WIRELESS POWER TRANSMISSION SYSTEM AND METHOD FOR INCREASING COUPLING EFFICIENCY BY ADJUSTING RESONANT FREQUENCY |
摘要 |
A wireless power transmission system and a method for increasing a coupling efficiency by adjusting a resonant frequency are provided. A device of the wireless power transmission system includes a resonator configured to transmit a wireless power, and a communication unit configured to receive information from another device. The device further includes a controller configured to determine a power transmission efficiency based on the information, and adjust a resonant frequency of the device, a resonant frequency of a relay device, and a resonant frequency of the other device, if the power transmission efficiency is less than or equal to a predetermined reference efficiency.
