Claimed OU circuit of Rosemary Ainslie

[poynt99]

MileHigh,

From what we have learned so far any anti-clockwise current travel through the circuit is akin to a minuscule "cheater" type of spike as referenced above.

I think Rose may be referring to the reverse current back through the circuit if and when the body diode ever forward-conducts, which as shown in the sims with an 864uH inductance, can occur after the initial positive spike.

    Hello MileVeryHigh

I have no idea how to extract the quote with the limited editing tools of ou.com.  So.  Here's a hard copy.

"Without the fly-back diode you "smack" the MOSFET with the inductor's stored energy and the current flows through the full clockwise loop of the circuit.  With the fly-back dode, the inductor, the 10-ohm resistor, and the fly-back diode form a loop for the currrent to flow through, and the inductor's stored energy discharges through this loop." MH post1636

Now you have a situation where you classicists state that - notwithstanding an inherent repulsion due to their 'like charge' electrons now move together in lock step but in the same direction as the previous cycle.  And this, apparently is because they prefer to retain their directional path.    And all this notwithstanding the reversal of applied voltage which, in all other events determines the directional flow of current.  And in so doing it 'smacks' against the body diode of the mosfet and partially breaches its resistance? 

How complicated.  Why not just say - the 'stored' or 'recycled' voltage generates a current flow that moves through the loop that I described earlier?  And better still, why not just say that whatever is moving can't be electrons because they can't share a path.  And if it traces a path - anti-clockwise back through the battery then all the circuit's polarities allow for this path?  Surely that's simpler?

Poynt thanks for explaining my reference.  You're spot on.

TinselKoil 13c: Comparison of Duty Cycles in the Gate Modulation
http://www.youtube.com/watch?v=nqx0sHFSfl0&feature=channel_page
Continuous corona mode vs. staccato mode, with duty cycle variations in staccato mode.
The main oscillator, a LM494 pwm chip, should be set to a clean 50-50 duty cycle so that the mosfets switch cleanly. Minor adjustments can be made while scoping the final output, primary disconnected, to get a symmetrical set of zero-crossings to keep the mosfets happy. Some special effects might require slight tweaking, but watch the mosfet temps if you depart from a 50-50 symmetrical cycle for the main coil drive oscillations.
The variations in duty cycle here are taking place in the gate modulation. This is simply a transistor (2n7000, a tiny little mosfet, so cute) in series with the main pulse from the pwm chip, which is being driven by an external oscillator, coupled through a 1.0 mF tantalum cap. I usually have been using the little Elenco kit oscillator, but its duty cycle is fixed at 50 percent. In this video I hook up the Interstate F34 and use its pulse width function to explore the effects of duty cycle in the gate modulation.
This is also one place that a decent audio signal might be injected into the system.

TinselKoil 17c: A 40 Watt Incandescent Light Bulb With One Wire Connected to Coil
http://www.youtube.com/watch?v=7BMRJoqdy6E&feature=channel_page
Here I show an incandescent filament light bulb lighting to full brilliance on the output of the TKSSTC. The base of the bulb is connected with one wire to the top of the resonator and the other wire to a bit of aluminum foil suspended up in the air. It's amazing that the circuit, capacitatively coupled to the ground through the air and empty space, can carry that much power.
Even more amazing is that the coil could probably light up quite a few of these bulbs like this. I'll have to get some more and see.
================================
TK if you are reading my post I think it would be nice if he came back and started a new thread
on your fantastic work with the TinselKoil

Yes and I forgot about the diode arrangement possibly helping any oscillation mode also in the context of what Rosemary and Aaron are investigating.  Just being dopey.

Rosemary:

The Classicist view of current flow is that you can think of current flowing like water through pipes, it is a very accurate analogy as long as you are looking at the amount of flow at any point in the circuit.  The engineering-ese for that is "The sum of all currents entering any node is zero." So when the shunt resistor shows a negative voltage spike, all the current changes direction everywhere in lockstep.  The current can "overcome" voltages.  You can go up and down and back up and back down in voltage as you flow through a loop and the current all flows in lockstep.

And better still, why not just say that whatever is moving can't be electrons because they can't share a path.

I am not sure what you mean by "can't share a path."  As far as the way the current actually flows you might try a search "curvilinear squares."  I took a peek and I am not sure how friendly the links came up are.  Anyway, if you digest that, the real way that current flows in a wire is via "curvilinear cubes."  In a nutshell the current flows everywhere inside a wire and varies in current density.

It may sound complicated, but if you take some Spice...  You never know.

Aaron:

When I used a 6A100 blocking diode (very slow) and a 1n914 parallel diode, I was able to get a few degrees hotter at the inductive resistor while the current leaving the battery dropped 1.3 watts.

That showed me that bypassing the body diode with a better quality diode significantly increases efficiency.

ha ha I have good news for you here.  If we ignore EM emanation you are always 100% efficient.  Do anything you want with the circuit and you are 100% efficient!!!

  MileHigh - The only thing more complicated than the classical explanation of current flow is 'curvilinear cubes'.  And the only way that one could get the head around this concept is with the liberal application of some exotic medication or, alternatively, a facility to bend logic out of shape.  Actually there are other options but they all involve varying levels of induced, permanent, or temporary lunacy.  This, unfortunately is the weird and happy hunting ground of our quantum physicists who grapple with counter intuitive evidence and of our electrical engineers who - if they think at all -  - they assume logic where none exists.

If anyone out there is looking to find an explanation for current flow that does not require this creative. mental. acrobatic and wild distortion then how about this? Current comprises magnetic fields that simply twist and turn in relation to other fields.  And - if you put a particle inside that magnetic field then it is a magnetic dipole with perfect polar synchronicities.  That way we defy nothing - including Pauli's exclusion principle.  Electrons react but don't 'move home' so to speak.  Ion and molecules in the material behave as they should.   

No chocolote puddings - no strange distortions to cubic volumes - no 'holes' no 'directional' and whimsical preferences.  No toffee on train rails.     All just so much more simple.  Surely there comes a point where a simple proposal is preferable, provided always it conforms to the observed.  Magnetic dipoles as current flow actually provide this comfort.

By the way I want Dune spice.   Anything less than this and I'll pass.
