Zusammenfassung:According to an embodiment of the present invention, the present invention provides a wireless power transmission device capable of reducing production costs. The wireless power transmission device comprises: an alternating current (AC) power outputting unit converting and outputting input power into AC power; and a power transmission unit including a plurality of resonators, and receiving the AC power to wirelessly transmit the power. In a first operation mode, two resonators among the plurality of resonators are connected in series, and the power is wirelessly transmitted by using the resonator to be connected in series. In a second operation mode, one among the plurality of resonators is used to wirelessly transmit the power. 본 발명의 실시예에 따르면, 무선 전력 송신 장치가 공개된다. 본 발명의 실시예에 따른 무선 전력 송신 장치는 입력 전력을 교류 전력으로 변환하여 출력하는 교류 전력 출력부, 및 복수개의 공진기들을 포함하며, 상기 교류 전력을 인가받아 전력을 무선으로 송신하는 송전부를 포함하고, 제1 동작 모드에서는 상기 복수개의 공진기들 중 2개의 공진기가 직렬로 연결되고 직렬로 연결된 공진기들을 이용하여 전력을 무선으로 송신하고, 제2 동작 모드에서는 상기 복수개의 공진기들 중 하나를 이용하여 전력을 무선으로 송신한다.
