“…H IGH current pulses with amplitude of several hundreds of kiloamperes can be widely used in the fields such as high-power lasers, inertial confinement fusion [1], and electromagnetic launch [2], [3]. Capacitive, inductive, and kinetic energy storage methods are viable for these applications, and many works are dedicated to comparison of these methods [4].…”

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.
