Short-Pulse Switches for Airborne High-Power Supplies
Abstract
Switching systems for use with pulsed inductive energy storage systems were investigated with the goal of designing for a peak current interrupt capability of 20,000 A at a repetition rate of 5 pps with a voltage following interruption of 100 kV. A charge time of 190 msec or more was desired with switch losses limited to 5,000 j/pulse for a total pulse train length of 300 pulses. Both linearly actuated and rotary devices were considered with means for incorporating an applied magnetic field and cryogenic cooling in the switch design. A design is given for a prototype linearly actuated switch for evaluation of the field and cooling effects and for a rotary switch based on high performance filamentary brushes designed for operation at 3,000 A/sq in. Test results were obtained in the program with filamentary brushes operating at this overall current density. Current densities in the filaments were as high as 9,000 A/sq in.
