Abstract : This invention relates to a high voltage pulse generator of the Marx type, in which capacitors are charged in parallel and discharged in series. Amongst the many techniques for producing high voltage pulses, the Marx generator is probably the best known and most widely used. For the combination of short risetime and low output impendance (i.e. high power), large energy, high efficiency and waveform flexibility -- the Marx principle is peerless. In response to the recognized need for a Marx generator capable of a high repetition rate, I have investigated Marx circuitry using modern thyratrons as the switching elements. Because of the relatively high voltage trigger requirements of spark gaps, Marx circuitry developed for these devices has concentrated on achieving a balance between hold-off reliability and triggering schemes that produce an orderly erection mode, so that predictable output pulses may be realized. High repetition rate capability, low voltage trigger requirements, and high reliability are well known thyratron characteristics when used in a conventional manner. However, particular problems arise with the use of thyratrons in a Marx circuit, such as both external and internal arcing, because of progressively increasing overvoltages.
