Experimental investigations on triggering characteristic of TVS under DC and AC load

Abstract

Triggered vacuum switches (TVSs) have fast growing applications in the field of power system and pulse power. The relation between triggering parameters of triggering system, such as triggering voltage and triggering power, between the triggering time delay and its scatter of TVS had been obtained through series of experiments. The result can be adopted as the steering for high-power controller design and application of TVS. A steepened high-voltage triggering pulse is introduced in the main high-voltage generating circuit. As a result, the triggering time delay and its scatter can be decreased remarkably. Synchronous switch technology is imported to control the triggering phase at the crest of applied voltage on TVS. The Triggering characteristic of TVS under alternating current (AC) and direct current (DC) load has been investigated emphatically. Given the identical triggering parameter of triggering system, DC condition is prior to AC on the triggering probability and stability markedly. Such conclusion can be drawn, for AC condition, TVS would require much for the triggering system.
