High Current voltage booster? Answered
So I have been doing a lot of math for a rail gun, and I finally found out what statistics I need for the capacitor to get the energy needed.
But I may have ran into a problem. The voltage for the system is rather low, but the current is high, so I need a capacitor with something like 60-ish Farads, and 20 V, and of course the ones I find are outrageously expensive. ($2,400!!!)
But I was able to find ones with 70 F but only 2.1 V, but since I need 20 volts I was thinking that I could use a voltage booster, but I am not sure if that would work, or if I can find/make a Voltage booster that can withstand that kind of current (would be something like 67.5 KA)
the other option is find ones with higher Capacitance, which I did, but they are still a bit on the expensive side ($70, and since i need to it comes up to be $140 or so (not as much but still))
So what I wanted to know is whether it would be less expensive to try to find/make a voltage booster, or just buy the $70 capacitors?
I suppose I should also be asking is it even possible to get a voltage booster that can that that many amps, and how easy would it be to make?
Oh almost forgot, another question (which would skip having to solve the others) is: Is there a way I can increase the voltage that a capacitor can take, or increase the voltage in a capacitor bank, or some variation of those? Because if there is, that makes everything easier, but I couldn't find anything on doing that so yeah...
