Just wondering if this PWM drive the cell directly, or do you use a step up transformer to rise the voltage. From my research about Meyer's electronics, the step up transformer is used, he gets the current down to 0.5 amp at one stage with still a great outcome of Gas. Since watts is volts x amps, stepping up voltage makes sense. But his cells used aluminium pipes within pipes for electrodes. Having 9 x 18" pairs, 1 in the middle & 8 eqi distance around it. See Ravis duplication.
Cool, I have been asking around on electro-tech about your self-regulating PWM. I'm getting pretty close to figuring something out. I'll message you with the link to my thread on electro-tech
working with high voltage pulsed power - depending on the rise time requirements, you might run into smearing of your waveform with a parallel arrangement. If you don't need seriously fast switching times (hundreds of MHz) then I'd use an IGBT. I think you mentioned bipolars in another video - IGBT=Insulated Gate Bipolar Transistor. Handles tons of voltage and scads of current. Think Giga and Terawatt pulses at 100ns, 5KV, 100 ohm load. about 50 amps pulsed. Bzzzt!
so do you have to have a degree in electrical engineering to build effective hho devices to install in your vehicle.

You need the knowledge of what your doing to do anything.

excellant advice mike... but it is so much fun pushing the parameters!

Wow, 500 amps!

direct. xfmr coupling makes it AC.

I was under the impression a square wave in will give a square wave out.

Could you post the schematic of the additions so we could add them to our own PWMs

It's like an FET and Bipolar hybrid right? I've never worked with them but their spec sheets are impressive.

What does your waveform look like on the o-scope

I hope that means more then it did to me.

Hi did you try to put more than one mosfet in parallel to double the current handling. I belive that is simpler to do with fets than transistors.

Nice!
Now, show some bubbles.
