Research on Superconducting Energy Storage Inductors for Reconnected Electromagnetic Propulsion Power Supply
In order to verify the feasibility of using high-temperature superconducting energy storage inductors as reconnected electromagnetic propulsion pulse power supplies,Ansoft Maxwell 3D is used to establish a transient simulation model of reconnected electromagnetic thrusters.The design of pulse power supply combines multiple module energy storage inductors in series charging and parallel discharging modes,and conversion capacitors are used in the circuit to limit the high voltage during the operation of the circuit breaker.The inductor and capacitance parameters have a certain impact on the optimal triggering discharge position,that is,on the rise time of the driving coil current pulse.Because the speed at which the magnetic field is established by the driving coil determines the size of the eddy current induced by the projectile,the driving force received by the projectile is related to the size of the driving coil magnetic field and the speed at which the magnetic field is established.In the parameter design of multi-stage propulsion systems,in addition to reducing the triggering discharge position,it is also necessary to appropriately reduce the inductance of the driving coil and the parameters of the conversion capacitor.
