Title:
FOUR-RAIL POWER SUPPLY CONTROL SYSTEM FOR SHORT-STATOR MAGNETIC LEVITATION TRAIN
Document Type and Number:
WIPO Patent Application WO/2020/143190
Kind Code:
A1
Abstract:
A four-rail power supply control system for a short-stator magnetic levitation train. A first power supply rail (1a), a second power supply rail (1b), and a third power supply rail (1c) of the system constitute a three-phase alternating-current power supply loop, wherein the third power supply rail (1c) is grounded, the third power supply rail (1c) and a fourth power supply rail (1d) constitute a direct-current power supply loop and are laid along two sides of a magnetic levitation line; an alternating-current direct-current alternating-current frequency-conversion voltage-transformation apparatus (3) supplies power to a three-phase driving winding (6) of the magnetic levitation train by means of the three-phase alternating-current power supply loop and a vehicle-mounted current collector (2); and the direct-current power supply loop is supplied with power by means of a rectifying apparatus (4) of the ground, and then power is supplied to a train auxiliary electrical device (7) via the vehicle-mounted current collector (2).
