OVERLAPPING SECONDARY COILS IN A WIRELESS POWER RECEPTION APPARATUS

Abstract:

One innovative aspect of the subject matter described in this disclosure can be implemented in a wireless power reception apparatus. In some implementations, the wireless power reception apparatus may include a ferrite layer including a void. The wireless power reception apparatus may also include a first secondary coil configured to generate first power in cooperation with one or more primary coils of a wireless power transmission apparatus, where at least a portion of the first secondary coil resides in the void of the ferrite layer. The wireless power reception apparatus may also include one or more second secondary coils configured to generate second power in cooperation with the one or more primary coils of the wireless power transmission apparatus, where a portion of the second secondary coil is overlaying the portion of the first secondary coil residing in the void of the ferrite layer.
