before that the device is loaded with series 600 watts light https://youtu.be/fyLWDJ1Uejo?t=1m17s
That is not 600 W light, but 100 W light (0:49). And hard to say, that is real input amps, because ampermeter not desinged to meashure good 0.5 A curent.

yah you are right 4.5amp is the value in the video that is when he add the 2 kw heater in the bottle you see https://youtu.be/fyLWDJ1Uejo?t=1m27s
He add not 2 Kw heater, but shorted turn. They asume, that on it is disipating power 2 KW.  ;D  I think about 50 W. So no meshuremets, that is real power disipating on that shorted turn.

Bold is my coments.

Here my yesterday video meshurements of this transformer without diode bridge. Secondaries conected in series and gose directly to load 1 K resistor 3-5 W maybe. I try yesterday many variations with many resistors (39 omh. 117 omh and others) and frenquencies and in all cases not get overunity with my transformer. Some specifications of my that transformer I write in my one prieviuos comment.

OU as a Cristmas gift

Christmas greetings to all and mr "bass man" Sandy !

Transformer type 1; See pic 1, 2
Test See pic 3

I took two fat ferrite U-cores and four smaller television fly back cores (2017) http://www.energeticforum.com/306841-post622.html.
One of the fat core and two of the FBC:s only acts as an "I" !!
I have TWO input coils in parallell and the output coils in series .

The Input coils had 2x200 turns and output 2x137 turns. Load resistor = 2744 Ohm (certainly not optimum) and phase & current resistor at input = 2 Ohm.

Television fly back cores : KÖNIG ELECTRONIC FAT100, Ferrite=? Smooth blank ferrite
Big U-cores : EPCOS 93x76x30 mm, Ferrite N27

I have made test sequences from 1 kHz to 6 kHz.
Input voltage just below 2 Volts (1.98V mean)

Load resistor = 2744 Ohm.

Current at 1 kHz about 8.5 mA ----> 6 kHz about 1.6 mA.

Input Phase at 1 kHz about 84.0 degree ----> 6 kHz about 89.4 degree.

Performance: 1kHz = 71%, 2kHz = 92%, 3kHz = 109%, 4 kHz = 135%, 5kHz = 171%, 6 kHz = 237%


Input calc. : V x A x cos ==> V x A x (cosinus of the measured degee value)  . . Gives Input power in Watts.

Output calc. : V sqr/R ==> V x V/R. . Gives Output power in Watts.

Power factor (%) : Output power in Watts. / Input power in Watts. x 100

Pat. pending

@seaad

The bad surprise comes when trying to loop a device. The devil is in the detail.
Did you loop it?

Seaad, 2 Volt x 1,6 mAmpere = 3,2 mVA or 0,0032 VA : what is actually your power/Kg density ratio of your concept ?

Hi Arne,
Roughly a good year has passed since you mentioned first this transformer setup.
Have you managed to refine your measurements? 

Maybe building an 6 kHz or so oscillator to drive the transformer input (embed it into an oscillator) and this way
measuring the DC input to the oscillator could eliminate the ever problematic measuring of the phase angle.

Hi guys

I have only made some tests with a special H-brige, with extremely low idle current, driving a tuned high voltage transformer.
Mainly for testing my type I + II transformers  with a higher voltage input. The COP remained the same.
After that I have been busy with some house and garden projects.

hi seaad

very interesting results with your multicore!

i have an old multicore i made, inspired by the early Jensen design (which was a long time before Thane Heins BiTT)

as you can see from the photo below it has a common winding on the 2 narrower core loops, but i can remove the winding, separate those loops and rewind a primary on each to emulate your design (the core on the left is another, thicker toroid seen from sideways on)

i see that both you (and Jensen) have used AC drive but i'm more familiar with pulse operation, so i think i'll try that first


good luck with your tests, thanks
np

Hello seaad,  probably you heared about Heinrich Kunel and his "static magnetic generator",       
https://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&II=12&ND=3&adjacent=true&locale=en_EP&FT=D&date=19820128&CC=DE&NR=3024814A1&KC=A1#

he also wrote about "his device multi-fold cascading" up to MW-output range. Electrical  transformer coupling   how easy/ difficult in financial costs , especially if to include electrity output kind , DC or AC or pulsed AC, ? ----------------You ,seaad,are real experimenter, not only theorist :----------------
So my thinking and this related my question:---------------- transformer overload protection https://en.m.wikipedia.org/wiki/Inrush_current
each electrical device has for some pulse cycles inrush current and /or inrush voltage ,up to 100 times the nominal value,  so how are you/will you treating this short but to overcome barrier,which kind of " bridge/ glider" ? Inrush limiter ? For each cascade/couple  step a battery/ capacitor bank?

H. Kunel: Yes i have tried that with some gawky experiments. No luck so far.
But I also made many experiments with the split-trafo types without good results first, until suddenly! > 100%. (above my probes, scope uncertainty)
Much of the effect comes from the right core material type (I don't say mine are optimum here)
   See: http://www.energeticforum.com/307037-post642.html
 And the core size ratio.

Inrush voltage is not an issue right now. The important thing now is to bring down the need of Kilo-Volt to the primaries.

I thank you for the answer, but the question was not specific the Kunel-device related( this only stated as example how to treat with great numbers and couplings with several " inrush phase" connections) )  it was and is a geral question:what is the physical and financial cheapest and easiest way to treat this "inrush phase" between couplings in electrical devices ?!f.e.: from a battery to - 1.connection and inrush step - an inverter to - 2. connection inrush step - a motor ......by consumer "no-load up to full load" conditioning!variable " soft drive" arrangement ?-------------------------------------------------------------
