I built a xenon tube flash for my camera that uses a 320v, 220 micro farrad capacitor. Currently it's a simple manual flash that just dumps all the cap energy into the flash tube when it is triggered and then I wait for it to charge back up before I can use the flash again. I want to have options now where I can flick a switch making it only use 1/3rd of the cap's full energy so I can use 3 small flashes before needing to recharge. I know I need an IGBT that pulses the energy from the cap to the tube.
So when I look for an IGBT what info am I looking for from the data sheets? I'm unfamiliar with IGBTs so I know how they work and what they do but how do I find out if it can output the energy level I need and handle the input current from the cap? I know IGBTs can usually have a wide range of output currents so is that achieved from some kind of input current to tell the IGBT how much to output?
Like I said, I'm using a 320v, 220 micro farrad capacitor and want to use 1/3rd of the full energy from that at a time.
