    Lawrence Livermore National Laboratory has many needs for high reliability, high peak current, high di/dt switches. Solid-state switch technology offers the demonstrated advantage of reliability under a variety of conditions. Light-triggered switches operate with a reduced susceptibility to electromagnetic interference commonly found within pulsed power environments. Despite the advantages, commer... View full abstract»

    The material properties of semi insulating 6H-SiC and GaN have been analyzed in terms of their applications as a photoconductive switch at high bias conditions. Both the switches have similar button type geometry and have been analyzed for breakdown, photocurrent profile, rise and fall time. The laser power and duration for initiating conduction in both the PCSS were the same except for the wavele... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (359 KB) | HTML iconHTML

    A procedure for choosing the dimensions of a photoconductive semiconductor switch (PCSS) for operation at microwave switching frequencies, and particularly at 10.0 GHZ, is described. The critical dimension is the switch length (electrode separation), which must be small enough to force photo-induced charge removal during switch turn-off via sweep out rather than recombination. The switch depth in ... View full abstract»

    Marx generators are used to produce high voltage, high current, short pulses for a variety of applications. High energy Marx generators are typically switched by gas insulated spark gaps, which have short lifetimes, <105 pulses, thus limiting practical applications of the Marx generators. APP has developed optically triggered, economical, compact, 48 kV, >30 kA/mus, 8 kA, and 100 ... View full abstract»

    Vanadium compensated, 6H silicon carbide (SiC) is investigated as a compact, high-power, linear-mode photoconductive semiconductor switch (PCSS) material. SiC is an attractive material due to its high resistivity, high electrical breakdown strength, and long recombination times compared to other photoconductive materials. The PCSS is designed for fast-rise time, low-jitter (sub-nanosecond) operati... View full abstract»

    Silicon-carbide junction field-effect transistors (JFETs) are maturing in performance, reliability, and manufacturability, especially with voltage ratings ranging from 600-1800 V. The vertical channel JFET (VJFET) with extremely low specific on-resistance (< 0.25 Omega-mm2) is now available. In this paper, new results are reported on a two-switch module packaged in a commercially ava... View full abstract»

    Flux Compression Generators (FCGs) are some of the most attractive sources of single-use compact pulsed power available today due to their high energy density output and mobility. Driving FCGs requires some seed energy, which is typically provided by applying a high seed current, usually in the kilo-Ampere range for mid-sized helical FCGs. This initial current is supplied by a high-current seed so... View full abstract»
