Confirming the Delayed Lenz Effect

[gyulasun]

DEAR GYULA,

THAT'S FUNNY THEY DID THE SAME THING WITH MY "INFINITY GENERATOR" PROVISIONAL PATENT.
TO TELL YOU THE TRUTH I FORGOT ABOUT THAT APPLICATION.
LET ME ROOT AROUND IN MY FILES TO SEE IF I CAN FIND THE ACTUAL FILING DIAGRAMS AND I WILL POST IT ASAP.

WHAT ARE YOU LOOKING FOR SPECIFICALLY?

ALSO CAN YOU POST THE LINK?

Hi Thane,

Here is a link to your application (Toroid Generator Coil) to the Canadian Patent Office:
http://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/2602439/summary.html?type=number_search

I simply wished to see the Figures to better understand your setup described in the application.

Thanks,  Gyula

Hi Folks,

Regarding the efficiency calculations I think the main power source for this setup is the battery bank, it supplies 62.4V DC voltage and the current taken is about 8.3mA  (83mV/10 Ohm) so this gives a total input power of 0.517W.

If we can agree on this half a watt input power than the the efficiency of the H-bridge is what comes into the picture next and I suppose here it has a 90% efficiency, this reduces the possible input power to the transformer to 0.517*0.9=0.465W.

Now the transformer efficiency is (0.1107/0.465)*100=23.8%  (Note: This depends on the efficiency number we consider for the H-bridge.)

When a load connected to the mains consumes only reactive current, the reactive current has to come from somewhere and it is also the mains, though most watthours meters do not measure it...  hence when you wish to create the reactive current you have to furnish real power first.

@nul-points, sorry but I have to give you 'zero points' for your input calculation. (please don't take it personal)

I say this because you are forgetting one very important parameter which also should be added in your input power calculation.

i agree - my bad - i regarded the i/p as from a single-ended driver, but of course, although Luc has a unipolar DC i/p supply, he is using an H-bridge!

with 32mA RMS i/p current (measured on the 1 ohm shunt) and a bipolar 61.5 RMS i/p voltage (measured across the primary coil) the average power i/p is approx 0.55W

so the transformer efficiency = 0.1107 / 0.55 = approx 20%

DEAR LUC,

YOUR H BRIDGE IS A THING OF BEAUTY BUT

HERE IS MY SUGGESTION...

REPLACE THE PRIMARY IN THE BiTT WITH THE BI-FILAR BECAUSE IT "APPEARS" TO BE GIVING SOME GOOD LENZ DELAY.

THEN RUN THE BiTT WITH 60 HZ SINE WAVE AND SEE WHAT HAPPENS THEN TWEAK THE FREQUENCY TO SEE WHERE YOU GET THE BEST PERFORMANCE.

THEN ONCE YOU HAVE ESTABLISHED SOME GOOD RESULTS GO BACK TO DC STUFF WITH THE AC STUFF AS YOUR POINT OF REFERENCE. 

BUT BEFORE YOU DO THAT I WOULD (INDEPENDENTLY) TEST THE BiTT AS IS JUST TO SEE WHERE IT IS AT AS WELL SO YOU WILL KNOW IF THE BI-FILAR PRIMARY PROVIDES BETTER PERFORMANCE.

Hi Thane,

I agree!

This will be my next step and in the exact way you suggest.

I just couldn't resist to test the Bifilar Coil to see if it worked also in a transformer application.

I'll be out all day today so it will go to Monday or later for results

Thanks for all your help Thane
