Compact pulsed generator based on ceramic capacitor

A compact pulsed generator based on ceramic capacitor is designed. Its circuit is theoretically calculated and the effect of the main parameters on the output waveform is analyzed. A circuit model of the generator is established for validation with PSpice software, and the simulation results agree well with the calculated results. The generator can produce an adjustable high voltage pulse with the parameters of output voltage 100~200 kV, pulse width 30~40 ns and rise time less than 10 ns. The generator is a no-liquid pulsed generator with ceramic capacitors as the energy storage components and SF6 as insulated dielectric. It has characteristics of compact construction, small volume and light weight.
