For all-electric mobile systems, inductive pulsed power generators represent a very attractive alternative to capacitive generators. This is due to their high energy density, low charging voltage, short charging time and to the fact that they can easily be combined with modern high-power (lithium-ion) batteries. In particular, storage coils embedded in a so-called XRAM circuitry can be used to produce a current pulse, the amplitude of which is a multiple of the charging current supplied by the batteries.In this contribution we summarize the development of XRAM generators at ISL up to now and present some unpublished results. Special emphasis is laid on semiconductor-based opening switches and coils with high energy density. Both are core elements of XRAM generators and have to be designed for very high currents (several tens of kiloamperes).

“…But in the case of conventional coils, the energy can be stored only for a very limited time due to the resistive losses in the windings. This is more than twice of the energy density of modern capacitors which is 3 MJ/m 3 [28]. It is known that the coil with the best inductance per GPW is the Brooks inductor, which is a solenoid coil where the inner radius is half the outer radius and is equal to the height of the coil (R out /2 = R in = h).…”

“…Considering the volume of the inductor, a volumetric energy density of 7.1 MJ/m 3 can be stated. This is more than twice of the energy density of modern capacitors which is 3 MJ/m 3 [28]. The source capacitor C 0 is charged to 1.0 kV, providing a peak charged current of 5.5 kA for inductor L 1 with a charged time of about 4.5 ms.…”

This paper describes a compact high storage density inductive-capacitive storage module. The module is based on high-power opening switches using inverse current commutation with semiconductor devices commutation principle and a high storage density Brooks inductor. These opening switches, being able to switch-OFF pulse currents up to 14.5 kA by the countercurrent subcircuit, make use of the general property of a standard high-power thyristors impedance transition from closing state to blocking state. The experimental results show that with the primary capacitor and counter-current commutation subcircuit charged voltage 3 and 2.5 kV, respectively, the charged current of the Brooks-type inductor is about 14.5 kA, with a charged time of about 4.5 ms. The output peak current of the inductive storage module is about 21 kA. The total stored energy is about 54.9 kJ while the energy density of the inductor is approximately 6.69 MJ/m 3 , which is not including the primary storage and commutation unit.Index Terms-Brooks inductor, inductive storage system, opening switch, solid state.
