Abstract:
This disclosure provides systems, methods and apparatus for decoupling multiple wireless charging transmitters. In one aspect, a device is configured to transmit wireless power to a first receiver. The device includes a first driver coil and a second driver coil. The device further includes a common reactance element connected to the first driver coil and the second driver coil. The reactance element is configured to at least partially cancel mutual inductance between the first driver coil and the second driver coil.
