Some thoughts on how the TPU might work.

wattsup,

You should actually get some induction from coil to coil with a bifilar winding. It's simply just a loosely-coupled air-core transformer.

Adding a flux-concentrating core allows better coupling and hence better induction from one to the other.

The point I've been trying to make all along here is the 90? orientation of coil1 with respect to coil2 is what nullifies the induction effect.

Hi all:
   Anyone herer take notice that his last time on was November 29. He made "2" posts on the 27th and then was gone. No more to be seen. Nice way to start a thread out.

Hi folks!

I just got back from a whirlwind tour of Europe. All work, no play ââ,¬â€œ still suffering jet-lag but I see terms like ââ,¬â,,¢90 degrees nullifies couplingââ,¬â,,¢, ââ,¬Ëœbench experienceââ,¬â,,¢, and thoughts of no inductive coupling between perpendicular coils.

I canââ,¬â,,¢t be quiet here because I just had these arguments with Dutch, French and German EEââ,¬â,,¢s. While I cannot go into details on the circuits I had to fix because of the ââ,¬Ëœupgradeââ,¬â,,¢ efforts of these people I will tell you this:

90 degree coil orientation minimizes conventional inductive coupling. It does not nullify it. Typical reduction is 30 dB, in ââ,¬Ëœfar-fieldââ,¬â,,¢ RF terms. Of course, most do not think in ââ,¬Ëœnear-fieldââ,¬â,,¢ terms. Coupling adjustment can be obtained by varying the spacing between the coils OR the orientation OR the relative position. Ever hear of ââ,¬Ëœseries and parallel aiding or opposingââ,¬â,,¢ or just aiding and opposing coupling? How about the fact that in near-field the magnetic component is dominant NOT the electric component? Old radios made in the early part of the 20th century that used variable orientation between coils to control resonance for tuning? No? I suppose not.

Conventional thought on coupling is to induce a like signal in the secondary. This is good when the coupled coils are parallel. Unconventional coupling is to induce a secondary signal unlike the primary. This secondary signal can only be the resonant frequency (and harmonics) of the secondary coil ââ,¬â€œ regardless of the primary frequency. This is done with perpendicular coupling.
Granted, the result is weak, especially when the designer continues to limit their thoughts by the book. There is nothing wrong or new about the physics. The book is only a starting point. It is NOT the answer.

The way to enhance the power from the secondary I see as the following:

The higher the primary signal voltage (not Amps) the stronger the induced ââ,¬Ëœringingââ,¬â,,¢ of the secondary.
If you control the primary pulse width to the point that the primary signal fall aids the ringing of the secondary instead of dampens it you enhance the ringing.
If the secondary is resonate at some harmonic of the primary the energy output of the secondary can be improved without increasing the power drawn through the primary.

It is no different than striking a tuning fork or ringing a bell. No matter what frequency you hit them they will vibrate at their resonance and over/undertones.

If you donââ,¬â,,¢t control the pulse width to aid the ringing it is the same as pushing a child in a swing and not timing your pushes to aid the swinging.

Yes, there is such a thing as perpendicular induction. Maybe there is some secret name for it other than induction. I donââ,¬â,,¢t know. Keep denying it and some poor slob will be forced to fly during holidays and fix the problem.

Every time I see implied ââ,¬ËœLaws of Physicsââ,¬â,,¢ it pisses me off. There are no laws ââ,¬â€œ only our interpretations of what was written and the interpretations of the observer. Too many seem to think the observations made decades ago just canââ,¬â,,¢t be incorrect or incomplete OR EVEN WORSE ââ,¬â€œ applies to all variations of phenomena. To that I say ââ,¬â€œ stay where you are comfortable ââ,¬â€œ enjoy the show. Iââ,¬â,,¢ll be glad to set my bench afire just to learn more. It is already charred.

Bench experience? Yea, right. Have you ever run into an odd signal in a line of amp stages that just didnââ,¬â,,¢t fit the band intended to be amplified? Usually near the BFO or mixer stage? Well guess what. The coils in these ââ,¬Ëœseparate stagesââ,¬â,,¢ are usually oriented for ââ,¬Ëœnullifying the couplingââ,¬â,,¢ between them. The signal is coming from somewhere. It ainââ,¬â,,¢t just ââ,¬Ëœnoiseââ,¬â,,¢.

When you strike a bell with a hammer the sound of the bell is so much louder and longer than the hammer strike. Also it isnââ,¬â,,¢t transverse.

Simple solution to any argument: Prove or disprove on your own bench. Make sure you look close. Do this EVEN if the book says it is true or false. If you did it before under tutelage, try it again and look closer.

I donââ,¬â,,¢t know the secrets to this thing but Iââ,¬â,,¢m having a blast learning more. Iââ,¬â,,¢m over half/century for some time now and the learning is even more fun.

I canââ,¬â,,¢t wait to see what the South Americans think of some old lunatic running around flushing toilets and recording which direction the water twirls! Only now I also have my little piece of resin to twirl on the desk. So far everywhere in the Northern hemisphere it prefers to go counter-clockwise. This is not possible according to ââ,¬ËœThe BOOKââ,¬â,,¢.

While I have great respect for work done by many hereââ,¬Â¦.

BOOK thumpers can eat my shorts 

I wish the rest the best of enjoyment of whatever holiday is current or coming for them! After some eggnog Iââ,¬â,,¢ll be exploding some caps for goof measure.

BEP, that was a great post and it couldn't be any better said. The things you are finding out have already been found out but they have been hid from us. We are just now starting to collect all these things that have been hid from us and more up us are starting to use our common sense to understand things a bit better.

It is obvious that electricity is nothing more then a collection of vibrations created from frequencies which were created by a resistance between two objects. It could be wind, it could be other frequencies from the opposite direction, it could be from explosions from the sun, or it could come from a combination of all. Regardless where they are from, they are still frequencies and frequencies are what we need to collect and or create to produce electricity for us to utilize as a main power source.

BEP,

When I later saw you were online, I KNEW you would be posting something here in an attempt to derail everything I've said here. I expected nothing less from you.

You can jabber whatever you want regarding your experience and my experience, and how much "outside the book" you know and have learned (or at least think you have), but the bottom line is as I already stated it twice now, and am getting tired of it, is magnetic coupling does not occur between two orthogonal coils...period! If you want to get nitpicky with perfection, go right ahead and fill your boots.....I don't think dfro was going to that degree, and neither was I.In general this is the case.There is a reason inductive components are placed orthogonal to each other when interference needs to be minimized.

Good grief, folks love to nitpick! Nullify, minimize....take a pill my friend. The world isn't going to end because these two terms were used to say essentially the same thing.

I have done your experiment with orthogonal coils.I have seen the resulting output on the other coil.I know about the timing and resonance.

Let go of the "you're stuck with your head in the books" idea about me. If it was so, I would not be here right? Perhaps you and others have completely missed the point (and also already destroyed it by now) that I was trying to coax an answer from the author of this thread. Trying not only to get him to think about it, but to respond as well. But as usual, these threads are hijacked and derailed by jack-asses that have nothing better to do than barge in and jump all over folks when they see an opportunity to flex their so-called esoteric brain tissue to prove they can think outside the box.

Well, you folks enjoy and revel in your all-knowingness. Meanwhile, I and a few other folks will just stand by and let y'all continue going in circles, as it seems you so much relish doing.

Merry xmas
