摘要： 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.

摘要： Devices and methods for distributing power are disclosed. For example, one device includes multiple assemblable elements, each assemblable element is configured to permit interlocking between one or more of the multiple assemblable elements. The multiple assemblable elements each include a portion of a coil. The portions of the coil are electrically interconnected and configured to provide wireless power to a receiving device.
