Abstract: Methods and apparatuses are provided for controlling power transmission in a power transmitter. A first message including a first voltage and a second voltage that is greater than the first voltage, is received from at least one power receiver. Power is transmitted to the at least one power receiver. A second message including a third voltage measured at the at least one power receiver during power transmission from the power transmitter, is received from the at least one power receiver. An amount of the power is adjusted based on whether the third voltage is between the first voltage and the second voltage. The first voltage is a minimum voltage for the at least one power receiver.
