“…Illustration when G1 is short circuit As mentioned before, the R 1 breaks, the output voltage of the Marx generator is 2.8 kV, as shown in Figure 6. Then, the R 1 , R 2 , and R 3 are changed by resistor of 1 MΩ 1 W. By using (3,4), the current flows through R 1 can be limited until 0.75 mA with power loss of 0.5625 W. Finally, with no load condition, the marx generator can produce impulse output voltage of 6.8 kV as shown in Figure 7.…”

“…Marx generator is a circuit with multi-stage voltage multiplier [1,2]. Since the Marx generator has many applications in various fields, it has been attracting many researcher`s attention, for example development of 6-stage Marx generator with 100 kA output and 12-stage Marx generator with 5 kJ output [3,4], switch-capacitor cells used for solid-state Marx generator to produce -4 to 4-kV amplitude is presented in [5], pulse-forming network based Marx generator was reported in [6], and output voltage characteristics based on spark gap breakdown voltage was evaluated in [7]. On the other hand, the Marx generator is also useful for charging storage capacitor (SC) of voltage-current impulse generator.…”

In this paper, a Marx generator voltage multiplier as an impulse generator made of multi-stage resistors and capacitors to generate a high voltage is proposed. In order to generate a high voltage pulse, a number of capacitors are connected in parallel to charge up during on time and then in series to generate higher voltage during off period. In this research, a 6kV Marx generator voltage multiplier is designed using gas discharge tube (GDT) as an electronic switch to breakdown voltage. The Marx generator circuit is designed to charge the storage capacitor for high impulse voltage and current generator applications. According to IEC 61000-4-5 class 4 standards, the storage capacitor must be charged up to 4 kV. The results show that the proposed Marx generator can produce voltages up to 6.8 kV. However, the storage capacitor could be charged up to 1 kV, instead of 4 kV in the standard. That is because the output impulse voltage has narrow time period.
