    摘要： A wireless power transmission device and method are provided. An amount of power transmitted wirelessly by the wireless power transmission device may be controlled based on information to be transmitted by the wireless power transmission device, such that the information may be transmitted without using any additional device for information transmission. Additionally, an internal impedance of a terminal may be controlled based on information to be transmitted by the terminal, and a reflected wave of a transmission signal transmitted by the wireless power transmission device may be then controlled, such that the information may be transmitted without using any additional device for information transmission. Therefore, no further device may be desired, and thus a power consumption amount may be reduced, and there may be no need to match a communication part for information exchange with a transmission part for wireless power transmission.

    摘要： A load impedance decision device, a wireless power transmission device, and a wireless power transmission method are provided. At least one of a distance and an angle between two resonators may be measured. A load impedance may be determined based on at least one of the measured distance and the measured angle. When the distance between the two resonators changes, a high power transfer efficiency may be maintained without using a separate matching circuit. Where the load impedance is determined, a test power may be transmitted. Depending on a power transfer efficiency of the test power, the load impedance may be controlled and power may be wirelessly transmitted from the source resonator to the target resonator.
