Pulsed Power Assemblies

For many pulsed power applications, semiconductor switches can offer advantages over alternative switch technologies. These advantages include; Increased number of operations and general reliability, Improved waveform shaping and pulse control, increased repetition rate and higher current pulses.

Dynex Pulse Power Stacks

The choice of the semiconductor device is critical for correct and reliable operation. Dynex has a wide range of thyristor types, including some which have been specifically developed for high di/dt pulsed power applications. In addition to this Dynex have many years experience in providing specific assemblies for custom Pulsed Power requirements. 

Applications

The Dynex range of pulsed power systems are typically used for:

  • Connection of energy storage to low inductance loads
  • Crowbars for by-passing / protecting a load
  • General thyratron and ignitron replacement
