“…The direct discharge type, pulse transformer type, Marx generator type, and vector inversion type are the four basic capacitive energy storage HVPPS topologies that are used in current designs [1][2][3][4][5][6][7]. A comprehensive comparison of these four topologies is presented in [1].…”

“…The difference between the two categories is found in the pulse width. Whilst typical reactive element based topologies are capable of producing pulses that last for hundreds of microseconds, the practical pulse width of transmission line based topologies is limited to a few microseconds [1][2][3][4][5][6][7].…”

This paper presents a novel solid-state and high power pulse generation technique that is suitable for a wide range of pulsed power applications. The technique, termed as multi-level pulsed power converter, can be considered as a hybrid of the direct discharge type and the Marx generator but with considerably less complexity in both control and circuitry. It has the ability for generating pulses with flexible amplitude and duration similar to that of a Marx generator, and unlike the direct discharge type requires no voltage balancing and snubbing circuitry. As voltage balancing is inherent to the technique, the timing between switching events is not critical to balance the voltage stresses and as such the driving circuitry of the converter is relatively simple. The validity of the proposed technique is verified by presenting both theoretical analysis and simulation results of a 3-stage, 3 kV converter.

“…Research on the use of semiconductor switches for the XRAM principle was carried out using GTO thyristors as opening switches by Michael Kanter's group in Israel [7][8][9][10]. This work has been discontinued, but some new results on using GTO thyristors for inductive storage can be found in [11].…”

XRAM generators can be used for powering pulse loads demanding peak power ratings up to the gigawatt range, such as magneto-forming devices, ETC (electrothermal-chemical) guns, high-power microwaves, and railguns. They are a valid alternative to power capacitors being currently at the limits of their technology. In order to improve the XRAM generator in terms of efficiency, the German-French Research Institute of St. Louis (ISL) investigated in cooperation with the G2Elab the use of high-temperature superconducting coils for an XRAM generator. Moreover, as the XRAM switching principle can be integrated into a superconducting magnetic energy storage (SMES) system, a superconducting XRAM generator has the ability to hold its energy available on demand for a longer time than currently employed high-density power capacitors. Our three-stage superconducting XRAM test case reached a maximum charging current of 200 A, discharging a magnetic energy of 84 kJ at 600 A peak current into a 27 mΩ load during a 34 s long discharge. This is the first report in the literature on successful experiments with a superconducting XRAM generator.
