what should i expect from my pwm?

[hhoexclusive]

i bit the bullet recently and got a meyers pwm built supposed to be exact replication i got the circuit design from a unknown source and had it printed and built and tested by electronics engineer it works but my lpm are down with it on at the moment. how do i go about setting it up properly it has such a large range of adjustment it will take forever to find a sweet point where it works best. hints? have heard water resonates at 926hz should i start there. i also want to use a modified inverter to feed 240 volts dc into it will this be beneficial or just stay with 14.4 volts??

just fitted cell and pwm to car today and after 5 minutes of decent gas production.... fried the pwm mosfet has turned blue and the tracks on the board leading to it show obvious signs of distress. was only using 6 amps too very strange.

From what I've heard PWMs decrease gas production/efficiency (with brutal force electrolysis)

[hhoexclusive]

a pwm should reduce the amps used to make the same amount of gas. i think my problem is my pulse is not on for long enough to get my cell up to speed my production is only down by 9-10% and am using 6 amps instead of 30 to run it. what i wanted to know was, will i be able to use the tuning capabilities of the pwm to get close to or hit resonance and increase gas output? i only use water and no additives in my cell now keeps it safe.

Well it looks like the "supposed" Stan Meyers PWM circuit from an unknown source that has a mosfet doesn't resemble what Stan was using.

Were there any electric motors connected as a rotating transformer?

Does the unit output square wave pulses, or does it have the "ringing" pulses like Stan Meyers drawings?

There are many variables to consider when using any feild effect transistor, the impedence of the load (amount of resistance, inductive reactance, capacitive reactance)

Id Max is the current limit of the drain on the FET

P Max is the maximium power dissipation of the FET

So when designing a "motor speed control" (which is what a PWM really is) the designer needs to at least start with enough information about the load to stay within the range of operation of the output device.

FET's can be connected in parallel to increase the current that can be controlled.

Can you post the schematic of your PWM ?

P.S.
A PWM will just pulse your DC reducing the "on time" in direct relation to the shape of the pulse waveform, if your reactor chamber has electrodes that will help resonate the water molecules you "may" be able to increase your gas output.

Hoping to help...

backtraced through where i got the design it originated from dave lawton and on a oscilloscope does produce a ringing pulse it works fine on a small seven cell but on my 12 cell it was just a bit much for it i think. the fet wasn't the buz350 as reccomended but was of the correct rating. the article i got it from was d14 at the bottom of stan meyers patent. when i say unknown source i mean i've forgotten which site i downloaded it from i started tracking down info for the project early in 07.

Not exactly what you were looking for...

Hi hhoexclusive,

Some things that need to be done with the setup you have would be to include the Meyer's inductors/chokes/transformer setup. There is a thread about Meyer's bifilar chokes under the login "energy" forum that discusses this. From my small amount of experimentation with that circuit, I understand what happened to you. The circuit will work correctly when connected to the WFC through the bifilar choke/inductor/transformer setup. The problem then becomes keeping it in resonance.

Good Luck,

ITF

was quite suspect when the plans said this was a solid state version that didnt need the chokes or toroid transformer. never mind i have got this far making chokes and a toroid to get it working properly just has to be done i guess. the pwm is fine just needed a new fet chip turned out it was a dud.
