Basal Research On HTS Magnetic Energy Storage Pulsed Current Generator

Pulsed power technology is attached great importance to the application for the scientific research, future launch vehicles and new concept weapons. The basic principle of this technology is slow accumulation of electrical energy and its compress, reshape, transmission in short time to obtain high power output. The superconducting technology applied in pulsed power apparatuses such as energy storage magnet, pulsed transformer, switch, inductive device and coils would be very promising. In this dissertation, based on an superconducting magnetic energy storage (SMES) pulsed power output circuit, relating problems were investigated for the purpose of realizing superconducting pulsed power application. Main works in this dissertation are as follows:(1) Based on theoretical analysis, a simulation model for this pulsed power circuit was built;(2) Investigatation of the mutual inductance problem faced in multi-module time-delay output, an improved control strategy was proposed;(3) Quantitative analysis of effect the pulse transformer have on energy transmission, energy consumption on protection resister and current remain on SMES were pointed out;(4) Feasibility of this device was proved through experimental research, based on which an 125Hz pulsed current generator was designed to drive an electromagnetic launcher;(5) Proposed self-coupling pulse output strategy to utilize the HTS's recovery property under pulsed current, and to decrease the number of switch in the circuit.
