“…A silicon-controlled rectifier (SCR) was also used to trigger a pseudospark in a KMAX-FRC pulsed power system [6] with an 8 kV trigger voltage and 85 A current with a current rise time of ∼ 2 µs [7]. Other high-voltage pulse forming techniques have also been mentioned [8][9][10][11][12][13][14].…”

Pseudospark switches are widely used in pulsed power applications. In this paper, we present the design and performance of a 500 Hz repetition rate high-voltage pulse generator to drive TDI-series pseudospark switches. A high-voltage pulse is produced by discharging an 8 µF capacitor through a primary windings of a setup isolation transformer using a single metal-oxidesemiconductor field-effect transistor (MOSFET) as a control switch. In addition, a self-break spark gap is used to steepen the pulse front. The pulse generator can deliver a high-voltage pulse with a peak trigger voltage of 7.8 kV, a peak trigger current of 63 A, a full width at half maximum (FWHM) of ∼ 30 ns, and a rise time of 5 ns to the trigger pin of the pseudospark switch. During burst mode operation, the generator achieved up to a 500 Hz repetition rate. Meanwhile, we also provide an AC heater power circuit for heating a H 2 reservoir. This pulse generator can be used in circuits with TDI-series pseudospark switches with either a grounded cathode or with a cathode electrically floating operation. The details of the circuits and their implementation are described in the paper.

“…A 300 M shot durability is one of the desired requirements for a laser IFE system. Solid state pulsed power systems have been built since the late 1970s [16,17], and they utilize high voltage bipolar junction transistors (BJT), insulated gate bipolar transistors (IGBT), metal oxide semiconductor field-effect transistors (MOSFET), siliconcontrolled rectifiers (SCR) and other thyristors [18][19][20][21][22][23][24][25][26][27][28][29][30]. These pulsed power generators are typically used for low energy, high rep-rated laser systems [31,32] and high voltage/low current applications [33,34].…”

A unique all solid-state pulsed power system has been tested at the Naval Research Laboratory that produced 200 kV, 4.5 kA, and 300 ns pulses, continuously for more than 11,500,000 shots into a resistive load at a repetition rate of 10 pps. The Marx has an efficiency of 80% based on calorimetric measurements. This pulser is used to evaluate components and advance solid state designs for a next generation solid-state pulsed power system to drive an electron beam pumped KrF laser system for inertial fusion energy. The solid state pulser, designed and constructed by PLEX LLC, consists of a 12 stage Marx, coupled with a 3rd harmonic stage to sharpen the Marx output waveforms, a main magnetic switch, a compact pulse forming line used as a transit time isolator, and a resistive load. Each Marx stage uses an APP Model S33A compact high voltage switch that consists of 12 series connected thyristors. A life test on individual thyristors showed operation of > 300 M shots at 20 Hz without failure.
