Repetitive 200 kV nanosecond all solid state pulser with a semiconductor opening switch

A compact 200 kV, 1 kA, 40-50 ns, 30-300 pps pulser has been developed. A distinctive feature of this pulser is that it uses an all solid state switching system. As a final power amplifier the semiconductor opening switch (SOS) is used. After the SOS has operated at a load of 220 /spl Omega/, a 215 kV pulse is formed which has a half-height duration of /spl sim/40 ns. The pulse energy is about 6 J. At the pulse repetition rate of up to 300 pps the instability of the output pulse parameters is tenths of a percent and is determined by the instability of the input supply voltage. The dimensions of the pulser are 650/spl times/600/spl times/320 cub. mm, it weighs /spl sim/80 kg. The pulser developed can be instrumental in conducting research aimed at searching for and refining novel technologies under laboratory conditions.
