HHO Transformer Help

[aperry0501]

Hi everyone

I am having trouble with a step up voltage transformer that I have built to go in line with my Pwm controller. I have 200 turns of a 26 awg wire on the inside primary. The secondary has 1200 turns of the same size wire. After tuning the pwm to get about 120 vdc after the bridge rectifier. But when I hook up the tubular Meyers style cells, the voltage drops down to 6 vdc or so. The primary side has 4 ohms. The secondary side has 25.5 ohms.

Do I need to change the primary side size or more or less turns?

I am also experimenting with the Voltage doubler that sirHOAX demonstrates on his Youtube vid. Would this be a more efficient way to raise the voltage so I can then run it through bifilar coils and then into my cell.

Any suggestions would be greatly appreciated!

try using distilled water for starters

I have used 2100 VDC and of course the voltage across the cell will drop,if your supply is current limited. If you were to apply 12oVdc or in my Case 2100 VDC with no current limit your water would boil instantly if you use just electrolysis due to the resistance in your water. Of course it all depends on your Waters conductivity thats why I use only distilled water .With that at least you will set a Standard.
If you want to see higher voltages across your cell you have to achieve resonance within the entire circuit .A good example to follow is here:http://jnaudin.free.fr/wfc/index.htm
There are many links and theories and those like Daniel Dingle and lately
the fellow from Shri Lanka will not reveal their secret and Stan meyers died with it.
I like many others hope to get more data from those confirmed sources.
If not well keep experimenting ,trial and error may get you there.
I wish I could sound more positive but I am in the same boat as all others.

Hi there aperry,
If your transformer has DC current in either primary or secondary, then it could be possible that there is magnetic saturation in the core.
Please read the following reply i gave to Gazza who was working on one of stanley Myers circuits with DC current flowing through the secondary windings.

I do not know if this is happening in your core, but it is possible. Also read Professor's note a little further down in the paragraph talking about Chokes in Myers circuit and using resistance in the secondary winding to limit current. That is if you are using the same Myers circuit as Gaza was using in that post. Click on Gazza's thumbnail and see if it is the same sort of circuit as yours.

I mentioned DC current in the transformer, but also note that a low enough frequency will be like DC to the transformer.

Designing transformers for just AC use, is generally a lot easier, but when it comes to C, E, Toroidal or closed loop ferrites (eg "o" shape) to handle DC current, then it can be tricky, and for some of those cores, practically unusable for DC unless an impractical number of turns and low enough current were used. If it is the case for you that the core is in magnetic saturation due to DC current, then inductance would be much lower, which is a very good reason for such a substantially lower output voltage. In which case, i would suggest one of two things;
1. Getting a complete transformer designed for DC current, and using it within its ratings of frequency and DC current. These are not common by the way.
2. DIY transformer; For the core material, use a long ferrite rod core, or if you have some junked EI transformers, use just the "I" laminations as the core. Or you could just use any ferromagnetic iron you can find, such as nails, or welding rods. The drawback of the DIY option is a much lower inductance than what a closed loop core can give.


Good luck in your explorations
