To realize a non-contact power transmission system in which a power source for controlling a power transmission device is simplified.SOLUTION: A non-contact power transmission system 200 includes a plurality of power transmission devices 50 that can transmit power to a power reception device 30 in a non-contact manner. Each of the power transmission devices is installed within a movable range of a mobile body 20, and includes a power transmission coil 51 that transmits power to a power reception device of the mobile body in a non-contact manner. Each of the power transmission devices includes a main power source line RFP for supplying AC power of a first voltage that is for use in power transmission, and a DC power source unit 60 that receives supply of the AC power from the main power source line, and outputs power of a second voltage that is lower than the first voltage and is for use in internal control in the power transmission device.SELECTED DRAWING: Figure 1

    【課題】送電装置の制御用の電源を簡素化した非接触送電システムを実現する。【解決手段】非接触送電システム200は、受電装置30に電力を非接触で送電できる複数の送電装置50を備える。この送電装置は、移動体20の可動範囲に設けられ、移動体の受電装置に非接触で送電する送電コイル51を備える。複数の送電装置に、送電に用いる第1電圧の交流電力を供給する主電源ラインRFPと、主電源ラインから交流電力の供給を受け、第1電圧より低い電圧であって、送電装置内の制御に用いられる第2電圧の電力を出力する直流電源部60とを備える。【選択図】図1
