    Abstract: A wireless power transmitter configured to transmit power to a wireless power receiver and a method for controlling the wireless power transmitted are provided. The method includes applying a detection power for detecting a change in a load impedance of the wireless power transmitter caused by a placement of the wireless power receiver, detecting the change in the load impedance of the wireless power transmitter, receiving a first signal from the wireless power receiver, determining whether a reception intensity of the first signal is greater than a threshold, and transmitting a second signal to the wireless power receiver based on detecting the change in the load impedance and determining whether the reception intensity of the first signal is greater than the threshold.

    Abstract: Methods and apparatus are provided for controlling power transmission in a power transmitter against overvoltage at a power receiver. The power transmitter receives a subscription request to subscribe to a wireless power network, from the power receiver. It is determined whether power transmission is available for the power receiver. The power receiver is informed that the power transmission is beginning, when the power transmission is available. The transmission power is increased and transmitted. It is determined whether a stop request to stop increasing voltage is received at the power transmitter from the power receiver. The increase of the transmission power is stopped when the stop request is received at the power transmitter. Charging of the power receiver is started by transmitting a start charging command from the power transmitter to the power receiver.

    Abstract: Methods and apparatuses are provided for controlling a wireless power transmitter. First power for charging a first wireless power receiver is transmitted. Demand power information of a second wireless power receiver is received. The demand power information includes a maximum power for the second wireless power receiver. A controller identifies whether the wireless power transmitter is capable of providing the maximum power. A power adjustment command is transmitted to the second wireless power receiver, if the wireless power transmitter is not capable of providing the maximum power. The power adjustment command requests to reduce a magnitude of power to be received by the second wireless power receiver to a level within a range that the wireless power transmitter is capable of supporting. Second power for charging the first wireless power receiver and the second wireless power receiver is transmitted based on at least the reduced magnitude of power.
