A study of switching properties of SI thyristor using high current gate circuit

The authors are studying the high-speed operation of static induction thyristors (SITs) for the purpose of their application to pulse power generators with pulse forming lines (PFL). As a result, switching time depends on gate voltage, applied voltage to the SIT and on output resistance. In the case of an applied voltage to the SIT of more than 3 kV and an output resistance of 50 ohm, a switching time of 50 ns was obtained. The authors also propose a simulation circuit of the magnetic switch using a trigatron switch.
