Solid-State Repetitive SOS-Based Generators Providing a Peak Power of GW-Range

Summary form only given. The paper describes high-current nanosecond generators providing a peak power of GW-range. The first generator of S-5NS type has output peak power of up to 4 GW, output voltage of 0.4-1 MV, pulse length of 8-10 ns, and pulse repetition rate of 300 Hz in the continuous mode and up to 1 kHz in the burst mode of operation. The average output power is up to 30 kW at the pulse repetition rate of 1 kHz. The generator is outfitted with an all-solid-state system of energy switching. The output pulse is formed by a semiconductor opening switch comprising SOS diodes. The electric circuit and the design of the generator have been described. Experimental results have been given. A device for elimination of prepulses across the load has been proposed. Testing results and numerical modeling of the device have been reported. The second pulser presents a multifunctional SOS-based generator of SM-6N type that has been developed in different versions. At GW-range of peak power the generator provides pulse width of 20 -30 ns in long pulse version, and 7 -10 ns in short pulse version. Typical value of the output voltage is 400 to 800 kV. The generator operates continuously at pulse repetition frequency of 300 Hz, and up to 2 kHz in the burst mode of operation. The electric circuits and the design of the generator, as well as testing results have been described.
