Abstract

Summary form only given. A presentation is given about semiconductor devices used for on-off pulse applications and used in a 12 kVdc / 3.2 kA / 10 Hz solid state switch assembly. The switch assembly is built-up with IGCT technology and used for long pulse (1.6 ms) Klystron modulators. The design was made in 2002 and successfully implemented in the Tesla Test Facility (TTF) at DESY in Hamburg / Germany. The components and switches are in the position to switch and interrupt safely up to 4 kA. The presentation will inform about the IGCT devices, switch development, construction, production and commissioning of the complete assembly. Also reliability figures will be presented and the last 4 years of operation have shown that the switches are extremely rugged.
