Abstract

The key to achieving a compact yet reliable pulse power system lies in the switches. The ideal switch would be modular and scalable thus allowing for mega-volts and mega-amps of current to be switched with nanosecond rise-times. OptiSwitch Technology Corporation (OTC) proposes to develop a revolutionary optically activated thyristor fabricated with conventional, low-risk, silicon processing. With a novel optical coupling system, a 5cm2 switch can block 10 kV and conduct 25 kA with a rise-time of
