Abstract: front page image
(EN)The purpose of the present invention is to provide a wireless power transmission technology capable of achieving high transmission efficiency even in an external environment where there is a possibility of reducing transmission efficiency on the power transmission side. When an increase of a reactance component of a transmission antenna is detected, this power transmission apparatus brings the state of the power transmission antenna close to a resonant state by increasing capacitance of a capacitor connected to the transmission antenna.
(FR)L'objectif de la présente invention est de proposer une technologie de transmission d'énergie sans fil capable d'obtenir une grande efficacité de transmission même dans un environnement externe dans lequel il y a une possibilité de réduction de l'efficacité de transmission sur le côté transmission d'énergie. Lorsqu'une augmentation d'un composant de réactance d'une antenne de transmission est détectée, ledit appareil de transmission d'énergie rapproche l'état de l'antenne de transmission d'énergie d'un état résonant en augmentant la capacitance d'un condensateur connecté à l'antenne de transmission.
(JA) 本発明は、送電側の伝送効率を低下させる可能性がある外的環境においても、高い伝送効率を発揮することができる無線電力伝送技術を提供することを目的とする。 本発明に係る送電装置は、送信アンテナのリアクタンス成分が上昇したことを検出すると、送信アンテナに接続されたコンデンサの容量を増加させることにより、送信アンテナを共振状態に近づける(図6参照)。
