Abstract

Summary form only given, as follows. Summary form only given. We present the study and results obtained with a repetitive Marx generator. The issue of this work was to provide an experimental high voltage repetitive generator to investigate a recurrent switching and fast power supply. To design this generator, we consider the voltage and the energy rise-time of the power supply, the total capacitance and the output voltage of the Marx generator. The power supply characteristics are 6 kJ/s with 40 kV and the Marx generator has 13 stages of 5.2 nF. The gas switches work with a pressure of 3 atm dry air/SF/sub 6/ mixture and can operate at a fast repetitive rate (more than 2 kHz). Even without a triggering system, we obtained an output voltage stability of /spl plusmn/7%. The parameters of the system are in the range of 350 kV peak voltage, 15 ns rise time, 50 ns pulse width and 115 Hz repetitive rate.
