HI All I'm looking to see if anyone can supply me or make me 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 |

35A 600V Bridge rectifier on a heatsink plus a handful of 400V Electrolytics? Non isolated and crude as fuck but it will give you a NON ISOLATED 300V or so at plenty of current. 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 charge not voltage, and the bond strength in H2O is not THAT strong. Regards, Dan. |

Hi Thanks for your reply, sorry I didn't mention adding a voltage regular. I tried the bridge rectifier but by adding a regulator as I needed to adjust the voltage for variable gas output, it trips the breaker. A normal angled regulator is not compatible with a bridge rectifier. I don't have really good knowledge on electrical or electronics. The simple solution I found and been told was using an AC to DC converter but a heavy duty one I can find was only available in the US. When the hydrogen generator was hooked up to the bridge rectifier, running at 6 amps, it was showing 260 to 270 vdc from mains. Thats why I needed a converter capable of handling at least 300vdc. |

You haven't mentioned the most important thing yet: budget. But I wouldn't bother cooking up one yourself unless you consider it a learning experience. Get one of these and call it a day: http://be.farnell.com/ea-elektro-automatik/ea-ps-8360-10r/power-supply-1ch-360v-15a-adjustable/dp/1607347 |

Better of using a variac ahead of your bridge rectifier, preferably with an isolation transformer too. Even with the isolation transformer it is still very dangerous. :-- :-- :-- |
