PROBLEM TO BE SOLVED: To provide a wireless power supply system capable of simultaneously conducting wireless power supply to a plurality of appliances and different appliances.SOLUTION: A plurality of primary coils L1 are arranged in the same surface, and a power supply module M is provided for each primary coil L1. Each power supply module M receives an appliance authentication signal ID and an excitation request signal RQ from the appliances E through signal receiving antennas AT1 mounted at positions adjacent to the primary coils L1. A system controller 8 outputs a permission signal EN permitting the continuous excitation of the primary coils L1 to the power supply modules M outputting the appliance authentication signal ID and the excitation request signal RQ in each power supply module M. When the appliances E are placed on a placing surface, only the primary coils L1 positioned just under the appliances E are excited continuously without the continuous excitation of the whole primary coils L1 arranged on the same surface. Consequently, a plurality of appliances E are placed simultaneously, and can be supplied with electricity at the same time. |
