Wireless power transmittal
View Patent ↗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.
1. Apparatus for wireless power transmittal in a coupled inductor system, comprising:
a primary side having a plurality of non-coplanar primary coils, wherein the primary side further comprises transceiver functionality;
a driver circuitry operably coupled to the primary coils and configured to transmit a signal from the driver circuitry to the primary side coils, wherein the primary side coils are arranged on the periphery of a container containing a secondary coil within, and such that signals transmitted from the primary coils are directed toward the interior of the container; and
wherein the apparatus is configured of being inductively coupled to other apparatuses in a daisy chain configuration.
2. The 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 coils.
3. The apparatus according to claim 1 wherein a plurality of primary side coils are connected in series.
4. The apparatus according to claim 1 wherein a plurality of primary side coils are interlaced.
5. The apparatus according to claim 1 comprising the primary coils in three planes.
6. The apparatus according to claim 1 having at least one primary coil configured to lie in a plurality of planes.
7. The apparatus according to claim 1 wherein the primary side coils are arranged in at least two planes such that the secondary coil can be received between them.
8. The apparatus according to claim 1 wherein the primary side further comprises data transmission functionality.
9. The apparatus according to claim 1 wherein the primary side further comprises data receiving functionality.
10. The apparatus according to claim 1 wherein the primary side coils are deployed on a plurality of non-planar surfaces of a container.
11. The apparatus according to claim 1 wherein one or more of the primary side coils are moveable.
12. A system for wireless power transmittal in a coupled inductor system, comprising:
a primary side having a plurality of non-coplanar primary coils arranged on a periphery of a container, wherein the primary side further comprises transceiver functionality;
a 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 disposed within the container;
wherein the secondary side coil is adapted for receiving a power signal from the primary side coil; and
wherein the system is configured of being inductively coupled to other systems in a daisy chain configuration.
13. The system according to claim 12 wherein a plurality of primary side coils are connected in series.
14. The system according to claim 12 wherein a plurality of primary side coils are interlaced.
15. The system according to claim 12 comprising primary coils in three planes.
16. The system according to claim 12 having at least one primary coil configured to lie in a plurality of planes.
17. The system according to claim 12 wherein the primary side coils are arranged in at least two planes such that the secondary coil can be received between them.
18. The system according to claim 12 wherein the primary side coils are arranged on the periphery of the container configured for receiving a secondary coil within, and such that signals transmitted from the primary coils are directed toward the interior of the container.
19. The system according to claim 12 wherein the primary side further comprises data transmission functionality.
20. The system according to claim 12 wherein the primary side further comprises data receiving functionality.
21. The system according to claim 12 wherein the primary side coils are deployed on a plurality of non-planar surfaces of a container.
22. The system according to claim 12 wherein one or more of the primary side coils are moveable.
