Abstract: The triggered vacuum switch (TVS) is a kind of controllable good, high-power switching device applied in the pulse power technology. The application of TVS was much wider in power system, as well as in pulsed power supply. Introduction was made to the basic structure, classification and merits of TVS. This paper analyzed the research status about the closure phenomenon, initial plasma and back arc current, which provides references for the research and development of following TVS.
Key words: trigger vacuum switch; pulse power techniques; vacuum medium; arc plasma
