I need a high voltage, high amperage power supply Answered
I am in need of a power supply that can give out about 500V @ 13A. I know it's high, but I want it to charge a capacitor(400V, 1000μF, 13A) for my coilgun. I've already tried a flyback charger, but the result was to blow the capacitor up(I think that it couldn't withstand so much voltage, despite the amperege was lower that its threshold). I don't want that to happen again and I want a relatively fast way to charge the capacitor. Also, the power supply needs to be portable.
Another thing: the voltage is not mandatory to be THAT high; the amperage also(let's say...1 or 2 amps...)... However I need DC pulsating current, at 20 kHz
NOTE: I really hope that I'm not asking too much.......
