受電する。インバータ240は、共鳴コイル210により受電された交流電力を電磁誘導コイル230から受け、直流に変換して電力線へ出力する。また、インバータ240は、共鳴コイル210から送電装置100の共鳴コイル150へ電力を出力するために、上記電力線から受ける直流電力を交流に変換して電磁誘導コイル230へ出力し、電磁誘導コイル230によって共鳴コイル210へ電力が供給される。

実施の形態2では、車両から外部への送電時にさらに高効率な電力伝送を実現するために、車両において、蓄電装置260の出力電圧を昇圧してインバータ240へ供給可能な構成が示される。ここで、蓄電装置260の出力電圧を昇圧するための装置として、この実施の形態2では、動力出力装置に設けられる走行用の昇圧コンバータが流用される。
実施の形態2では、車両から外部への送電時に蓄電装置260の出力電圧を昇圧してインバータ240へ供給するための装置として走行用の昇圧コンバータ310を流用するものとしたが、この実施の形態3は、電圧コンバータを別途設けるものである。
