I am currently working on a coilgun and I have generated a 600:mu:f Capacitor bank at 600V, giving me 108 Joules of energy. I now need to generate that 600VDC. I have been looking online on how to generate the 600VDC, but to no avail. I have worked on High Voltage and Coil Guns before, but I require this high voltage source. I would like to use a small transformer with a high frequency, so I can save on space. I just have to find directions on how to wind a transformer. Any good websites?
hi,
There are voltage doublers and triplers that will give you a few hundred volts.
You could use a bog standard mains transformer, driven by a simple switcher.
Stating the obvious, that level of charge can kill, I know you are aware of that, but ensure that no other less experienced person finds out the hard way.
I am looking for a portable solution (no 120VAC) that can run off 1 and in worst case scenario 2 12V18AH batteries. Total estimated requirements: 600VDC-800VDC at 960uf.
I can wind my own xformer and anything else that is required. its been done before, but I cannot find the circuitry that they did it with.
You want to step up a DC source???
Invert it to AC and step it up like that, because I don't think anyone makes DC to DC converters of such magnitude...
Also take into consideration that Xformers don't like square wave inputs much so you will need to develop a sine inverter...
At least I think that's what would be required, someone back me up/correct me on this...
You could use a couple of mains transformers, providing they have twin 120V primaries (for operation at either 120V or 240V). This will give you about 450V (if you take into account the losses in the transformers) which you can rectify to give about 636V.
Note that the circuit attached is niether isolated nor current limited and touching the live output is likely to kill you, use at your own risk.
Have you consided using a camera flash charger, 1 for each of the capacitors, the can change it up to 330 volts each, you would probably need to change it for higher current, but it would get you the voltage level that you need.
Your making this too big, I need a small PSU yet capable of charging a 960uf 800VDC capacitor bank in a somewhat respectable time (lol no 20 hr charge time)
