摘要： The present invention relates to a method for identifying a wireless power receiver and devices therefor. According to an embodiment of the present invention, a wireless power transmission device for transmitting power wirelessly to a wireless power reception device may comprise: a power conversion unit for converting, to a specific direct current power, a direct current power received from a power supply unit; and a feedback circuit for controlling an output voltage of the power conversion unit so that intensity of current that is input to the power conversion unit is maintained constant. Therefore, the present invention is advantageous in that the present invention enables transmission of appropriate power to a wireless power receiver even in a situation where a coupling coefficient between transmission/reception coils changes abruptly.

摘要： An apparatus and method for wirelessly transmitting electromagnetic energy are provided. The apparatus includes a power source, a transmission unit, and a measurement unit. The power source supplies a power according to a certain frequency. The transmission unit receives the power to wirelessly transmit the received power through self resonance. The measurement unit measures a phase difference between a voltage and current of the transmission unit. The certain frequency is controlled according to the phase difference. Accordingly, the apparatus and method control only the frequency of the power supply when a resonance frequency is changed by the change of an ambient environment, thus enhancing energy transmission efficiency.
