Zusammenfassung:	According to a technical aspect of the present invention, a wireless power transmitter comprises: a switch unit for receiving direct current power, and switching to generate alternating current; a control unit for controlling switching of a plurality of switches included in the switch unit; and a resonator including a plurality of resonant circuits operating by receiving the alternating current. The plurality of resonant circuits can be connected in parallel with each other by using a ground terminal as a neutral point. The wireless power transmitter reduces inductance of each coil of the plurality of resonant circuits to satisfy price competitiveness and a need of miniaturization. 본 발명의 일 기술적 측면에 따른 무선 전력 송신 장치는, 직류 전원을 입력받고 스위칭 동작하여 교류 전류를 생성하는 스위치부, 상기 스위치부에 포함된 복수의 스위치들의 스위칭을 제어하는 제어부 및 상기 교류 전류를 입력받아 동작하는 복수의 공진 회로를 포함하는 공진기를 포함할 수 있다. 상기 복수의 공진 회로는 접지단을 중성점으로 하여 서로 병렬 연결될 수 있다.
