Confirming the Delayed Lenz Effect

[gyulasun]

Hi Gyula,

I did make a Primary on the 7.5H Ferrite Toroid and tested it. I posted the results back on page 15 on the bottom of a reply to you:  http://www.overunity.com/index.php?topic=11350.msg301782#msg301782

Anyways, it does only normal transformer action. Maybe the effect has somthing to do with the Steel laminations? 

Hi Luc,  sorry I must have skipped over it, maybe this effect manifests at an even higher frequency than 2MHz for this kind of transformer. How high frequency can you go up to with the signal generator I wonder. 
IT is sure the 7.5H winding on this toroidal core has got a much less self capacitance than in case of the MOT's secondary and I am also sure the laminated core in the MOT fails to maintain its permeability in the kHz range and starts diminishing significantly and nonlinearly.

Re on scope numerical display error of 2: yes it could be due to software and the manufacturer should be aware of that by now.
OK on your HV scope probe!

Notice on the first Shot how each 50% duty Phases of the H-Bridge to the Primary seem to only effect the Secondary at the beginning of each Phase change. The Secondary seems to have a ringdown like if the rest of the of the on time of the Primary is wasted. Notice on the second Shot (Secondary on load) the voltage on the load drop again like if most of the 50% phase on time is not doing anything to hold the current on the load.

Yes you noticed it correctly. This is the usual behavior when a transformer is driven with square wave: during the on time of the pulse the pulse amplitude does not change hence no current can change in the coil (pulse amplitude is horizontal)  so no induction can take place during this time.

Here is a variable duty cycle pulse generator for driving H bridges from Groundloop:
http://www.overunityresearch.com/index.php?topic=819.0 I suggest using also the CMOS type LMC555C or TLC55C timers, they work up to about 3MHz.
This would be good for futuristic too

WE LOOKED AT USING FERRITE LAST YEAR FOR THE BiTT WITH A LICENSEE IN EUROPE BUT THE POWER FACTOR WAS 1 ON NO-LOAD WHICH WAS NOT USEFUL AT ALL AND I THINK LUC AND I TRIED METGLAS AT OTTAWA U IN 2008 - WHICH WAS GIVEN TO US BY CARL, DO YOU REMEMBER LUC? ANYWAY PERHAPS LUC CAN VERIFY THIS WITH HIS FERRITE TOROID?

WELL CHET YOU KNOW WHAT THEY SAY... "IF THE SHOE FITS"AND WE DO NEED EXPOSURE BUT MORE THAN THAT PEOPLE NEED TO BE REMINDED OF WHAT REAL HUMAN COOPERATION LOOKS LIKE.

MY POSITION HAS ALWAYS BEEN THAT THE WORLD OUGHT TO HAVE A "MONTREAL PROTOCOL ON ENERGY ALTERNATIVES WITH GLOBAL COOPERATION SANCTIONED BY THE UN" WITH THE PRIMARY OBJECTIVE TO SAVE THE PLANET RATHER THAN EXPLOITING THE GLOBAL WARMING ISSUE TO CAPITALIZE FINANCIALLY AS AL GORE AND HIS BUDDIES AT KLEINER PERKINS CAUFIELD & BYERS ARE DOING.     

THE MONTREAL PROTOCOL PROVED THAT IT CAN WORK AND WE ARE ALL PROVING IT HERE AS WELL.

The Montreal Protocol on Substances That Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances believed to be responsible for ozone depletion. The treaty was opened for signature on September 16, 1987, and entered into force on January 1, 1989, followed by a first meeting in Helsinki, May 1989. Since then, it has undergone seven revisions, in 1990 (London), 1991 (Nairobi), 1992 (Copenhagen), 1993 (Bangkok), 1995 (Vienna), 1997 (Montreal), and 1999 (Beijing). It is believed that if the international agreement is adhered to, the ozone layer is expected to recover by 2050. Due to its widespread adoption and implementation it has been hailed as an example of exceptional international co-operation, with Kofi Annan quoted as saying that "perhaps the single most successful international agreement to date has been the Montreal Protocol".It has been ratified by 196 states.

HOW DOES ONE START A NEW FORUM TOPIC FOR THE INFO BELOW? Thanks Thane

OK THE ABOVE STATEMENT IS BALONEY, SO...

"MONTREAL PROTOCOL" FOR ENERGY ALTERNATIVES AND WORLD BENEFITTING TECHNOLOGIES

POTENTIAL DIFFERENCE INC. IS STARTING A NEW IP COMMERCIALIZATION COMPANY CALLED E-MOTION TECHNOLOGIES INC. WITH THE AIM OF ASSISTING IN THE WORLDWIDE EVALUATION AND COMMERCIALIZATION OF EMERGING TECHNOLOGIES WHICH CAN BENEFIT THE PLANET EARTH AND PROVIDE A FAIR FINANCIAL RETURN FOR ALL PARTIES INVOLVED.

THE DEVELOPMENT OF NON-EXPLOITIVE BUSINESS PRACTICES AND MUTUALLY BENEFICIAL SYNERGIES BETWEEN VARIOUS TECHNOLOGIES WILL ALSO BE ONE OF THE KEY MANDATES AS WELL.

IF YOU HAVE A TECHNOLOGY WHICH IS AT THE PROTOTYPE STAGE WHICH NEEDS TO BE EVALUATED, FURTHER DEVELOPED OR COMMERCIALIZED BUT YOU DON'T HAVE THE RESOURCES, ARE UNAWARE OF POSSIBLE SYNERGIES WITH OTHER TECHNOLOGIES OR THE MARKETING ROUTES TO DO SO PLEASE LET ME KNOW.

KIND REGARDS

idea for a test:
maybe to make DC of the output (maybe like diode bridge + capacitor filter) and measure it under different loads
