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.
