POWER TRANSMITTING UNIT AND POWER RECEIVING UNIT WITH CONTROL DATA COMMUNICATION AND METHODS FOR USE THEREWITH

Aspects of the subject disclosure may include, for example, a wireless power receiver configured to receive a wireless power signal from a power transmitting unit. A wireless radio unit is configured to communicate with the power transmitting unit. A controllable rectifier circuit is configured to rectify the wireless power signal. The controllable rectifier circuit can include a rectifier configured to generate a rectified voltage from the wireless power signal, based on switch control signals. A rectifier control circuit is configured to generate the switch control signals and to generate first control data that indicates a first rectifier duty cycle of the switch control signals. The wireless radio unit sends the first control data to the power transmitting unit. Other embodiments are disclosed.
