i can save you the trouble, if you could choose between 120 volts at 1 amp which is 120 watts, or 12 volts 10 amps wich is 120 watts, you would use the 12 volts 10 amps even though the power output is the same, amps does more work.

so you can choose 1 amps to get 120 watts using 120volts

or you can choose 10 amps to get 120 watts using 12 volts

even though the output is the same, you will get more hydrogen at lower volts more amps.

2V is just enough for electrolysis. After I power off the circuit, cell still keeps about 1.5V charge.

i say use 3 coils, and pulse none at the same time. this can be very complicated but you will find it is well worth the complication.

Car alternator is the best to do this job but need to test and find suitable inductor for different speed, that is the challenge. Hope we are going in right direction now.

Kumaran, I think the 3V is very nice to have, because the cell will get hotter with higher volts.

What the circuit concerns, Hydro is talking about a new 3 phase pwm and chokes. That connected to one cell.

I am bussy making a drawing, but I cannot find a normal drawing software with normal ic pictures.

I use ExpressPCB software (free) to draw the circuit. The software is still lack of many component. I had no choice but draw the new component. Actually I've tought about 3 phase long time ago. Yesterday, I was testing my old 3PH circuit (bread boarded) which was used for Bob Boyce resonance drive. One of the phase is not working and I will rectified the problem by today.

My idea is not actual 3 phase (120 degree). I will use 3 different inductor with 3 PWM. I will adjust each phase PW and frequency to produce 1A output which totally depends on inductor used. Then I switch on each phase one by one and see if any significant changes in input and output amps and also gas generation. Using this method, there will be clashes between phases but just wanted to see what the difference can it make to cell and circuit.

What you made is where I and Hydro are discussing about for a while by msn now.

We wanna pusch amps into the cell to. Just like you did in above schematic.

So, if you use 3 pwm's. Every pwm is 120 degrees out of phase. You get a 360 degree phaseshift, just like the alternator.

If you end up with pulsing 3 coils, you have an optimum result.

As soon as I have the schematic finished, I will send it to you.

Yesterday, my friend gave me an old car alternator. I still think of a way to turn this alternator using speed controlled motor. I did some experiment on RotoVerter using 3PH motor previously. Not sure if I can find high speed DC motor and the speed is controlled with variable transformer. I know one of my friend has permanent magnet DC motor.

I still believe series cell (Bob Boyce design) together with this 3PH circuit will produce much better results. I will do that experiment also to confirm. I remember Bob did say he was using less than 4A to produce 6LPM using resonance drive (not really sure). Probably this is the method he used but with fixed frequency.
