Hey guys, what would be the best and easiest way to add a zero to full voltage adjustability feature such as a rheostat to an electro luminescent power supply that I am using to charge a capacitor bank with? I will have a few Seriesed electroluminescent power supplies which look like small ice cubes and I am guessing based on what Steve Connor said are probably blocking oscillator based power supplies. They will of course be rectified to charge my capacitor bank for my flashlamp driven laser. So I want to be able to adjust my charge voltage, the power supplies will all be fed with a 12 volt battery. Is it as simple as adding a high-power rheostat in between my batteries and EL power supplies? Or does it get more complicated than that? I am planning to series 9 of them, since they each step up 12 V to 100 V AC. Of course they will all be fed together off of the 12v battery, and the rheostat or whatever you guys recommend would throttle up and down all of them together… I am just not sure if something as simple as a rheostat on the power supplies 12v input wires would work. I know I was not able to use a simple rheostat with NST's on a different laser project… In the alternating current world I had to obtain a variac.....Thanks a ton ahead of time!
