Re: [EVGRAY] Triple thick BiTT

Body

Hi Doug,
That shielded wire idea can be used with many different types of
transformers and different situations to get some extra delay.
It's not without some losses too..... it's just another tool for our
arsenal.

To answer what you asked about BITT transformer.

"What I was trying to get at about the BiTT and the backemf forces, is
just what is it that creates that "split" of the backemf force from the
forward-current magnetic force, and for that backemf force to run along
those extra transformer legs leading back to the opposite secondary, and
not route itself back to primary???"

I just try to think of the input flux and the output fluxes separately.
Sure they both absolutely have to share a common flux path at the output
coils.

But we should keep the cause of the fluxes separate in our own mind.

If the load draws no output current then there is no "Back EMF or Lenz
flux" generated.. there is only input flux created by input ac Voltage
source .

If our BITT or other transformer has a  load connected then there will be
an additional large Lenz flux flux generated by the load current itself.


Flux will always take the easiest path just like current does.
If there is a common pathway and two fluxes are travelling in opposite
directions along that flux path, they effectively subtract from each other
even though each one is still present.
(Whilst the electrostatic field at right angles to the flux field will add
to each other).

If we think of the flux pathway as a single horizontal resistor hooked
between positive terminals of 2 batteries with common earth.
Say 1 battery supplies 1.5 Amps Left to Right through the resistor and the
other supplies 1.0 amp Right to Left through resistor then the total
current is only the difference of 0.5 amps Left to Right through the
resistor.

This is called "superposition theorem" and applies equally to flux paths.
We consider each separately then algebraically add them up.

Now say we could temporarily reverse the direction of current from one of
the batteries the current would be cumulative and no longer subtractive, so
we'd get 2.5 amps rather than 0.5 amps.
(sort of what we're doing by timing how long the flux takes to reurn)

We could call one battery the "input flux" generator and the other battery
the "Lenz flux" generator, their causes are separate but their combination
is cumulative in a magnetic circuit.

In magnetics our horizontal "resistance" is called "reluctance" to the flow
of flux.

Like with resistors if we put 2 reluctances or reluctance paths in
parallel.....  the input flux lines will divide between the  2 paths.
The one with the lowest reluctance (or highest permeabitity) will
receive the highest flux and the other path the lowest.

Just like resistors we can use current divider formula to work out how
much....

say flux path A and flux path B in parallel magnetic circuit.

Path A flux = total flux  x  Path B / (Path A + B)

So getting back to the "flux split" in your thoughts above, the total flux
in the output coil cores will be due to the load current being drawn and
the input flux.

The input flux is independently set by input current and ampere turns of
input coil.
The load flux or Lenz flux is dependent on the load current and at any load
value this input/output flux split will be a set ratio.

The Lenz flux almost always opposes the input flux which created it....so
it subtracts from the input flux, this makes the input coil core path look
less inductive, so it draws more current & requires an increase in drive
current to get back to original flux value.

However in the BITT the input flux is divided into two halves one clockwise
the other counter clockwise. In the side by side toroids.
This also splits the output Lenz fluxes A and B into two opposite phases,
one  rotating clockwise the other counterclockwise, so the output signals
are 180 degrees out of phase from each output coil.

Now by providing a low reluctance flux pathway from one output coil core A
to the other core B, a large proportion of the Lenz flux is routed to the
opposite (and out of phase) coil.
This Lenz flux from A side is now out 180 degrees phase with the Lenz field
on B side so the Lenz fields tend to subtract and cancel each other out.

180 degrees out of phase.... equates to opposite directions just as in our
battery subtractive currents example.
Because the low reluctance pathway between A & B is so low, a smaller
percentage ratio of the output Lenz flux finds its way back to the higher
reluctance input circuit.
