Provided is a non-contact power supply system (1) configured to perform non-contact power transmission by magnetic field resonance coupling between a ground-side device (2) and a moving object (3), comprising: a transmission-side resonance circuit (43) configured to transmit power; a power reception-side resonance circuit (51) configured to receive power from the transmission-side resonance circuit (43); an alternating current magnetic field generation circuit (6) configured to generate an alternating current magnetic field for detecting the relative positional relationship between the transmission-side resonance circuit (43) and the power reception-side resonance circuit (51); and a magnetic field detector (7) configured to detect alternating magnetic fields, wherein the frequency of the alternating magnetic field for position detection is different from the resonance frequencies of the transmission-side resonance circuit (43) and the power reception-side resonance circuit (51). Accordingly, the present invention can detect the relative positional relationship between the transmission-side resonance circuit and the reception-side resonance circuit with good accuracy.

    전력을 송신하도록 구성되어 있는 송전측 공진 회로 (43) 와, 상기 송전측 공진 회로 (43) 로부터 전력을 수신하도록 구성되어 있는 수전측 공진 회로 (51) 와, 상기 송전측 공진 회로 (43) 와 수전측 공진 회로 (51) 의 상대적인 위치 관계를 검지하기 위한 교류 자계를 발생시키도록 구성되어 있는 교류 자계 발생 회로 (6) 와, 교류 자계를 검출하도록 구성되어 있는 자계 검출기 (7) 를 구비하고 있고, 지상측 장치 (2) 와 이동체 (3) 사이에서 자계 공진 결합에 의한 비접촉 전력 전송을 실시하도록 구성된 비접촉 급전 시스템 (1) 이 제공된다. 위치 검지용의 교류 자계의 주파수는, 송전측 공진 회로 (43) 및 수전측 공진 회로 (51) 의 공진 주파수와 상이하다.
