Pulsed Power
and Power Electronics
• Developed novel, high-efficiency, high-energy density, solid state power supplies for DoD and NASA.
• Developed and demonstrated one of the first U.S
examples of all-explosive pulsed power generators.
• Developed a unique university explosives research facility.
• Developed unique high-speed diagnostics with optical and electrical capabilities.
• Investigated novel methods leading to electronically-triggered equipment defeat.
• Developed multi-university cooperative research programs.
• Developed the world’s best-equipped university high voltage, pulsed power, power electronics laboratory.
• Established the IEEE International Pulsed Power Conference that now has more than 600 participants.
• Largest producer of graduate students in the area of Pulsed Power Majority of students finds employment at national laboratories such as LANL, Sandia, Los Alamos, NRL, and defense industry.
Texas Tech University engineers and scientists develop compact, repetitive, high voltage generators that can drive a wide range of devices and systems for military applications These devices and systems include directed energy devices, electronic jammers, electronic upset devices, car immobilizers, non-lethal crowd control systems, and power electronics.
Military forces are faced with new and unpredictable enemy
attacks in the battlefield The Center for Pulsed Power
and Power Electronics utilizes its expertise in generating
very high power electrical pulses to provide troops on the
battlefield with effective, innovative technology This effort
is complemented by investigating the physical phenomena
associated with pulsed high voltage and the development of
compact solid state power supplies.
PURPOSE
Large space simulation facility (vacuum and thermal).
