“…In the original Marx generator, spark gaps were used to connect the cell capacitors in series, and a resistor and inductors were used to limit the charging current and self-discharge paths [24]. With the improvement in solid state switch characteristics, major progress has been made in the development of Marx generator-type topologies based on semiconductors [25][26][27][28][29][30].…”

A 100 TeV center-of-mass energy frontier proton collider, in a new tunnel of 80-100 km circumference, is a central part of CERN's Future Circular Colliders (FCC) design study. The designs of the injection and extraction systems of the FCC are initially based upon the parameters of the injection and extraction systems of the Large Hadron Collider and a preliminary study of the FCC beam optics and lattice. The injection and, in particular, the extraction systems of the FCC have to be highly reliable. In order to achieve high reliability, solid state switches will be used for the generators of the injection and extraction systems. This paper discusses topologies of these kicker systems, which are presently under consideration.

“…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.

“…Many pulsed power loads are designed for a single operating voltage and operate poorly outside of their nominal envelope. Consequently, laboratory pulsed power systems are typically tuned to deliver a relatively constant voltage over a desired duration [1,2,3]. When attempting to package the pulsed power into a compact form, engineers face the challenges of maintaining the pulse shape, preventing breakdown in the compact architecture, and to a lesser extent, rejecting waste heat in high duty rep-rated systems.…”

-Stacked Blumlein lines with solid dielectric potentially offer a compact pulsed power system for a variety of applications by combining the energy storage, voltage scaling, and pulse forming functions into a single device. By stacking the lines physically, not simply electrically, the line is made more compact because adjacent lines share electrodes. This design does not lend itself to the use of a single switch to commutate the stacked line, and multiple switches are far simpler to implement. The switch jitter and electrical characteristics strongly influence the performance of the line and the stresses on the dielectric. This paper explores the effects of switch jitter, inductance, the resistive decay during closure, and the closed-state resistance on the output pulse and dielectric stresses for stacked Blumlein lines using SPICE simulations. The impact of switch operation on the necessary dielectric strength and the quality of pulse is presented.The suitability of various switch technologies to meet the performance requirements is also discussed.
