Solid-State Pulse Generators

Custom pulse generators are available for unique and demanding applications that fall outside the scope of commercial systems. In general, our pulsed-power development projects fall into one of the following two categories:

  • Pulsed-power systems utilizing our spark-gap switches and trigger generators (typically >15 kV and >10 kA), or
  • Solid-state pulse generators employing parallel/series stacks of MOSFETs, FREDFETs, or IBGTs (typically <10 kV and ~100-1000 A),
although an overlap in the current-voltage capabilities exists for these two technologies. Our services are available from concept definition to delivery of turn-key hardware including system engineering, specialized component design and fabrication, and final assembly and testing.

Representative solid-state projects include

  • Very-low-impedance (2.7 Ohm), fast-transition (<20 ns) FREDFET pulser for high-current micromagnetics research1-3 (CP-106),
  • Custom trigger and control consoles for plasma-physics facilities,
  • Fast, two-temperature optical pyrometers,
  • Multichannel delay generators for fire command and control, and
  • 10-kV ion-beam modulator using MOSFETs.
