Abstract
(EN)
This power supply device (2), which supplies electric power in a non-contact manner to a power-receiving device (4), is provided with: a substrate (46); a primary coil (48) that is positioned on the substrate (46), and generates flux by means of an alternating current; a cover (44) that is attached to the substrate (46), and covers the primary coil (48); and a motion detection means (14) that detects the motion of an object (50) on the cover (44). Since the motion detection means (14), which is capable of detecting the motion of the object (50) on the cover (44), is provided, the intrusion of the foreign object (50) between the primary coil (48) of the power supply device (2) and a secondary coil belonging to the power-receiving device (4) can be reliably detected.
(FR)
L'invention concerne un dispositif d'alimentation électrique (2) qui distribue de l'énergie électrique d'une manière sans contact à un dispositif de réception d'énergie électrique (4), lequel dispositif (2) comporte : un substrat (46) ; une bobine primaire (48) qui est positionnée sur le substrat (46) et génère un flux au moyen d'un courant alternatif ; un couvercle (44) qui est fixé au substrat (46) et recouvre la bobine primaire (48) ; et un moyen de détection de mouvement (14) qui détecte le mouvement d'un objet (50) sur le couvercle (44). Etant donné que le moyen de détection de mouvement (14), qui est apte à détecter le mouvement de l'objet (50) sur le couvercle (44), est fourni, l'intrusion de l'objet étranger (50) entre la bobine primaire (48) du dispositif d'alimentation électrique (2) et une bobine secondaire appartenant au dispositif de réception d'énergie électrique (4) peut être détectée de façon fiable.
