Rapid Capacitor Charging

EHT has modified 5 kW nanosecond pulsers to rapidly charge larger capacitors (up to 4 nF) for a specific customer application. The unit was designed to charge capacitors up to 4 nF in 100 – 300 ns (depending on capacitance). The pulser was tolerant to shorts for up to 3 seconds.

Continuous Operation

  • Output Voltage: 0-2 kV
  • Output Capacitance: 0-4 nF
  • Pulse Repetition Frequency: 0-100 kHz

Burst Operation

  • Output Voltage: 0-4.5 kV
  • Output Capacitance: 0-4 nF
  • Pulse Repetition Frequency: 0-500 kHz
  • Number of Pulses in a Burst: 0-125
  • Burst Repetition Frequency: 0-50 Hz
