摘要: High energy physics, particle accelerators, and commercial semiconductor metal treatment processes require reliable, high power, variable pulsewidth, flat top, voltage pulses at power. New for food sterilization, waste treatment, pollution control, medical diagnostics are also being developed which pulsed The technology needed to enable solid state voltage, power systems is now available. It has been demonstrated that electronics can bring strong benefits design including: (a) efficiency>90%; (b) low component cost; (c) very average pulse densities (>10 MW/m/sup 3/ peak power); (d) multimegawatt-level power; (e) levels from 1-150 kV; (f) current 10 A 1200 A; (g) repetition frequencies (PRFs) of 30 kHz above (up 400 demonstrated); (h) rise fall times as 250 ns; (i) lengths (1 /spl mu/S DC); (j) reliability.
