The circuit reminds me of a CDI (capacitive discharge ignition) by the way it charges up a capcitor and uses a scr to dump the energy into the primary..

My thoughts as well!

did you used horvath circuit? i like those big bubbles, dont know exactly how they are geting that big... perhaps the concave electrode favorites the bubble agregation?

I used SS razor blades in cork before , I could only say it was the sharp edge that produces more bubbles than the flat but then it has to be facing the other plate as the shortest path

That was just strait dc 3 amps.
I am now going to build that electromagnet and i will build a similar circuit as Horvath is showing in his patents.
Its about 300v and 20 amps being dumped into a coil. He wrote in his patents how many Gauss you should measure in the cell....

If you read the patents, you can see that the electrodes are nickel plated. The hydrogen is collecting some how in that layer.
I think that is part of the reason of those bigger bubles.
Maybe the sharp edges help, but the surface of the inner electrode are also not smooth. Like it was sandblasted.

cheers!

Your electrodes are nickel plated? Is not very hard to plate nickel... What material your electrodes are made ?  Nickel wont plate directly on stainless steel it needs a stricke layer...

soft iron core with nickel plating.
That way, the magnetic fields from the transformer aka electromagnet areable to penetrate the waterbath

need help

I need your help....

I must design a transformer.
Here are some details that i have.
Core is laminated silicon steel
Primary input 22 amps at 300v
Sec output : 30000v amd 220mill amps
Core shape is rectangular bar
Frequency is 10khz
Duty cycle is 10% max

How many turns amd what wire diameter do i need?

Please shoot....

What is the size of the core area? And window?

Im not sure but i think you would need a 6kva core to be able to sustain that output

The formula for the tuns is simple but the power is more complex... The first problem with high voltage is high turns makes high reactance so to have decent current output with a low voltage drop you need low inductance so lower turns higher core size


I use it like this for pulse on off

Volts/Area/bmax/frequency/2 = turns

Bmax is 1.2 for laminate steel some quality may be higher
