Summary form only given. A compact pulsed power generator with an inductive energy storage system is investigated. The energy transfer ratio into the load is considered by generic calculations, which confirmed the need of a high fuse opening resistance. Long and thin wires are suitable to generate the high voltage as a fuse opening switch. The generator circuit parameters are optimized by numerical analysis, taking into account the stored energy in the inductor at the beginning of wire vaporization and energy consumed during wire vaporization. The generator is designed for high voltage applications. Although the output current is low because of the low initial charging energy, the voltage multiplication factor is, accordingly, high. The inductive pulsed power generator consists of a Marx circuit, an inductor, and a thin and long exploding copper wire. An output voltage up to 800 kV and voltage risetimes of 15 to 40 ns are experimentally obtained.
