Design And Realization Of The Power Supply System In HTS Maglev Launch Device

High-temperature superconducting (HTS) maglev launch technology is a ne-w launch technology. The HTS maglev technology is applied in the military launch area, to provide a larger thrust to the carrier which could make the launched body take off with a higher velocity.As a result, the carrier could take more payl-oad into preconcerted orbit.HTS maglev launch technology has a lot of advanta-ges,such as low-cost,high- performance,and so on.Therefore it becomes a optional advanced technology for the next generation launch system.To supply a drive force,linear motor is applied to HTS maglev launch technology.Launching body is launched away when it is accelerated to the most high speed.In fact, HTS maglev launch device is a special electric transmission.and power supply system as its energy assurance. In order to supply power which fulfil the quality requirements, reduce the power faults,and ensure the safe and continuous running of each motor,a electricity supply system has to be designed with high reliability, high availability and stronge anti-jamming ability.To satisfy the needs above,meanwhile,improve operating efficiency of HTS maglev electropult's drive system and reduce the load of energy system,a set of power supply control system based on the single-chip is designed in this paper, which has the following functions:1. Realize the subsection power supply, in other words, only supply power to the motors under the running carrier,and disconnect others.With the changing displacement of the running carrier, the electric power would be supplied to the different motors.2. Monitor the operation speed of electropult's launcher carrier,as the important reference data of further studies on HTS maglev launch technology.
