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.
