An Investigation of Performance Characteristics of High-Voltage Trigatron

Abstract:

A new-style high-voltage switch named trigatron with great advantage, such as simple structure and applying circuits, wide operational temperature and voltage range, short delay time, long operational life is introduced in this paper. Firstly the four operational modes which trigatrons are suitable for pulse power devices are presented. Then through experimental study and theoretical analysis, the effect factors of turn-on time of trigatrons are summed up, including anode voltage, triggering voltage and triggering-wire’s length, finally giving a conclusion that the higher anode voltage and triggering pulse voltage are, the more steady and shorter turn-on time is.
