Abstract

An overview is given about semiconductor components and solid state switch assemblies for repetitive pulse applications. These switches are designed for use in power modulator applications. A newly developed switching system is presented which can be used up to 40 kVDC, current capabilities of several kA, and very high current rise rates which are also in the several kA/μs range. Pulse repetition frequencies up to 1 kHz are possible if the devices are combined with adequate cooling. The switches are designed as alternative, or replacement of thyratron and ignitron solutions because lifetime is several times better. By using a modular platform technology, a large variation of power levels can be reached. The presented switches include triggering system, and, where required, also include power supply and air or water cooled heatsinks.
