An inductive power supply including multiple tank circuits and a controller for selecting at least one of the tank circuits in order to wirelessly transfer power based on received power demand information. In addition, a magnet may be used to align multiple remote devices with the inductive power supply. In one embodiment, different communication systems are employed depending on which coil is being used to transfer wireless power.

La présente invention concerne une alimentation de puissance inductive comportant une pluralité de circuits oscillants finaux et un contrôleur pour sélectionner au moins un des circuits oscillants finaux afin deffectuer un transfert de puissance sans fil en fonction dune information de demande de puissance reçue. En outre, un aimant peut être utilisé pour aligner une pluralité de dispositifs éloignés avec lalimentation de puissance inductive. Selon un mode de réalisation, différents systèmes de communication sont utilisés dépendant de la bobine utilisée pour le transfert de puissance sans fil.
