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).
