Power supply system used for suspension control system

Abstract

The invention discloses a power supply system used for a suspension control system. The system comprises a suspension power supply and a control power supply, wherein the two poles of the suspension power supply are connected with a suspension chopper circuit so as to be used for supplying power for the suspension chopper circuit; and the two poles of the control power supply are respectively with the two poles of a plurality of low-voltage direct-current power supplies so as to be used for supplying power for the low-voltage direct current power supplies. According to the power supply system, the condition that the suspension power supply can be impacted due to the work of the suspension chopper circuit when a train is in suspension can be avoided, so that the low-voltage direct current power supplies can be prevented from being interfered, the low-voltage direct current power supplies can output current and voltage stably, the normal work of a suspension controller, various suspension parameter measuring sensors, a driver of a chopper power tube, and the like can be ensured, further, the normal work of the suspension control system is ensured, and the safety of the suspension control system is improved.

Description

technical field [0001] The invention relates to the technical field of circuit structures, in particular to a power supply system for a suspension control system. Background technique [0002] A maglev train is a train propelled by magnetic levitation force. It has a suspension control system that enables the train to run off the track. The suspension control system is composed of a suspension controller, a suspension chopper, various sensors, etc. The sensor can measure the suspension gap, the acceleration of the electromagnet movement and the current signal flowing through the electromagnet and input it to the suspension controller. The sensor signal calculates the appropriate control command, and the suspension chopper is the actuator of the suspension controller. It changes the current of the suspension electromagnet by changing the effective voltage applied to both ends of the suspension electromagnet according to the input control command, thereby adjusting The attrac...
