Applications of pulsed power

  1. 1. Applications of pulsed power technologies Dr. Sergey Korenev 1
  2. 2. 2
  3. 3. Time scale         Milliseconds: 10-3 sec Microseconds: 10-6 sec Nanoseconds: 10-9 sec Picoseconds: 10-12 sec Femtoseconds: 10-15 sec Attoseconds: 10-18 sec Zeptoseconds: 10-21 sec Ioktoseconds: 10-24 sec 3
  4. 4. Main directions of R&D for PPT 1. Production of max power in pulse. 2. Transfer to short pulses duration (picoseconds, femtoseconds). 4
  5. 5. Main directions of R&D for PPT It related to R&D of:  new capacitor and induction energy storages;  new switches. Capacitors: New materials: solid, liquid for receiving of max electrical field. Induction: Superconductors: High Temperature Superconductors.  5
  6. 6. Reminder Inductive energy storage: WM=B2/(2o) = (1-50)J/cm3 Capacitive storage: WE =.o.E2/2 = 0.01-0.08 J/cm3 Charging unit Charging unit Capacitor energy storage Switch Inductive energy storage Opening switch Transmission line Closing switch Load Load 1st compressing stage 2nd compressing stage 1TW, 100 nsec 10GW, 10 sec Power Power 100 GW, 1 sec 10 kW, 10 sec 100 kW, 1 sec Time Time 6
  7. 7. Switch Perspective directions are next: 1. Semiconductor Open Switches- using forming of plasma in semiconductors, especially in SiC. 2. Vacuum switch with large cross section of cathode plasma. Reduction of induction of plasma channel (10-10 Henry).  Main task is low induction of switch channel. 7
  8. 8. Industrial products      Marx generators with pulse duration from 20 ns to till 100 microseconds. Induction generators with pulse duration from 1 ns to till 1,0 microseconds.. Fast switches ( 5-20 nsec rise time). High current pulsed switches for converters. Diagnostics: High voltage probes, current transformers. 8
  9. 9. Radar Applications    UWB Radars UWB Ground Penetration Radars UWB Electromagnetic Influence Systems – ECM 9
  10. 10. Conclusion  It is short introduction to main applications of Pulsed Power Technologies. 10
