Gary could you possiably give me a idea of the AC mains amps drawn from this transformer if I can get 20-25V DC under load and 20 amps? The info I found saya bout 2amp AC. That would be in a 100% efficient transformer.But I know that no transformer is 100% efficient.If a transformer were 100% efficient the power transfer ratio would be 1 to 10 or 1amp AC in for 10amps out thru secondary. Larger transformers are more efficient than small ones, and are usually only about 95% efficient. The max amp rating for 10 gauge wire is say 20 amps. So.. Assuming that my transformer is 50% (I think it is a little higher) then at max amp draw what doesn't exceed the rating of the wire. I would be drawing 110V 4amps AC, from mains into the primary coil. My thinkin from all this is that the transformer primary doesn't care what kind of AC it gets be voltage controlled or phase controlled As long as it is still AC,and is still movin in the coils primary. I think that an AC controller with a 5 to 10amp rating would work just fine. Tho I am currently the high bid on a 110 AC 5amp variac This will be the backup should the controller idea fail.

Taking into Account the Power Losses in the DC Filtering, I would say close to 5 Amps @ 115 volts.

Gary, I lost the capacitors was out bid by 50 cents.While I was at work. any way I'm sending you a e-mail, O GREAT KEEPER OF CAPACITORS (That I need badly). Oh, I was wondering if a 25 amp 50 V bridge will work. I think you have answered this already: Re: AC Voltage Control « Reply #12 on Feb 24, 2007, 7:09am »

Hi Gary, I got the Pony Express started today.I wonder how long it takes to get to you if the horses stay fresh?

Gary , I thought I would post this here The frequency generator this guy uses looks familiar. Its Near the bottom of the page. blog.waterforfuel.com/ He said not to bother you about it ,so I won't . I have a variac Or I will, soon as they get my money-order. Its a panel mount control .Superior Electric Company T441 EP1803 Pri V. : 115 Max output: 3 Amp. Dial reads 0% to 100% of max. output voltage. Size: 4" x 4-1/2" x 5" I need a inexpensive source of 10 gauge magnet wire. but only need 30 ft. Any Ideas. Here in Mississippi, electronic parts, and magnet wire are aliens. People say "Whats That".

Sorry I do not know of Any Sources for that wire in your Area. But you should also look for a Square Wire.
OR you could use a Thin Copper Strapping, Instead of Wire. ** Too Difficult to Explain this Here, But could Possibly send you a Picture in an Email.
Yes that is My Circuit on his Site. I Sent him a Note reguarding Copyright Info and STEALING the same. Especially Without him Actually Posting a Link to My Article!

Yes e-mail pic .also I guess thats why he suggested that no one should contact you, or mentioned your name for that matter. It seem he is going to sell your circuit in a kit form. Or was the above link is now dead.

You Need to send me an Email and Ask for this. I will than Reply to it.

Ok, my Boss at work had a roll of copper foil flashing 50' X 6" wide. He wrapped some tape around one end and cut me off a 1" wide roll using a chop saw (miter saw). Gonna rewind secondary using this foil flashing.I believe this should be easier than the 10 gauge wire. Should make the transformer more efficient, and I should be able to bring my voltage back up to 30 V area.

Chemlec, Would it be ok to use the copper foil picture you e-mailed me to use on my projects page (OurPower) to help describe the foil rewind ?

Yes if you Want. But its Really Not a Good picture. How About This: Its about 2 Volts. (No Load, Open Circuit Voltage.) Short Circuit Current is about 650 Amps Instead of Wire, This is Flattened 1/2 Inch Copper water Pipe. (Soldered Together in L Shapes, because it would be Nearly Impossible to Actually WRAP IT AROUND.) But Copper or Brass Foil also works well for Quite High Currents. Take care.....Gary

Thats a strange lookin critter. I dubbed it " The Frankinformer" on My Projects Page (OurPower). So now for the real question, Whats the story behind this little monster? That thing looks capliable of powering a parallel designed hydrogen cell. with that high amp output.

That thing looks capliable of powering a parallel designed hydrogen cell. with that high amp output. Too Low of Voltage For Hydrogen, but possibly useful as a Spot Welder. I was just playing, but I need some Carbon Rods for it.
