Multistage Impulse Voltage Generator

Abstract

The project is designed to generate High impulse voltage using Multistage or Marx generator principle and
combination of Cockcroft Walton voltage multiplier circuit by using multi stage resistor and capacitor stacks.
Principle is to generate a high impulse voltage pulse using a number of capacitors in parallel to charge up during the
on time and then connected or discharged in series to develop higher impulse voltage during the off period or negative
cycle. This principle or aim is used to generate impulse voltages in the range of KV’s in real-time for testing the
insulation and capability withstanding impulse voltage of the electrical appliances like transformers and the
insulation of the power carrying lines. This project contains the combination with Cockcroft voltage multiplier circuit
for the generation of the high dc voltage for input source for Marx generator. This project is practical and highly
feasible in economic point of view, and has an advantage of researching and testing equipments for higher ratings
and development.
