Contactless power supply achieves power transmission by no mechanical contact, which is flexible, safe and reliable. The contactless characteristics are very suitable for high speed maglev train driven by long stator linear synchronous motor (LSM). The problems of vehicle power supply system for exiting electromagnetic suspension (EMS) high speed maglev system are analyzed. The contactless power supply method of maglev train at low speed and high speed is studied. At low speed of the train, the separate transformer is used to transmission power, and several kinds of separate transformer structure and compensation methods of primary coils and secondary coils are analyzed and proposed. Generators installed on the train are used to generate power by the cogging effect of the long stator LSM during the train running at high speed. The working mode of the contactless power supply system at all speed section of the maglev train is also discussed.
