Hi,
I’ve got an enormous problem trying to find out what I need to feed my HHO generator.
First I thought using 2 or 3 ATX power supplies in parallel so that I can obtain about 60 amps out of the 12v terminals, but after thinking about it for a while I noticed that this would lead some problems, due to I won’t have exactly 12,000v in each output, so with this currents the only thing I could do to avoid problems would be using one diode (a big one) in each output, and I still doubt about if it would work find. These are the ATX power supplies I’m talking about:
2 x http://www.limitepc.com/fuente-alimentacion-bmove-500w-p-1565.html
3 x http://www.limitepc.com/fuente-alimentacion-bmove-micro-400w-p-1680.html
Then I read about PWM with frequency adjustment and all that and I decided that this would be better, but I still need a DC power supply. I’ve made some research about PWM circuits, but I can only find some schematics of low-power PWM and a lot of people or companies that sell heavy duty PWMs specifics for HHO generation.
Need help! I don’t even know where to start…
