Abstract

Abstract

This paper aims to improve the output waveform of pulse forming network (PFN) -Marx generator and get output waveform of short rise time and small ripple factor. Firstly, characteristics of the single stage PFN are studied by simulation, including the impact of single stage PFN terminal capacitance, inductance and PFN terminal impedance on output waveform. The complete simulation model of PFN-Marx generator is established. Using coupled inductor as isolating inductor and using discrete inductor as isolation inductor are studied. The simulation result shows that using coupled inductor as isolating inductor can make charging waveform of PFN more consistent. A small PFN-Marx generator is built. The difference of output waveform of gas switch in PFN-Marx generator under different atmospheric pressure is studied. The result shows that increasing air pressure is beneficial to decrease the rise time of output waveform of PFN-Marx generator.
