IGBT based discharge circuits

NBU-1012 discharge circuit

NBU-1012 is a general-purpose discharge circuit. It forms on the flashlamp quasi-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.

NBD-0505-PWM discharge circuit

NBD-0505-PWM is a discharge circuit with PWM (Pulse Width Modulation) technology implemented. It forms on the flashlamp true-rectangular pulses with the characteristics as below:

  • Flashlamp voltage - up to 500 V
  • Flashlamp current - up to 500 A
  • Pulse width - from 1 ms to 100 ms
  • Max. average power - 2 kW

Module includes embedded inductance coil (80uH) and small capacitor bank (2mF/800V) as well as simmering and triggering circuits.

Free-discharge functionality with 800V/800A characteristics is also available either as a separate output (by default) or as an operating regime (on request).
