Abstract: Methods and apparatuses are provided for method is provided for controlling power transmission in a power transmitter. Voltage information required by a plurality of power receivers is received from the plurality of power receivers. The voltage information includes a minimum voltage, a reference voltage that is greater than the minimum voltage, and a demanded voltage. Power is transmitted to the plurality of power receivers. A report about a power reception condition while transmitting the power is received from the plurality of power receivers. The report includes a measured voltage at the plurality of power receivers. One of the plurality of power receivers is selected. An amount of the power is adjusted by minimizing a difference between the demanded voltage and the measured voltage of the selected power receiver.

Abstract: Methods and apparatus are provided for controlling power transmission. A minimum voltage and a maximum voltage receivable at the at least one power receiver, a reference voltage used to divide a range between the minimum voltage and the maximum voltage, and a demanded voltage required by the at least one power receiver, are received from at least one power receiver. A report about a power reception condition is received from the at least one power receiver. The report includes a measured voltage at the at least one power receiver during power transmission from the power transmitter. It is determined whether the measured voltage is between the minimum voltage and the reference voltage. Power is adjusted and supplied when the measured voltage is not between the minimum voltage and the reference voltage.
