Spiral Flux Compression Generator (FCG) based self-contained pulsed high voltage source

The design of a self-contained, high-voltage power source, based on a spiral FCG, is described. The diameter of this multi-sectional spiral coil is 50 mm. The external diameter of its aluminum alloy armature is 26 mm with wall thickness of 2 mm. The liner is filled with cast and hot-pressed high explosive (HE) pucks. w A 32 J capacitor is used to seed the magnetic field in the FCG's spiral coil. The seed source capacitor's charge voltage is used to control the initial FCG energy. The operational seed source charge voltage is 30kV. The spiral FCG drives a pulse forming-unit, containing an inductive storage unit, an explosive wire opening switch, and an output spark gap. This 143 mm diameter and 600 mm long self-contained, pulsed energy source has the following output specifications: output voltage of 450-500 kV and electric energy in the pulse of 1200 J.
