“…However, several researchers applied superconducting coils in small scale demonstrators [41], [43], [54], [70]. Some of them applied the superconductor itself as opening switch by letting it quench on purpose [42], [44], [75]. A 20 MJ/1 MA conceptional design for a high temperature superconducting coil pulsed power generator is presented in [76], [77].…”

Abstract-This literature review addresses inductive pulsed power generators and their major components. Different inductive storage designs like solenoids, toroids and force-balanced coils are briefly presented and their advantages and disadvantages are mentioned. Special emphasis is given to inductive circuit topologies which have been investigated in railgun research such as the XRAM, meat grinder or pulse transformer topologies. One section deals with opening switches as they are indispensable for inductive storages and another one deals briefly with SMES for pulsed power applications. In the end, the most relevant inductor systems which were realized in respect to railgun research are summarized in a table, together with its main characteristics.

“…Even if the S 3 EL concept makes it possible to operate the launcher at much lower current than classical powering, the required current is still in the tens of kA range, which is difficult to achieve with HTS conductors. A possible solution to obtain high current output is to use the XRAM current multiplication principle [17,18]. The idea is to charge several inductances in series and to discharge them in parallel to sum up their currents.…”

Electromagnetic rail launchers (EMRLs) require very high currents, from hundreds of kA to several MA. They are usually powered by capacitors. The use of superconducting magnetic energy storage (SMES) in the supply chain of an EMRL is investigated, as an energy buffer and as direct powering source. Simulations of direct powering are conducted to quantify the benefits of this method in terms of required primary energy. In order to enhance further the benefits of SMES powering, a novel integration concept is proposed, the superconducting self-supplied electromagnetic launcher (S 3 EL). In the S 3 EL, the SMES is used as a power supply for the EMRL but its coil serves also as an additional source of magnetic flux density, in order to increase the thrust (or reduce the required current for a given thrust). Optimization principles for this new concept are presented. Simulations based on the characteristics of an existing launcher demonstrate that the required current could be reduced by a factor of seven. Realizing such devices with HTS cables should be possible in the near future, especially if the S 3 EL concept is used in combination with the XRAM principle, allowing current multiplication.

“…This circuit structure generates the current pulse by applying the methodology of the Marx generator. It has been demonstrated by parallel operation of normal conducting storage inductors and superconducting storage inductors [2]- [4]. However, using this method to achieve high-level current amplitude requires a lot of coils, and that will make the system more complex.…”

We have been developing an inductive pulsed power supply (PS) consisting of several superconducting pulsed power transformers with Marx generator methodology. Each of these pulsed power transformers consists of a copper secondary winding and a high-temperature superconducting primary winding. In order to obtain a high-voltage impulse, the Marx generator should be charged via the parallel connection of capacitors and discharged via a series connection. In contrast, this superconducting pulsed PS is excited in series connection of superconducting primary windings and discharged in the parallel connection to obtain a large pulsed electric current. Our preliminary experiment result showed that the process of one transformer module was correct. In this paper, the characteristics and simulation results of the superconducting inductive pulsed PS are described.
