Abstract


Pulsed power technology is one of the basic techniques in the high technology research fields, and it is widely applied to the fields of national defense, scientific research and high technology. Moreover, it is used in the civilian industrial departments more and more. The key technique of the pulsed power is to research the high density energy storage devices and the high power pulse storage system. It is required that the pulse discharge wave would be controlled to fulfill with the load requirement. At the same time, the repetition of the pulse discharge is required. The structure of the system would be simple. Superconducting Magnet Energy Storage (SMES) with the advantage of high efficiency, high energy density, fast energy discharge and easy control, can be used to achieve lightweight, miniaturization and practicality in pulse power device.In the paper, to study key technology of the SMES pulsed discharge, the needs of different wave high-power pulse output come true, to provide the current pulse power source for specific device.Firstly, the characteristic of the superconducting magnet is analyzed, involving in the magnet stability and quench protection. It is provided a criterion for the superconducting magnet design. Secondly, the characteristic of the common opening switch is analyzed relatively. The pulse forming circuit of the SMES is analyzed in theory and computed with simulation. It is provided a theoretic basis for main circuit design of the SMES system. Finally, the common testing schemes of pulse current are compared and analyzed. Based on the pulse discharge characteristic of the SMES, the pulse signal testing system is designed.According to these accounts, for the experimental SMES, Based on IGBT the main circuit of the pulse discharge system is designed. Based on the virtual instrument, the pulse signal testing system is designed. The drive circuit of the opening switch is set up. The on-off states of the switch are controlled by the time sequence of CPLD. Using the Lab VIEW in computer, the circuit signal is collected, displayed and stored. The function of the system is validated by the experiment, and the right pulse output of the load is obtained.The theoretic analysis and experiment results indicate that the electricity pulse signal can be obtained by the superconductivity technology. The pulse wave can be formed by the time sequence switch.
