Wireless power transfer systems and methods
First Claim
1. A transmitter that transmits wireless power, comprising:
- a radio frequency antenna configured to transmit wireless power;
a magnetic inductive coil configured to transmit wireless power;
a plurality of drive loops;
one or more switches connected to the plurality of drive loops and the radio frequency antenna; and
a controller configured to connect or disconnect one or more of the plurality of drive loops using the one or more switches and connect or disconnect the radio frequency antenna using the one or more switches, wherein the controller is configured to operate the one or more switches based, at least in part, on a distance between the transmitter and a receiver.

Abstract
Systems and methods for transmitting and receiving wireless power are disclosed. A transmitter may include one or more magnetic inductive coil(s) configured to transmit power, a plurality of drive loops, one or more switches connected to the plurality of drive loops, and a controller configured to connect or disconnect the drive loops using the one or more switches. A receiver may include one or more magnetic inductive coil(s) configured to receive power, a plurality of load loops, one or more switches connected to the plurality of load loops, and a controller configured to connect or disconnect the load loops using the one or more switches. The wireless power system may include inductive coils and RF antennas that are adaptively controlled and configured. A transmitter and/or a receiver may adaptively rotate, adjust orientation and/or location.
