【Abstract】 Superconductor exhibits superconducting properties below a certain critical temperature (Tc) , critical magnetic field (Bc) , and critical current (Ic) , the current flows in the superconductor without loss, the energy can be stored in high density. If any of these parameters exceed the critical value, the material is no longer superconducting but goes into a non-superconducting (resistive) state. It is this property of the material that will be exploited to implement an opening switch. Applying superconducting inductive arid switch, this paper researches a kind of pulsed power technology, according to the characteristics of superconducting inductive storage systems and superconducting switch, the ideal structures of superconducting magnet and switch are presented, the pulsed forming network is designed , and some important questions are put forward also. Using Matlab simulation, the pulsed power is acquired under resistance load.更多还原
