    Abstract: 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.

    Abstract: A transport system including at least one guideway, at least one levitation generator, at least one lifting member, at least one drive generator, and at least one drive member is presented. The at least one guideway, at least one levitation generator, at least one lifting member, at least one drive generator, and at least one drive member can each be implemented with other systems. The at least one drive generator is configured to: generate a driving magnetic flux; move with a corresponding at least one drive member; and be driven relative to the at least one drive member by the driving magnetic flux. The at least one levitation generator can be configured to: generate a levitating magnetic flux; move within a corresponding at least one lifting member; and elevate above a rest position relative to the at least one lifting member in response to the levitating magnetic flux.

    Abstract: 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.

    Abstract: The invention provides in some aspects a transport system comprising a guideway with a plurality of propulsion coils disposed along a region in which one or more vehicles are to be propelled. One or more vehicles are disposed on the guideway, each including a magnetic flux source. The guideway has one or more running surfaces that support the vehicles and along which they roll or slide. Each vehicle can have a septum portion of narrowed cross-section that is coupled to one or more body portions of the vehicle. The guideway includes a diverge region that has a flipper and an extension of the running surface at a vertex of the diverge. The flipper initiates switching of vehicle direction at a diverge by exerting a laterally directed force thereon. The extension continues switching of vehicle direction at the diverge by contacting the septum. Still other aspects of the invention provide a transport system, e.g., as described above, that includes a merge region with a flipper and a broadened region of the running surface. The flipper applies a lateral force to the vehicle to alter an angle thereof as the vehicle enters the merge region, and the broadened region continues the merge by contacting the septum of the vehicle, thereby, providing further guidance or channeling for the merge. The flipper, which can be equipped for full or partial deployment, is partially deployed in order to effect alteration of the vehicle angle as the vehicle enters the merge.

    Abstract: The invention provides in some aspects a transport system comprising a guideway having a plurality of regions in which one or more vehicles are propelled, where each such vehicle includes a magnet. Disposed along each region are a plurality of propulsion coils, each comprising one or more turns that are disposed about a common axis, such that the respective common axes of the plurality of coils in that region are (i) substantially aligned with one another, and (ii) orthogonal to a direction in which the vehicles are to be propelled in that region. The plurality of coils of at least one such region are disposed on opposing sides of the magnets of vehicles being propelled along that region so as to exert a propulsive force of substance on those magnets. In at least one other region, the plurality of coils disposed on only a single side of the magnets of vehicles being propelled in that region exert a propulsive force of substance thereon—regardless of whether the plurality of coils in that region are disposed on a single or multiple (e.g., opposing sides) of those magnets.
