Abstract

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.
