Inductive Store/Transformer Driven Diode System
Abstract
The recent demonstrations of reliable fuse/opening switch operation at high currents and short time scales suggest that inductive store/opening switch (IS/OS) circuits with their inherent advantages of small size and light weight may be appropriate for a wide variety of applications. Among these is the possibility of developing a power system for high current, high voltage diodes. While conventional IS/OS circuits can be employed, the MV voltages required make the fuse excessively long, mechanically cumbersome, and very inductive. An alternative is the use of a circuit in which the diode is driven from the secondary of a step-up transformer and the fuse interrupts the primary circuit. This paper describes the circuit analysis, .design, fabrication and test of a transformer driven diode system whose objectives are 10 KA currents and 0.5 to 1.0 MV. Results of system tests in which a 60 KJ source is used to charge an 800 nH primary inductance through an electrically exploded fuse will be presented. The transformer employs a 1:6 turns ratio, and the fuse interrupts 100-200 KA currents at 200 KV to apply a voltage pulse to the load which rises in 100 ns.
