SOS-based generator with output voltage of 200kV and repetition rate of 2000Hz

An all-solid-state nanosecond generator has been developed and tested in Northwest Institute of Nuclear Technology. The generator is based on SOS-technology and is designed to deliver pulses with FWHM of 40 ns and amplitude up to 200 kV at 2 kHz repetition rate into a load in burst mode. The average output power is 13 kW. The inductive storage, the Semiconductor Opening Switch (SOS) and the magnetic pulse compressor work as the power amplifiers. The magnetic pulse compressor pumps the SOS. A primary charging unit is used as the generator input. The magnetic pulse compressor and the SOS are the key components of the generator. The material of the pulse transformer core is FeSi and Metglas. Two SOS-180-4 diodes are used in the generator in series. This unit has the operating voltage of 360 kV and cuts off currents up to 2 kA about 10ns.The design of generator, its circuitry operating principle, and experimental results obtained have been described.
