Abstract
A wireless power enabled apparatus may comprise a wireless power receiver that includes a receive coil configured to generate an AC signal responsive an electromagnetic field, a rectifier including a plurality of switches configured to receive the AC signal and generate an output power signal, and control logic configured to control the plurality of switches to cause the rectifier to modulate the output power signal. The control logic may be configured to control the plurality of switches within the rectifier to have an overlap delay that modulates at least one parameter of the wireless power receiver. A method of operating a receiver side of a wireless power transfer system comprises generating an output power signal including a rectified voltage and a rectified current responsive to receiving a wireless power signal, and controlling a rectifier according to at least one mode including a power modulation mode modulating the output power signal.
