you cant measure it like that if you have reactive components .

You need  to measure with a  wattmeter and calculate phase shift to see your true power used .

It would be helpfull if you come with a complete answer with examples, orso.

To be honest, i dont think the comment of the Prof of Turtle and your comment apply here.
The reason is that i always do gas output measurements and compare that with strait dc or simple pulsed dc. You understand that?
In my tests, i see gas output of 60watts with an input of 40watts...
How i know? Because i know how much gas i have on 40watts in as well...

input : 20.8V by 2.06A = 43Watts
output : 17.0V by 4.0A = 68Watts

why don`t you try connecting another toroid coil in between the output and the cell ?

I cleaned up this topic.

Conclusions:

Output FET:  43.8Vrms by 4.22A = 184W
Input WFC:  36,5V by 8.08A = 294W
Output AC Variac: 79Vac by 4.9A =  387W (different set of meters as the other 2 measurements points.)
Gasoutput: ca. 2 minutes for 0.5 ltr
----------------------------------------------------------------------------------------------------------------------------------
Strait DC into wfc:  37.4V by 7.62A = 285W
Output AC Variac: 41V by 9A = 371W
Gasoutput: ca 2 minutes for 0.5 ltr
---------------------------------------------------------------------------------------------------------------------------------
Conclusions:
1.   My meters on the AC side where not identical as the other 4 meters, so a   
                mismatch is very possible between AC power and DC power.
2.   My circuit is a perfect converter for squarewave to strait DC.
3.   No OU or any gains what so ever compared to totall input vs output. (from trafo till
                wfc)
4.   Strait DC still wins against any kind of pulsing circuits.


As you can see, lots of time is again consumed with no results, except the gain of knowledge......

bammer.......

Ah, Steve, there are indeed results.    Knowledge.   

And the pursuit of knowledge necessarily takes time.  Thanks for doing this

Hi Ady,

I had to read back what i did during that test.
It came back after reading, so here is what happend.
I used a variac, full rectified and straited out with a capacitor bank.
That wend into a mosfet and that fet was switching on and off a bifilar coil, with an alternative diode setup, as i send to you by email.
The bifilar coil was hooked up to the cell.
By tuning the pwm, i got readings as discriped. There was a hugh difference on the input of the coil and on the output on the cell.
It looked like OU. However, when i started to measure power on the variac side, there was not such thing.
So, totall power in on the pulsed circuit was never less then i measured on the cell.

This setup worked by only with parallel cells or open platecell. Not with drycell constructions.
Its had something to do with the negative voltagepeak coming off the cell after on puls. That voltage goes back into your bifilar coil.
Together with the little capacitance of that bif coil, you create some kind of what ever…. 
Maybe some kind of bucking circuit?



cheers
Steve
