Isolating flyback pulse

What is a good simple way to isolate the flyback pulse in order to derive only the energy from this collapsing field and none from the energizing?
 

 Something the opposite of a freewheeling diode that would not short out the supply pulse.

Hi Kone,

 "IIF you want to capture it, and have it do work, t MUST be a two-stage process, with the steering diode (or FWBR in the "ultimate" case as I described previous post) first filling the capacitor in the first stage, and with the capacitor all by itself and NO LOAD on capacitor.
 2nd stage is the capactitor is disconnected from the pulsed DC coil circuit, and the capacitor all by itself, all alone, discharges to load, this being the 2nd stage..."
But all the energy is still supplied by the power source at the input. This happens even it a long pause is made like putting the energy into a battery and waiting for some minutes before discharging the battery totally isolated form the charging circuit.

There is also the Ćuk converter:

Slobodan M. Ćuk's latest converter:

And there are also switched capacitor converters (charge pumps):

For free energy some other source of energy is needed than the one supplying the energy to the input stage. Something like Pierre Cotnoir is doing or Tariel Kapanadze is doing by mixing different fields into a single field before harvesting the difference in energy levels would be better. A parametric change of the inductance or the capacitance could be another way to achieve the goal if it is getting free energy.

 Hi Ole and Mick
 you should not have a load across the capacitor!!!
 I looked at the Wikipedia link, that rectangular box to the right side in those circuits represents a load...(if voltage meter that is OK then)
 

 The load will not only cause draw to go up in consequence and also it will prevent the capacitor from filling up as it should!
 

 Depends on what you want to do. suppress and extinquish the flyback energy or capture it into caps then release caps to load to do some work and create some power and watts...

 IF you want to suppress and extinquish and "make safe" your circuit that is one thing, but if you want to CAPTURE all the flyback energy and put it to work without affecting draw at al, in fact making it less draw, l that is much better way to go.

Hi Mick
Fill capacitors-only to catch everything 
Discharge capacitors.by themselves then fill again after discharge.
Filling capacitors will not short out anything furing discharging as long as caps are isolated by themselves during discharge (and fillimg)
AKA two stage output circuit
Fill caps with dc sides of fwbr A and fwbr B
Fwbr A to cap A and fwbr B to cap B
Switch pulsed dc coil with switch A at hi side of coil
Simultaneous switch with a switch B at low side of coil
AC legs.of fwbr A across hi switch A
AC  legs of fwbr B across lo switch B
Fwbrs made of hyper fast HV diodes
So dc of fwbrs into the respective caps
Doing  like this will catch "both sides" of inductor.
Walter Rosenthal sent me circuit in snail.mail to do it like this he also called me on phone about this too long time ago....also Bill Muller told me this is how they do it too with their motor coils ..in Bill Muller's case also he does it like this when switching on off inducef-by-sweeping rotor  magnet generator coils into caps during peak periods of sinewave ( such as the 1/4 portipn of wave similar to diode plug)

Hi Mick
You need the energizing of course to get the collapsing field to happen at switch opening  but at least there will be no reflection or extra draw to the primary pulse, in fact lower draw....
Experiment with collector cap sizes because  if too small of UF,  you will not catch everything and if too big the cap will be seen as resistive load instead of "resonant collection chambers"...
Once caps fill, they will stop collecting collapsing field energy so they must periodically discharge...expermemt with when and how much of discharge.

Hi Mick,

"What is a good simple way to isolate the flyback pulse in order to derive only the energy from this collapsing field and none from the energizing?"
A simple diode as used in the flyback converter (or inverter) is enough.


The image is from here: https://wiki2.org/en/Flyback_converter https://wiki2.org/en/Flyback_converter.
The circuit above is also galvanic isolated by using a transformer between the input and output sides.

Here are some other possibilities:

Source: https://wiki2.org/en/Buck-boost_converter https://wiki2.org/en/Buck-boost_converter

The buck converter lets power through to the output during part of the cycle. The flyback pulse is decoupled from the input though.

Kone,

Yes the problem is functioning without loading.

