Description

Inductive pulsed power generators apply coils as powerful short time energy storage which is an ordinary mean to deliver pulses of high power to loads like electromagnetic accelerators¹. This article deals with the design, simulation, construction, electrical characterization and a pulsed stress test of a modular toroidal coil. The coil was made from 180 D-shaped copper discs and has an inductance and dc-resistance of 1 mH (@ 50 Hz) and 6 mΩ. Its height, diameter and weight are 0.4 m, 1 m and 1 ton, respectively. It is designed to store more than 1 MJ of energy. The coil is segmented into 20 sub-coils with corresponding interfaces whose number of windings can be varied in order to allow its use in different current amplifying topologies like the XRAM circuit or pulse transformer.
