Many of my ideas are halted buy an inability to switch heavy currents ( coil gun , multi kilowatt led strobe, exploding a tomato or 25m. of magnesium ribbon) , I realize I also need quite a few super caps which I've already started collecting (Maxwell 3000F). These IGBTs can pulse over 1KA at 1.2KV (mouth waters)... so enough I think, I bought 3 of these cheap on eBay also some TC4422 s which I believe are required to drive them. I found one useful circuit on the web but am still not to clear how to couple them together . For the moment I just want to switch it on and off with a low current.... any help I'll be eternally grateful for......thanks
