OptiSwitch Technology Corporation (OTC) in collaboration with the University of Southern California (USC) proposes the development of a compact, high voltage, and high repetition rate solid-state pulse generator for nonthermal ignition and for other applications including plasma surface modification. The fully solid-state pulse generator module will be based on a design successfully tested in a Pulse Detonation Engine and other combustion ignition and control experiments. This unit will generate a variable 75ns-150ns wide pulse at 10kV-50kV, easily extendable to higher voltages. To satisfy the short pulse requirement of 30ns-50ns an innovative diode opening switch (DOS) stage, initially using commercially available rectifiers, will be seamlessly added to the base unit. Using a 2D silicon process and device simulation program the final DOS will be of a unique and innovative design that does not exist at present. The DOS package of series devices will allow for proper thermal management to meet the 3kHz requirement. In a follow-on Phase II program the DOS devices will be fabricated and packaged by OTC in OTC s silicon foundry.
