Abstract
Power transmission associated with wireless charging of a battery of an electronic device or powering of the electronic device comprises determining a power loss associated with transmitting a power signal having a transmitted power from the wireless power transmitter to a wireless power receiver. A closed loop power loss control based on the power loss is performed which comprises outputting a target transmit power to meet a power loss limit. The power signal having the target transmit power is wirelessly transmitted to the wireless power receiver to charge the battery of the electronic device or power the electronic device and balance charging performance and safety.
