Heavy duty AC to DC converter required
Heavy duty AC to DC converter required
HI All
I'm looking to see if anyone can supply me or make me with an AC to DC converter ?
I had basically searched through the internet and electronics and electrical suppliers looking for a minimum of 16 amp converter from 240vac to 300 or over vdc. It is for running a DC hydrogen generator.
Thanks everyone

300V DC at 16A is 16 X 300 = 4,800 Watts. The maximum output from a standard 3-pin 13A socket is 13 X 240 = 3,120 Watts. You would be trying to draw more than could be supplied, even if you ignored losses in the converter.
You will need to get in touch with your electricity supplier or contractor for either up rated sockets and wiring, etc., or think about having a 3-phase supply installed.

Thanks David, It works fine when it was running at 270VDC from a bridge rectifier, had it running for 40 minutes several times. It doesn't run at 4800w but just in case it ever goes near to that wattage. I could only get one from the US capable of converting up to 600vdc but preferably from UK or the EU but I don't want to use a variac transformer as its too heavy and bulky.

This is the type of converter I'm looking for but not available in the UK.

Re: Heavy duty AC to DC converter required
I am rather confused by your reply. Just what "works fine" at 270V DC? What current was it supplying or drawing? Are you serious in your first post of "a minimum of 16A"? However you arrange things, you will always (in a UK domestic setting) have the restriction of a maximum wattage from the mains socket.

35A 600V Bridge rectifier on a heatsink plus a handful of 400V Electrolytics?
Non-isolated and crude as but it will give you a NON ISOLATED 300V or so at plenty of currents.
300V strikes me as a really weird voltage for electrolytic H2 production, usually, a couple of volts at large currents is more like it, after all, H2++e− is all about the charge, not voltage, and the bond strength in H2O is not THAT strong.
