Abstract

The invention relates to a levitation controller of a magnetic-levitation train. The levitation controller is used for controlling an electromagnet of the magnetic-levitation train, and comprises three control units, wherein the first main control unit and the second main control unit have the same structures; each of the first main control unit and the second main control unit comprises a main control circuit (C1 / C2), a main gating power switch (K1 / K2), a main power conversion circuit (P1 / P2) and a main auxiliary power supply (DC1 / DC2); a redundancy control unit comprises a redundancy control circuit (C3), two redundancy gating power switches (K3 and K4), a redundancy power conversion circuit (P3) and a redundancy auxiliary power supply (DC3); and the redundancy control circuit (C3) communicates with the two main control circuits (C1 and C2) to form the redundancy control. Compared with the prior art, the levitation controller has the advantages that through the redundancy structure design, the redundancy control circuit is enabled to communicate with the two main control circuits; the redundancy problem of a levitation control system of a medium-and-low-speed magnetic-levitation train is solved; when the levitation controller partially fails, the magnetic-levitation train can normally work; and the availability of the magnetic-levitation train is improved.

Description

technical field [0001] The invention relates to a maglev control device, in particular to a levitation controller for a maglev train, which belongs to the levitation controller technology using electromagnetic levitation or permanent magnet electromagnetic hybrid levitation. Background technique [0002] The maglev train is a new type of rail transportation with outstanding features such as low operating noise, strong climbing ability, small turning radius, high safety and reliability, low operation and maintenance costs, and low construction cost. It uses electromagnetic suction to suspend the car body above the track, and maintains a non-contact state between the train and the track, which overcomes the contact wear between the two and reduces the running resistance. The suspension controller is the actuator to realize the suspension of the vehicle. It changes the size of the internal current of the suspension electromagnet according to the air gap between the suspension e...
