A non-contact power transmission system (200) is provided with a plurality of power transmission devices (50) capable of transmitting power to a power reception device (30) in a non-contact manner. The power transmission device is provided with a power transmission coil (51) that is provided within the movable range of the moving body (20) and that transmits power to the power receiving device of the moving body in a non-contact manner. Comprises: a main power supply line (RFP) for supplying AC power of a first voltage for power transmission to a plurality of power transmission devices; and a DC power supply unit (60) that receives the supply of AC power from the main power supply line and outputs power of a second voltage that is lower than the first voltage and is used for controlling the inside of the power transmission device. Consequently, a non-contact power transmission system in which the power supply for controlling the power transmission device is simplified can be realized.
一种非接触送电系统(200),包括能够以非接触的方式向受电装置(30)送电的多个送电装置(50)。该送电装置包括送电线圈(51),上述送电线圈设置在移动体(20)的可动范围内,并且以非接触的方式向移动体的受电装置送电。包括:主电源线(RFP),上述主电源线向多个送电装置供给用于送电的第一电压的交流电力;以及直流电源部(60),上述直流电源部从主电源线接收交流电力的供给,并且输出比第一电压低的电压的、用于送电装置内的控制的第二电压的电力。由此,能够实现简化了送电装置的控制用的电源的非接触送电系统。
