This manuscript introduces the concept, physical operating principle and studies on a new and unique two stage forming fuse (TSFF) with interstage spark gap commutation and presents its application for forming high power pulses of extreme parameters. The paper classifies TSFF performance and compares it with conventional single-stage forming fuses. The conclusions are supported by analytical and experimental studies in laboratory conditions. The design of the TSFF prototype as well as the applied measurement methods and test stands are also presented. The developed technology of the TSFF enables the achievement of unprecedented parameters of high-power pulses with overvoltages reaching 800 kV and pulse power of tens of GW in a very compact design. The unique properties of the TSFF enable its efficient integration with a wide range of energy sources, even with very limited current rising steepness or limited output voltage, which has not been possible so far with conventional single-stage forming fuses. The proposed system can be easily scaled, while ensuring much greater flexibility of applications.

This article presents the electrical and mechanical design of a compact 13-stage 0.5-MV Marx generator operating at a pulse repetition frequency (PRF) of 100 Hz. The fast-switching process of the generator is based on spark gaps, operated under pressurized air and leading to the generation of an output pulsed voltage with a peak of 0.5 MV and a rise time of 15 ns when operated on a 300-load. Corona-stabilized electrodes are installed near the main gap of the switches to improve their operational stability and increase the PRF. To ensure compactness, the Marx generator is housed in a cylindrical metal vessel with a height of 92 cm and an outer diameter of 34 cm, having a total volume of 74 L. A highly accurate simulation using both PSpice and CST software packages was used to predict the impulse waveform at the output of the generator and to help in optimizing the generator design. The tests show a good agreement between the experimental data and the theoretical predictions.
