Abstract
A power transmitter is provided herein. The power transmitter executes in-band communication with a power receiver. The power transmitter receives a reported voltage from the power receiver and dynamically determines a coupling between the power transmitter and the power receiver from the reported voltage. The power transmitter also dynamically determines an operating frequency for power transmission between the power transmitter and the power receiver.
Claims20
A power transmitter executing in-band communication with a power receiver, the power transmitter configured to:
- receive a reported voltage from the power receiver;
- dynamically determine a coupling between the power transmitter and the power receiver from the reported voltage;
- and
- dynamically determine an operating frequency for power transmission between the power transmitter and the power receiver.
A power receiver executing in-band communication with a power transmitter, the power receiver configured to:
- receive a ping that causes a local voltage in the power receiver;
- report the local voltage as a reported voltage to the power transmitter to cause a dynamic determination of a coupling between the power transmitter and the power receiver from the reported voltage and a dynamic determination of an operating frequency for power transmission between the power transmitter and the power receiver.
