Home Electronic Project, Can Use Some Help :)
I'm trying to hack together a few things to make a uninterrupted power supply unit. So far, I've got a 500W power inverter from 12V to 240V, and a car battery. Unfortunately, I also need a power supply capable of pumping enough amps into the inverter and battery to get the whole thing started.
I've tried an old ATX power supply I had lying around (actually several :s and I figured if I can get at least a few amps out of it it'll power ONE computer at least) but as soon as the inverter is connected to the 12V line the power supply shuts down (even when it's not powering anything at all, just the inverter ATM). It's like some sort of safety mechanism, same thing happens if you short two wires across. I know there's nothing wrong with the inverter because I can plug it into a normal wall transformer (which fried as soon as I plugged something into it because the transformer only output 1A ), and it works fine powering a computer on the battery.
Anyone know of a way of overriding this mechanism, or even better, a way of hacking together a cheap and nasty 240V -> 12V 50A power transformer? Maybe splicing two power supplies together, if it's possible?
