A high-current nanosecond-pulse generator with a pulse power of up to 1.6 GW, an output voltage of 0.5-1 MV, pulse duration of 40-60 ns, and repetition rates of 300 Hz (in a steady-state mode) and up to 850 Hz (in a burst mode) is described. Its average output power is 30 kW at a pulse repetition rate of 500 Hz. The energy-switching system of the generator fully consists of solid-state elements: a thyristor, magnetic switches, and a semiconductor-opening switch based on SOS diodes.
