Abstract: Methods and apparatuses are provided for controlling power transmission in a power transmitter. Voltage information including a minimum voltage, a maximum voltage, and a first voltage, is received from each of a plurality of power receivers. Power is transmitted to the plurality of power receivers based on the voltage information. A respective report about a power reception condition is received from each of the plurality of power receivers while transmitting the power. Each respective report includes a measured voltage at a corresponding power receiver of the plurality of power receivers. A power receiver is selected from among the plurality of power receivers based on the received reports. An amount of the power is adjusted by reducing a difference between a first voltage of the selected power receiver and a measured voltage of the selected power receiver.
