11. A method of transmitting wireless power to a first receiver, comprising:
-
determining, at a transmitter comprising a first driver coil and a second driver coil, a position of the first receiver; transmitting wireless power to the first receiver; and adjusting a characteristic of the first driver coil and/or a second driver coil, based on the determined position of the first receiver, wherein the transmitter further comprises a common reactance element connected to the first driver coil and the second driver coil, configured to at least partially cancel mutual inductance between the first driver coil and the second driver coil. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
