Experimental investigations on the triggering characteristic of triggered vacuum switch under DC and AC load

Triggered vacuum switches (TVS), have found fast growing applications in the field of power system and pulse power. The relation between triggering parameter of triggering system, such as triggering voltage and triggering power, between the trigger time delay and it s scatter of triggered vacuum switch (TVS) had been obtained through series of experiment. The result can be adopted as the steering for high-powered controller design and application of TVS. A steepened high-voltage trigger pulse is introduced in the main high-voltage generating circuit. As a result the trigger time delay and it s 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 AC and DC load has been investigated emphatically. Given the identical triggering parameter of triggering system, the DC condition is prior to AC on the triggering probability and stability markedly. Such the conclusion can be drawn, for AC condition TVS would require much for the triggering system.
