Thane Heins BI-TOROID TRANSFORMER

[capthook]

Thane - most excellent to see you here again sharing your work!
I for one missed "hearing" from you and your updates.
How goes the PEREPITEIA?

3mA on a 4A full scale setting  This is down in the "noise" of the meter's capability, and the reading is bound to be inaccurate (you are performing COP measurements here afterall).....
As per the above, the computations and measurements made in the video are not reliable imo.

This is my initial concern as well.

Can I ask a question without being fried and twisted like a morning bacon.

CHECK THIS OUT IT MIGHT HELP...

BTW - WHO DOESN'T LIKE BEING FRIED AND TWISTED "MAKIN BACON"?
BECAUSE...

I have watched your latest video 'BITT 4.0" it's quite interesting, Effectively I see a good PF of 0 on load or non load. We see clearly the sinusoids (Voltage vs Current lag) doesn't moove on load !!! Very good job, thank you for clarification.

Hi,

In july I found a video about BiTT on YouTube, I've read the patents and two weeks ago I started to replicate BiTT. There are my 3 little transformers here... 

The secondary cores are cores with high permeability.
The permeability of the blue "0-core" is 30000 (version A and version B)
The permeability of the brown toroid (version C) is 80000.
I'm not sure about permeability of the primary cores, but it is certainly much smaller...

I use Joule Thief bifilar winding as a primary coil... (i'm not sure if this is good idea, i will try pure AC input...)
The red wire on blue core is for detecting of changes of the magnetic flux. I will cut the "E-core" to "C-core" in version B.

I will try to post some oscilloscope shots next week...

Hi all

Wow Makl very nice set up  any datas already ? thanks for sharing

Yes Tyson it seems that in parallel the wiring is important and if you cross the wiring the output is almost nothing and on the other side it is much better. But of course we are always working with very low power so there might be a lot of other measurements to confirm.

Just for info , i have done a BITT as per Thane's  (Mary-Jo) shematic with insulated fence wire , very easily, it took me about 2 hours to complete the BITT with fence wire and winding .  Here some pix.

First crude test the fence wiring induction seems to be good enough for basic testing.

OK for tonight and tomorrow will add something to speak.

Good night at all and go on replicating
