Abstract
The present application provides a wireless power transfer system including a transmitter and at least one receiver, and also provides transmitters and receivers for such systems. The transmitter includes a driver coil and a transmitter coil magnetically coupled to each other and arranged along a plane, the driver coil and the transmitter coil being tuned to resonate at differing frequencies. The receiver includes a load coil and a receiver coil magnetically coupled to each other and arranged along a plane, the load coil and the receiver coil being tuned to resonate at differing frequencies. The driver coil and the transmitter coil of the transmitter, and the load and the transmitter coil of the receiver are strongly magnetically coupled to each other. The transmitter and the receiver are magnetically coupled to each to effectuate wireless power transfer from the transmitter to the receiver.
