Switching properties of series connected static induction thyristor stack

In recent years, various semiconductor switches with ability of high voltage and current are researched and developed for electric power devices. Those merits are a long life time, high reliabilities and miniaturization of components. Our goal in this study is to examine switching properties of series connected Static Induction Thyristor (SI-Thy) stack for the purpose of applying to a pulsed power generator with pulse forming line (PFL). As a result, in the case of 3 SI-Thy's connected in series, almost the same turn-on time (about 100 nanoseconds) was obtained at higher switch voltage (more than 10 kV). Our empirical result shows that the SI-Thy stack enables us to apply it to switch a pulsed power generator. Furthermore, we compared the characteristics of the stack with a simple.
