Abstract
Wireless power transmittal apparatus and systems are disclosed in which transmitter and receiver inductors, or coils, are coupled in configurations for wirelessly transferring power and/or data among them. In preferred implementations, a plurality of non-coplanar primary side coils are provided in power transmittal apparatus for transmitting power, or power and data.
Claims20
An apparatus comprising:
- a first planar primary coil disposed on a structure in a first plane;
- a second planar primary coil disposed on the structure in a second plane that is different from the first plane;
- and
- driver circuitry operably coupled to the first primary coil and the second primary coil and configured to selectively activate one or both of the first primary coil and the second primary coil as a function of a location of a secondary coil external to the structure and to transmit power or data as a function of the selection.

A system for wireless power transmittal in a coupled inductor system, comprising:
- a first primary coil disposed on a first structure in a first plane;
- a second primary coil disposed on a second structure in a second plane;
- first driver circuitry operably coupled to the first primary coil and second driver circuitry operably coupled to the second primary coil and configured to selectively cause a power signal or a data signal to be transmitted from one or both of the first primary coil and the second primary coil;
- a secondary side coil external to the first structure and the second structure;
- and
- wherein the secondary side coil is configured to receive the power signal from the first primary coil and the second primary coil.
