Ccmpact Sized Marx Generator: A Review

Abstract

This paper describes the theoretical study for a simple Marx generator geometry which consists of n phases according to the proposed circuit using MOSFETs, inductive loads and many others that can deliver maximum voltage up to n times cyclic prior voltage with some minor disadvantages. The utmost usage of using the semiconductor devices is to increase the system flexibility, reliability, efficiency and performance and consequently decrease the power losses. The proposed circuit consists of N stages and each in case of semiconductor devices used IGBTs or MOSFETs, diodes, and capacitors, inductors and resistances are also used. Also, the proposed paper also highlights different types of N stage Marx generators. Multiple capacitors are connected in parallel and then rapid discharge takes place through each spark gap; breakdown occurs when voltage is greater than supply. As the proposed circuit is capable of producing high voltage from DC voltage each stage that gives an elevated yield of approximately up to 450–800 V DC (based on network and arrangement) for which info was taken as to make it fundamentally flexible for the bipolar all-solid-state Marx generator circuit. This repetitive generator is valuable as it is capable of controlling the output and thereby consequently the pulse width and generating the high voltage pulses. In the proposed circuits, the productivity of each stage depends on the operating frequency, rising and falling edge of output pulses, rise time, fall time and the repetition rate that gives rise to bipolar pulses, selection of capacitors and timing of discharge and the closeness with the power supply or the switch with the charging power supply and the resultant waveforms quantities were additionally considered. The Simulation or experimental analysis were done with the assistance of many software programs.
