Control method of charging and charging device for magnetic levitation vehicle

摘要

PURPOSE:To realize accurate noncontact stoppage of a vehicle and noncontact power supply to a vehicle-borne battery by a system wherein a primary coil and an AC power supply are disposed on the ground side whereas a secondary coil and a charging circuit are disposed on the vehicle side. CONSTITUTION:A primary coil 40 connected through a switch 39 with an AC power supply 38 is mounted on a travel path body frame. On the other hand, a vehicle 3 is provided with a secondary coil 41 oppositely to the primary coil 40. Upon receiving a vehicle arrival command from a position sensor, a switch driver 37 closes the switch 39 to turn ON the AC power supply 38 for the primary coil 40. Consequently, magnetomotive force is induced in the primary coil 40 and the secondary coil 40 is attracted thereby retaining the vehicle at a predetermined stop position. The secondary coil 41 is excited under that state and a current is induced therein. According to the constitution, required charging power is fed, in noncontact, through the primary and secondary coils.
