Performance of pulsed power generator using high-voltage static induction thyristor

In a present pulsed power generator system using semiconductor snitches, sa turable magnetic switches are usually connected in series to compress the o utput pulse because the current rise-time of semiconductor switches are gen erally not short enough, However, the magnetic switches are heavy and they reduce the energy transfer efficiency, So we propose a pulsed power generat or system using a 5500-V static induction thyristor (SI-Thy), a Blumlein fi ne for pulse formation, and a step-up pulse transformer The fundamental cha racteristics of the generator are evaluated, From experiments using only on e SI-Thy, turn-on time of several tens of nanoseconds and the maximum rise rate of the output voltage of 115-kV/mus are obtained. It is confirmed that an SI-Thy will have sufficient performance as a main switch of the pulsed power generator for the flue gas treatment and decomposition of hazardous g ases when several SI-Thys are connected in series.
