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.

Claims

1. Apparatus for wireless power transmittal in a coupled inductor system, comprising:

a primary side having a plurality of non-coplanar primary coils; and

driver circuitry operably coupled to the primary coils, whereby a signal may be transmitted from the driver to emerge through the primary side coils.

2. Apparatus according to claim 1 further comprising a secondary side having a secondary side coil;

wherein the secondary side coil is adapted for receiving a power signal from the primary side coil.

3. Apparatus according to claim 1 wherein a plurality of primary side coils are connected in series.

4. Apparatus according to claim 1 wherein a plurality of primary side coils are interlaced.

5. Apparatus according to claim 1 comprising primary coils in three planes.

6. Apparatus according to claim 1 having at least one primary coil configured to lie in a plurality of planes.

7. Apparatus according to claim 1 wherein the primary side coils are arranged in at least two planes such that a secondary coil may be received between them.

8. Apparatus according to claim 1 wherein the primary side coils are arranged on the periphery of a container suitable for receiving a secondary coil within, and such that signals transmitted from the primary coils are directed toward the interior of the container.

9. Apparatus according to claim 1 wherein the primary side further comprises data transmission functionality.

10. Apparatus according to claim 1 wherein the primary side further comprises data receiving functionality.

11. Apparatus according to claim 1 wherein the primary side further comprises transceiver functionality.

12. Apparatus according to claim 1 wherein the primary side coils are deployed on a plurality of non-planar surfaces of a container.

13. Apparatus according to claim 1 wherein one or more of the primary side coils are moveable.

14. A system for wireless power transmittal in a coupled inductor system, comprising:

a primary side having a plurality of non-coplanar primary coils;

driver circuitry operably coupled to the primary coils, whereby a signal may be transmitted from the driver to emerge through the primary side coils; and

a secondary side having a secondary side coil;

wherein the secondary side coil is adapted for receiving a power signal from the primary side coil.

15. A system according to claim 14 wherein a plurality of primary side coils are connected in series.

16. A system according to claim 14 wherein a plurality of primary side coils are interlaced.
