The invention relates to the technical field of power supply, and discloses a non-contact power supply system and a rail transit train. The system comprises ground power supply coils, a vehicle-mounted receiving coil, a voltage-stabilizing chopper and an external power supply, the ground power supply coils are evenly arranged between tracks on the two sides in the track direction, the vehicle-mounted coil is arranged at the bottom of a train, the voltage-stabilizing chopper is arranged on the train and connected with the vehicle-mounted coil, and the external power supply supplies power to the ground power supply coils. The vehicle-mounted receiving coil receives electric energy of the ground power supply coil through electromagnetic induction and then transmits the electric energy to the voltage stabilization chopper, and the voltage stabilization chopper carries out chopping on the received electric energy and then outputs the electric energy to a load on a train. Therefore, electric energy can be transmitted to the vehicle from the ground when the vehicle is in a static state, and more stable electric energy supply can be realized along with cutting of the power supply coil by the receiving coil when the vehicle runs; in the vehicle running process, the speed, direction and position can be sensed by utilizing the relation between the induction voltage and the phase between the receiving coil and the power supply coil, and vehicle speed measurement and positioning are completed.

    本发明涉及供电技术领域,公开了一种非接触供电系统及轨道交通列车。该系统包括地面供电线圈、车载接收线圈、稳压斩波器和外部电源,地面供电线圈沿轨道方向均匀设置在两侧轨道之间,车载线圈设置在列车底部,稳压斩波器设置在列车上且与车载线圈连接,外部电源为地面供电线圈供电,车载接收线圈通过电磁感应接收到地面供电线圈的电能后传输至稳压斩波器,稳压斩波器对接收的电能斩波后输出至列车上的负载。由此,可实现车辆静止状态下电能从地面传递到车辆,在车辆运行时,随着接收线圈切割供电线圈,可实现更稳定的电能供给;在车辆运行过程中利用接收线圈和供电线圈间感应电压和相位的关系,可实现速度、方向和位置的感知,完成车辆测速定位。