I want to use it in another coil while it is still conjugate, one stored
in a cap I think it becomes normal E field.  Some of these diodes do not
switch without a load so are not useful in one wire experiments.  What
diodes have you found to be good ones at capturing?

What differences have you found with a full wave implementation vs half
wave?

Only the Schottky diodes were useful in capturing the PM RF energy into
the cap in the experiment I show.  High voltage RF diodes are likely the
best bet.

Hi Ole
 regardless of in itself is overunity or free energy or not, the flyback is lots of energy, theoretically the same amount of energy as what goes into the coil, but saved up and stored in coil, and released all at once in a high voltage spike event of very very fast release and tension....my theory is faster than speed of light but that is my theory is all.
 To disregard this energy and snuff it out with a resistor is just not good idea if you are trying to make something run overunity or be free energy.....
 Coherence would come about with the flyback cohering with the actual inherent back emf forces....this can be done (I think) by putting a delay in time when the flyback/steering diodes connect....about 5 degrees delay like an echo...this lets the backemf forces get bottled up within coil and released in same direction as the flyback, both guided insame direction by the steering diodes....when these combine it is now not a spike going backwards, it is a very very strong force going backwards that can kill since combination of current and voltage...

Hi Kone,

The signal speed is given as the reciprocal of the square root of the product of the permittivity multiplied by the permeability. Unless the product of those two physical property constants become less the signal speed won't go up. It would be hard to find something where the constants become less than what they are for vacuum or air. W.B. Smith claimed that his tensor beam was instantly from one end to the other or at least too fast to being able to measure any period of delay in the propagation. Smith made a field that had the tempic field along the beam.

If having enough OU there should be energy for driving some load like it is done by solar panels heat pumps wind turbines etc. Why else spend time and money on such a project?

"Coherence would come about with the flyback cohering with the actual inherent back emf forces..."
Back EMF or counter EMF https://wiki2.org/en/Counter-electromotive_force is what opposes or is induced by the rate of change in the magnetic field of the coil. The flyback pulse is the voltage induced when releasing (or demagnetizing or 'discharging') the magnetic field of the coil. This is also given as the rate of change in the magnetic field during that demagnetization. For making a coherent field the way W.B. Smith talks about it has to be made from two separate fields that merges into a new field that then becomes coherent. That is the two original fields don't ride through each other like in simple superposition or like two ocean waves crossing each other. The waves have to keep on riding on top of each other in phase and thus become one single wave.

Look at what Pierre Cotnoir did! I have built a hex MOSFET bridge. This isn't enough or at least I haven't got any OU yet. I'm now building one more hex bridge for having 12 bridge outputs. This should be adequate for overlapping fields through several poles. This is built in small scale as the principles are the same independent of size. This makes it cheaper to scrap if it doesn't work. This has taken quite some time since February or Marts. Just stay away from relays working at their max frequency as they will burn out fast like Pierre experienced. He ought to have read the datasheet.

Ole

 Do not have a resistor across the cap filling up!!
 This will also work to load the whole thing down at the input very bad
 besides making it so cap will just not fill or capture the flyback energy as it should.
 Discharge cap into a coil of very high impedance maybe good idea for your experiments...
 With FWBR, there will b e only one diode of the bunch of four that takes the brunt of it all...really you only need one steering diode per switch, but I think ringing is going on and you catch al little more with FWBRs...also if you have rotor of magnets sweeping past coils, there will be more than just the flyback to catch with FWBR configuration...
 Kone

