Building a simple High Voltage Power Supply out of disposable camera capacitors
Posted on 2014-02-04
I need to know if I can build and use a bank of capacitors to create my own High Voltage Power Supply (I need to produce 10 to 20 kV). Pulse is ok..I don't need to have it give off a sustained current nor do I expect to have the Voltage setting be variable. I have a son who is working on a science project for school; it's an ion engine (a "lifter" in point of fact). My wife helped him build the triangular lifter using wire, tin-foil and balsa sticks. Now it is time to hook it up to an energy source and I didn't realize that we needed a high-voltage power supply (yes, very short-sighted on our part...not involved early enough). So, I do have a box full of used disposable cameras (each has a relatively powerful capacitor, which I've pulled out and used on other projects). The capacitors are each rated at 330wv 80microFarad. If I can just get the 10 to 20 kV out of them for a half-second on each charge, I be happy. That's enough to display what he wants to show. Anyone know how to do this?
