IGBT based discharge circuits
IGBT based discharge circuits form quasi-rectangular pulses on a flashlamp using energy stored in external capacitors bank. They also provide simmer current during the interval between pulses. By default, NBU-0808 and NBU-1012 include capabilities both for serial and external triggering.
NBU-1012 is a general-purpose discharge circuit. It forms quasi-rectangular pulses on a flashlamp and provides simmer current between pulses.
- Flashlamp voltage - up to 1000 V
- Flashlamp current - up to 1000 A
- Pulse width - from 50 us to 100 ms
- Includes a built-in simmer supply module and all necessary flashlamp trigger circuits
NBU-0808 is a general-purpose discharge circuit. It forms quasi-rectangular pulses on a flashlamp and provides simmer current between pulses. Includes IGBT, its driver, protective circuits, simmer and trigger circuits and controls Both for serial and external triggering.
- Flashlamp voltage - up to 800 V (1000V on request)
- Flashlamp current - up to 1000 A
NBD-0505-PWM discharge circuit
NBD-0505-PWM, a PWM-based discharge circuit, forms on a flashlamp true-rectangular pulses with regulated width and provides simmer current between pulses.
- Flashlamp voltage - up to 500 V
- Flashlamp current - up to 500 A
- Pulse width - from 0.5 ms to 100 ms
- Max. average power - 2 kW
- Free-discharge option with the 800 V / 800 A
The module includes integrated inductance coil (80 uH) and small capacitor bank (~ 1 mF / 800 V) as well as simmer and trigger circuits.
