Abstract
(EN) [OBJECT] There is provided a wireless power transmission system capable of transmitting power efficiently even when there is an obstacle or the like. [ORGANIZATION] A power transmission device has a first and a second electrode (111, 112), a first and a second connection line (115, 116), and a first inductor (113, 114). A power reception device has a third and a fourth electrode (121, 122), a third and a fourth connection line (125, 126), and a second inductor (123, 124). At least one of the first to the fourth electrode is housed in a conductive casing (310, 320) having an opening corresponding to an opposing electrode, and a resonance frequency of a power transmission coupler constituted of the first and the second electrode and the first inductor (113, 144) and a resonance frequency of a power reception coupler constituted of the third and the fourth electrode and the second inductor (123, 124) are set to be substantially equal.
(FR) Le problème décrit par la présente invention est de fournir un système de transmission d'énergie sans fil pouvant transmettre de l'énergie de façon efficace même en présence d'obstacles. Pour ce faire, la présente invention concerne un dispositif de transmission d'énergie comprenant une première et une deuxième électrode (111, 112), une première et une deuxième ligne de connexion (115, 116), et des premiers inducteurs (113, 114). L'invention concerne également un dispositif de réception d'énergie comprenant une troisième et une quatrième électrode (121, 122), une troisième et une quatrième ligne de connexion (125, 126), et des seconds inducteurs (123, 124). Au moins une des électrodes de la première à la quatrième est logée dans un boîtier conducteur (310, 320) doté d'ouvertures correspondant aux électrodes se faisant face. La fréquence de résonance d'un coupleur de transmission d'énergie composé de la première électrode, de la seconde électrode et des premiers inducteurs (113, 114) et la fréquence de résonance d'un coupleur de réception d'énergie composé de la troisième électrode, de la quatrième électrode et des seconds inducteurs (123, 124) sont définies de manière à être sensiblement identiques.
