摘要： A voltage control method. A train traveling speed can be acquired; a target transformation ratio corresponding to the train traveling speed is determined according to correspondences between train traveling speeds and transformation ratios, the transformation ratio being a ratio of an input voltage to an output voltage; an input voltage is then transformed according to the target transformation ratio to obtain an output voltage, the output voltage being used for driving a train to travel. The correspondences between train traveling speeds and transformation ratios are obtained according to correspondences between train traveling speeds and train traction forces at different transformation ratios. By means of the method, the most suitable transformation ratio can be provided according to a traveling speed of a maglev train, thereby increasing the traction force of the maglev train and improving running efficiency.

摘要： An electromagnetically-propelled vehicle includes a charged-particle accelerator and a magnetic-field generator. Charged particles are accelerated to a velocity v and are directed through the magnetic field B generated by the magnetic-field generator. The interaction between the accelerated charged particles and the magnetic field generates a force between the particles and the magnetic-field generator that may be used to propel or levitate the vehicle.

摘要： A hybrid electrodynamic levitation system that utilizes both superconducting and conductive tracks. The hybrid system reduces the overall drag induced upon the system and reduces the amount of power required to achieve operating speeds, while resolving the issue of requiring velocity relative to the track for levitation. The total initial and operating costs of the hybrid system can be lower than utilizing a superconductive or conductive track alone, while still enabling a fail-safe levitation system for high speed transportation.
