Hi everyone,

since now I learned how to correctly calculate Pin and Pout thanks to Thane and Gyula I decided to test the BiTT.

From all the paying around with the BiTT I can tell you it's a very different Transformer then the one I built.

One of the main difference is there is no ideal Frequency it works better at. The 50Hz to 200Hz range is all the same and Frequencies above that the output starts to go down in a linear way.
The other difference is Load, the more the load the more the Phase shift. Mine, the more the load (short is best) the more I can drop the Frequency and still have a Frequency that I get Zero Phase shift loaded or not.

Here are my Power Calculations from the Scope data. Shunt is 10 Ohms and S1 & S2 loads are 150 Ohms each. Test is done at 60Hz.

First scope shot is no load

Second scope shot is with loads and Interestingly enough it has the same 76.5 Phase angle then my Transformer.

Third scope shot we can see all the data and I calculate 0.0246713136 Watts in

Power out is 0.001944 Watts on S2 and 0.0015876 Watts on S1 for a Total of 0.0035316 Watts out

Looks to be a little under the 14.5% efficiency range

If Thane or anyone else see a problem in my calculations please point them out

@Luc, have you tried two different loads at the same time on the BIT? So lets say S1: 30 Ohms and for instance S2: 150 Ohms? My guess is that this will amplify the counter Lenz effects between the two secondaries, playing inside the special BIT transformer... Of course all this without reflecting to the primary coil.

Hi Luc,

Can you show a photo of these setups BIT/GTL90? Just curious...
Your calculations are correct for the BIT.

On your GTL90 I wonder if a power factor correction could be done like Overunityguide mentioned this afternoon?
To do it, you need to know the input coil self inductance and choose a capacitor with the same reactance at 60 Hz the input coil has at 60 Hz. Then connect this cap in parallel with the input coil, this way the input impedance will be real with no phase shift between input current and voltage instead of the present 90° shift.

Humm ... I thought that 90 degrees Phase shift was the best scenario. I achieve it and now you say something else is better.

Inductance of my Primary is 220mH

HEY LUC,

DON'T LISTEN TO THESE GUYS THEY ARE ALL ON CRACK! 
POWER FACTOR CORRECTION IS GENERALLY DONE ON A BUILDING AS A WHOLE ANYWAY...
SOON THERE WON'T BE A GRID SO THE POINT IS MOOT ANYWAY.

NOW IF YOU STICK YOUR BiTT (WITH ZERO POWER FACTOR) IN BETWEEN AN ELECTRIC CAR'S GENERATOR AND THE BATTERY (PF = 1) AND YOU WILL HAVE REACTIONLESS (LENZ FREE) TRANSFER OF POWER WHICH IS WHAT THIS THREAD IS ALL ABOUT. 

ACTUALLY YOU CAN USE THE BiTT BETWEEN THE BATTERY AND MOTOR AS WELL.

CHEERS

PS 1
GOTOLUC 90 TRANSFORMER PHOTOS PLEASE?

PS 2
NOW THAT YOU HAVE A PF = 0 PRIMARY POWER CONSUMPTION = Ip(squared) x Rdcprimary

PS 3
NICE SCOPE WORK BTW (EVEN IF I DO SAY SO MYSELF )

MY ELECTRONICS PROFESSOR PETER CARILLO IS SMILING DOWN FROM HEAVEN RIGHT NOW SEEING THAT I ACTUALLY LEARNED SOMETHING IN HIS CLASS AFTERALL).

Here are the new Scope Shots with the GTL 90 Transformer connected to 120vac 60Hz Grid Power

Power in Reactive = 0 Watts

Power out = 0.74 Watts

Please note that I changed the Shunt Resistor to 1 Ohm since Input Voltage is much higher then the Singal Generator Output was.

First Shot is GTL 90 Transformer with 120vac 60Hz Grid Power no Load (phase check)
Second Shot is GTL 90 Transformer with 120vac 60Hz Grid Power & 10 Ohms Load (phase check)
Third Shot is GTL 90 Transformer with 120vac 60Hz Grid Power & 10 Ohms Load (complete view & data)

One interesting thing about this Transformer is when I connect the 10 Ohm load to the Secondary there is Zero effect to the Primary Phase degree. You can see that between the first scope shot (no load) and the second scope shot (10 ohm load).

Please post your comments

I'm posting these scope shots just for the fun of it.

I can adjust the Voltage to Lead the Current by 97 degrees which give a Negative cos of -0.1219

However the output starts to drop

I calculate -0.7878 Watts returned to Grid and 0.2133 Watts on the 10 Ohm Load

Let me know if I calculated it right
