PWM plans/schematics?

[dagronmaster]

just type d14 in on the search on the above site it will take you to it.

Hey all!

Been doing some research and yet Google and the interwebs have failed me.

I cannot seem to find a readily available Pulse Width Modulator for my HHO project. I wish to construct one...

You are best off joining this group:
http://tech.groups.yahoo.com/group/workingwatercar/
The schematic for the PWM-F board are available, but that for the PWM-G
is not. You would need to buy the pcb. But you will get a great deal
of help and support to build the 101 plate unit which gives 100lpm
from 20amp at 12 volt !

In the meanwhile, try this:

100 liters per minute on 240 watts?

I hope someone sure has video of that somewhere or has built and tested one for proof of concept...

100 liters per minute on 240 watts?

Yes.
20 amp comes out of the supply, and 32amp from the board to the unit!
Visit the group. The PWM board also has a toroid with complex windings on it.
Need I say more? It is a serious item to build, with 100 cells, each one
insulated from its neighbours, with 6" x 6" SS plates, 316L, each flat and
parallel to the others to a tolerance of one thou. It is about resonance in
an impedance matched system, with 42.8khz going in with another feed
and octave down, and a third an octave lower still.

Ok now what about a regulator or PWM to stop the excessive drain.

This is the pwm i use in my hho setup. I bought it here http://www.extremehho.com . I have noticed the excessive heat at the terminals is now gone and it can finally control it. The built in amp gauge is what sold me on this one.
My next step is to hook up a temp gauge for my cell and i also plan on buying a Scangauge II.
