Abstract— This paper discusses and simulates the Compact High Impulse Marx DC Generator (CHIVMG). The high impulse voltage (more than 30kV/cm) is generated by this compact Marx generator. The deep analysis and design of this generator is discussed. After derivation of the transfer function of the Marx generator, stability and its ability to generate high impulse voltage is thoroughly discussed. A 15 stages prototype is built to verify the design, and the high impulse voltage is generated. With a peak of 1 kV and rise and fall times of 10 ns and 1 ns, respectively, the input voltage is configured as a pulse voltage. The Marx generator’s final spark gap has a peak voltage of 50 kV. Additionally, the capacitances’ charging time constant is roughly 700 ms. The capacitance discharges with a time constant of roughly 320 ms. Together with the chosen parameters and the discussed mathematical model, these temporal constant values accord quite well. Finally, the Marx generator’s instantaneous power consumption ranges from -4.4 Watt to 2.8 Watt because it is a high impulse voltage, low current generator.
