Solid State Switch for high voltage sub-microsecond pulsed power

Applied Pulsed Power, Inc. (APP) proposes to develop a solid state switch for high voltage sub-microsecond pulsed power, using silicon carbide devices. The objective of the solicitation is to develop a compact, solid state pulsed power switch capable of switching 20-50 kV, and I > 5 kA with low jitter, fast rise time (~20 ns), L 5 kA with low jitter, pulse length to 1000 ns, and up to 1000 Hz prf using silicon thyristors. These switches are used for applications with pulsewidths >200 ns and di/dt of <100 kA/us. Patented packaging and triggering techniques are used to produce 20-60 kV switches from multiple identical lower voltage modules. We will apply these techniques to silicon carbide devices to produce low inductance (< 1nH/kV) switches with <20 ns risetimes.
