Abstract :
A solid state switching system is presented which is designed as high reliable, long life, low maintenance product for short repetitive and high di/dt pulses. The solid state switch uses special designed semiconductor devices with integrated fast triggering circuits which are powered by one closed loop current source power supply. Blocking voltages of over 30 kV are possible by stacking several devices in series connection. The solid state system has no environmental restrictions and can be used in any position.
