PVX-4150 1.5kV Pulse Generator

PVX-4150 1.5kV Pulse Generator


The PVX-4150 pulse generator is a direct-coupled, air-cooled solid-state half-bridge (totem pole) design, offering equally fast pulse rise and fall times, low power dissipation, and virtually no over-shoot, under-shoot or ringing. It has over-current detection and shut-down circuitry to protect the pulse generator from potential damage due to arcs and shorts in the load or interconnect cable.

All control and protection logic circuitry, support power, energy storage and output network are incorporated into the PVX-4150. It can be connected directly to the load, and does not require series or shunt resistors, impedance-matching networks between the pulser and the load, or additional energy storage (capacitor banks). All of this is taken care of within the PVX-4150.


  • 0 to ±1500V Pulse Output
  • <25ns Rise And Fall Times
  • >240KHz Pulse Repetition Frequency
  • Protected Against Arcs, Shorts And Load Transients
  • Voltage And Current Monitor Outputs


The PVX-4150 is well suited for driving extraction grids and deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators. Its robust and versatile design also makes it well suited for pulsing or gating power tube grids, Pockels cells and Q Switches, acoustic transducers, microchannel plates, photomultiplier tubes and image intensifiers.
