Abstract: The present invention suggests a method to define a section where the optimum power receiving rate can be achieved in a power receiver. To do so, the present invention includes a process to define a section where the power receiving efficiency can be maximized between the minimum voltage and the maximum voltage of a power receiver. When the optimum reference voltage required by the power receiver between the minimum voltage and the maximum voltage is defined, the section between the minimum voltage and the reference voltage is determined as the optimum efficiency voltage section where the power receiving efficiency can be maximized. The reference voltage is determined by a power transmitter or the power receiver, and the power transmitter adjusts the output voltage to be transmitted to the power receiver in order to make the received voltage in the power receiver fit in the optimum efficiency voltage section. By doing so, the power transmitter is able to adjust the power adaptively considering the optimum efficiency voltage section of each power receiver even when sending power to multiple power receivers, thereby maximizing the power transmission efficiency.

Abstract: PURPOSE: A wireless power transmitter, a wireless power receiver and a control method thereof are provided to prevent supply of the charged power by excluding a cross-connected wireless power receiver. CONSTITUTION: A communication request signal for wireless power transmission is received from wireless power receivers (110-1,110-2,110-n). Whether or not the communication with a wireless power receiver is set up is determined based on the received communication request signal. When the communication with a wireless power receiver is determined to set up, a charge command signal commanding an on-state control of a load switch on a pre-set timing is transmitted to the wireless power receiver. After the charging power is approved, a load change by the wireless power receiver is detected. The detected load change timing is compared to the pre-set timing controlling the on-state command of the load switch included in the charge command signal.
