Marx Generator Based High Voltage Using MOSFETs: A Review

TLDR: In this article, the authors have developed a reliable and easy to carry compact 4-stage Marx generator that can produce impulse voltage 4 times of input voltage with some minor losses, which is useful in small scale industries and academic institutions to demonstrate impulse voltages.

Abstract: This paper shows the development of a reliable and easy to carry compact 4 stages Marx Generator that can produce impulse voltage 4 times of input voltage with some minor losses. In addition, three different experimental circuits of DC supplies have been made. The highest output was 100 V DC for which input was taken as the main supply for the experimental and simulated Marx generator circuit. This generator is useful in small scale industries and academic institutions to demonstrate impulse voltages and also to perform testing on insulators and transformers of lower rating in laboratory.  A total of 4 stages of both simulated, experimental Marx impulse generator circuit is designed and the impulse waves are recorded. The simulated recorded impulse waveform, is compared with the standard impulse wave. Both of circuits, the efficiency of each stage was calculated and the percentage of error in the front and tail time was also found out as well as the effects of the circuit parameters on the impulse waveform characteristics were also studied. The simulation was done with the help of Proteus 8 Professional. In this work, the comparison in terms of magnitude of the experimental and simulated 4 stages Marx generator circuit has been carried out.
