Abstract: Aspects of the subject disclosure may include, for example, a power receiving unit that includes a first wireless power receiver configured to receive a first wireless power signal in accordance with a first wireless power standard and a second wireless power receiver configured to receive a second wireless power signal in accordance with a second wireless power standard. A controllable rectifier circuit is configured to rectify either the first wireless power signal or the second wireless power signal. The controllable rectifier circuit includes a rectifier circuit configured to generate a rectified voltage from the wireless power signal, based on switch control signals. A rectifier control circuit is configured to determine whether the first wireless power signal or the second wireless power signal is received and to generate the switch control signals, based on whether the first wireless power signal or the second wireless power signal is received.
