Abstract

Abstract

Pseudo-spark switch, with the advantages of large pulse current, wide operating voltage, long life expectancy and high reliability, is one of the key devices in the field of pulse power technology. To meet the miniaturized development requirement in the complete machine, the miniature pseudo-spark switch has been developed. The electron source is injected by introducing the trigger needle into the hollow cathode innovatively in order to achieve glow discharge. Through this physical design the volume of the pseudo-spark switch has been decreased as well as the design rationality has been verified by producing and testing the pseudo-spark switch. The test results indicate that the anode working voltage is ranged from 500 V to 10 kV and the anode pulse current is 40 kA. Under the condition that the anode pulse current is 36 kA, no sign of performance decline has been found after more than 20000 times of work. The sample has passed the reliability test of high temperature, low temperature, temperature cycle and vibration.
