Wireless power transmitter tuning
First Claim
1. A device configured to provide wireless power, comprising:
- a signal driver configured to provide power along a power path;
a first tuning circuit along the power path, configured to tune reactance at the signal driver; and
a second tuning circuit along the power path, configured to tune reactance at the signal driver and to at least partly cancel a harmonic generated at the first tuning circuit.

Abstract
This disclosure provides systems, methods and apparatus for tuning a wireless power transmitter. In one aspect a device configured to wirelessly provide power to a load is provided. The device includes a signal driver configured to provide power along a power path. The device further includes a first tuning circuit along the power path, configured to tune reactance at the signal driver, introducing undesired harmonic content. The device further includes a second tuning circuit along the power path, configured to tune reactance at the signal driver and to generate complementary harmonic content, at least partly canceling the harmonic generated at the first tuning circuit.

10. A method of providing wireless power, comprising:
-
providing, at a signal driver, power along a power path; generating a harmonic at a first tuning circuit along the power path; and generating another harmonic at a second tuning circuit along the power path, the another harmonic at least partly canceling the harmonic generated at the first tuning circuit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An apparatus for providing wireless power, comprising:
-
means for providing power along a power path; first means for tuning the power path and generating a harmonic; and second means for tuning the power path and generating another harmonic, the another harmonic at least partly canceling the harmonic generated by the first means for tuning. - View Dependent Claims (20, 21)
