NBU-1012 discharge circuit

NBU-1012 is a general-purpose discharge circuit. It forms on the flashlamp quazy-rectangular pulses with the characteristics as below:

  • Flashlamp voltage - up to 1000 V
  • Flashlamp current - up to 1000 A
  • Pulse width - from 50 us to 100 ms

NBU-1012 also includes a built-in simmer supply module and all the neccessary flashlamp triggering circuits.

NBU-1012 discharge circuit is designed for simplification of solid-state laser systems development. Module forms flashlamp pulses of quasi-rectangular shape using the energy stored in external capacitors bank. Module includes IGBT, its driver, protective circuits, simmering and triggering circuits, discharge resistors and controls.

Let us emphase, NBU-1012 isn’t a stand-alone solution. For proper operations it requires capacitor charging power supply and capacitor bank as well as some minor parts and controls (see also the picture below).
