High voltage generation from inductive pulsed power generator using a Marxcircuit and an exploding wire

High voltage output up to 800 kV with voltage risetimes of 15 to 40 ns is s uccessfully generated by a compact pulsed power generator (60 x 120 x 150 c m(3)) with an inductive energy storage system. This pulsed power generator consists of a Marx circuit, an inductor, and a thin and long exploding copp er wire. The circuit parameters including an exploding wire are optimized f or a high voltage generation, avoiding a re-strike of the wire. It is shown that the ratio of the energy in a storage inductor at the beginning of wir e vaporization on the energy consumed during wire vaporization is essential in the production of a high voltage.
