Design, Construction, and Testing of an 80-kJ and 2.4-MJ/m3 Inductive Pulsed Power Module for Electromagnetic Launchers

Inductive pulsed power supplies have become a promising option for the power supplies of electromagnetic launchers, because they can reach a good balance between the energy storage density and the power density. This article presents a status for our research work, namely an integrated pulsed power module. The length, width, height, and volume of this module are 0.48 m, 0.3 m, 0.24 m, and 0.034 m
³
, respectively. In the so-far conducted highest energy-level experiment, this module reached 4.91-kA inductor charging current, 77.6-kJ inductor charging energy, and 2.36-MJ/m
³
module energy density. The output current pulse reached 15.0-kA first peak value, 15.4-kA second peak value, and 14.1-ms half-peak value pulsewidth. The performance of this module has been confirmed to be stable and consistent within the range of 0-80 kJ.
