Analysis of a Solid-State Switch as Peaking Switch in a Solid-State Marx Generator

This paper discusses about the investigations on the performance of solid-state Marx generator with and without peaking circuits. Ten stages monopolar solid-state Marx generator (SSMG) is simulated in MATLAB and the results are validated mathematically. A three-stage prototype of the Marx circuit is implemented to analyse the delay associate with the switch control circuit. The output pulse rise time is compared with and without the peaking circuit. To attain the peaking action the minimum time required to turn-on the peaking switch is much smaller than the required turn on time of an IGBT switch. Fast switching solid-state devices are required to act as a peaking switch to attain both the peak voltage and reduced rise time.
