Abstract
A wireless power transmission apparatus includes: an alternating current (AC) power output to convert input power into AC power and output the AC power; and a power transmitter including a plurality of resonators. The power transmitter receives the AC power and wirelessly transmits the AC power in a first operating mode in which two of the resonators are connected in series and the two resonators transmit the AC power, and in a second operating mode in which one of the resonators transmits the AC power.
