Abstract
Systems and methods for wireless power transfer systems are described. A controller of a device can communicate with a power device by a first modulation mode. The controller can detect a failure condition between the controller and the power device. The controller can, in response to the detection of the failure condition, communicate with the power device by a second modulation mode. The first modulation mode can include capacitive modulation and the second modulation mode can include resistive modulation.
