Bipolar silicon high-power semiconductors for pulsed power - devices, applications, limits

For many years, Eupec has manufactured bipolar high-voltage semiconductor devices that, after appropriate modifications, are also suitable for pulsed power applications. This is particularly true for direct light-triggered thyristors (LTTs) with breakdown voltages up to 8 kV and for soft recovery diodes with breakdown voltages up to 9 kV. Presently, Eupec is developing 13-kV LTTs and 13-kV diodes. By using such high-voltage rectifiers, the number of components in applications with several devices connected in series can be reduced, saving money and improving reliability of the total system. Typical application areas of high-voltage rectifiers in the field of pulsed power applications are reviewed in this paper
