Enlargement of capacity and functionality of the pulse power generator are hoped due to its use expansion to the industrial fields. We have developed the high repetitive static impulse generator using technologies of a successive trigger operation and resonant/parallel charging method and Thyristor switches. In this paper, we propose reliable and high functional trigger circuit system with a provision for miss-operation of trigger circuit due to the surge voltage, wide range operation voltage and high speed operation. And using five, seven, ten, and seventeen stage IG, we demonstrated its feasibility. In addition, replacing to IGBT with Thyristor, we improved its properties of rice time and voltage amplification ratio.
