Power feeding is performed in a non-contact manner from a power feeding device (200) to an electrical powered vehicle (100) by resonance of a primary self-resonant coil (240) of the power feeding device (200) and a secondary self-resonant coil (110) of the electrical powered vehicle (100) through an electromagnetic field. The electric power received by the secondary self-resonant coil (110) is rectified by a rectifier (130), and voltage-converted by a DC/DC converter (140) to be supplied to a power storage device (150) A vehicle ECU (180) controls the DC/DC converter (140) such that the voltage between the rectifier (130) and the DC/DC converter (140) attains a target voltage.
Du courant est fourni dun dispositif dalimentation en courant (200) à un véhicule électrique (100) sans aucun contact par résonance dun enroulement primaire à résonance propre (240) du dispositif dalimentation en courant (200) et dun enroulement secondaire à résonance propre (110) du véhicule électrique (100) grâce à laction dun champ magnétique. Le courant reçu par lenroulement secondaire à résonance propre (110) est redressé par un redresseur (130) et converti en tension par un convertisseur continu/continu (140) avant dêtre appliqué à un dispositif accumulateur (150). Une ECU (180) du véhicule commande le convertisseur continu/continu (140) de façon à maintenir la tension entre le redresseur (130) et le convertisseur continu/continu (140) à une valeur cible.