Hi Ole
I don't think flyback energy can be measured properly not even with the fastest scope available
Not only are voltages ghosting on scope but so is the time too.
But one way to measure it is to pop it into suitable lead acid batteries and charge up the batteries with those fly back spikes only.
Then run loads with the charged batteries and run them down until they need to be charged up again.
Do about 20 cycles and keep neasurements how many watts are consumed from the batteries running loads compared to how many watts it took to charge them.  With a good charging system like the Bedini wheel you will see overunity.
More believable is simply run let's say electric  bicycle motor with a battery A and have flyback energy from dc bike motor charge battery B 
And when battery A runs down, have bike motor to now run on battery B...it won't be overunity since bike motor pulls in so much amps, but you have extended the range quite a bit. Now flyback is doing useful work at least, not just snuffed out to protect  mosfet gates.
Those flyback spikes will induce their energy into pickup winds, that is, additional winds around or behind or next to, or within, (bifilars) the primary winding that is emergized...and these pickup winds sharing common core.
So combine this pickup-energy induced, with the flyback energy and there is some coherence going on. Just get it going same direction with diodes then deposit into capacitors.
The formulas you give I have doubts about since these will be based on accepted power formulas and for power measurement to be acceptable there must be direct resistive load or there is no power.measured according to what is accepted.
But that is what always kills everything, the direvt rezistive load always "required"
So fill capacitors only and discharge capacitors only in two stage process so only the capacitive discharge is power and watts.
Permeability of cores and resistance of copper.or. steel or aluminum in wires is all about their resistances or acceptance  to either magnetic forces or electrical forces and so you cannot have electrical flow without magnetic flow or vice versa so if formulas formulated always on direct resistive loading,  either magnetic or electrical, then formulas all flawed since they are concerned with only one approach into "what is" power.
Consider also "what if" the actual inherent backemf forces in magnetic or electrical field can be "seperated" or tricked.into joining forces going same direction as some other electrical force going that same direction as well, instead of always opposing the primary flow? Could this be.measured if this was to happen?  Perhaps the good results could.be measured or destructive...
One more thing is I think looking at flyback energy as only voltage is big mistake since introduce just the two components offices and caps and it can transform to huge amperage.
Kone

Hi Kone,

An easy way to measure the energy of a flyback pulse is to dump the energy into a capacitor through a diode. When the capacitance of the capacitor is known and the voltage across it it is very easy to calculate the energy it stores. If no resistance is involved the energy is pure reactive and can be taken out of the capacitor again. If there is resistance like using copper wires some of the energy will be dissipated as heat (active power) and thus won't be reactive.

If doubting the formulas then try the experiment with a digital storage oscilloscope having math capabilities and hooked up as a power meter. If the formulas don't fit we will have to find the correct formula to substitute the wrong one. Of course the measuring equipment will have to be calibrated to fit the formulas which can be done against national or international standards. Cheaper instruments may be accurate to perhaps 5 percent. Read the manual.

A free energy device capable of running itself and perhaps being able to deliver some active power like driving a light emitting diode can of course be measured. A small load like a LED can be easy measured with the proper equipment. If only having reactive power sloshing back and forth inside a device what is it good for?! Even a solar cell can deliver active power to an external load as long as it receives light of the proper wavelength.

When saying that the energy can't be measured then if an effect can be observed this indicates that some measurement is possible. Galileo formulated that to be called scientific an effect had to be measured. Thus lots of measurement equipment was invented just for that purpose. If the effect can't be measured with existing instruments then make some instrument to measure it. W.B. Smith made his binding force meter http://www.treurniet.ca/Smith/BindingForce.htm even though he didn't find a way to calibrate the scale against some other known units. Here is an effect open for inventors to perfect this binding force meter. This could be useful for construction calculations to know the strength needed. The binding force could be plotted like the temperature to study its fluctuations or to see when atomic explosions have weakened the binding field to be able to warn against earth quakes.

"One more thing is I think looking at flyback energy as only voltage is big mistake since introduce just the two components offices and caps and it can transform to huge amperage."
For electrical work (changing energy of one kind into another kind) current (amp) tension (voltage) and time (second) is necessary. For power the time isn't necessary as power is the rate of transferring the energy at any given instant in time. So you're very correct that voltage isn't energy. If knowing the other parameters like the capacitance of the capacitor the energy of a given voltage can be calculated as well as the charge being stored. Or by transferring the energy to a load it could be measured which can be compared to the calculation to see if the formula is correct. This is what is being done in physics classes in schools.

DougAs you know, I did just what you are suggesting.I collected the arcs and sparks from a dc permanent magnet motor by placing the a.c. ends down across between the two brush wires, then powered a second motor with that harvested signal.Two things to note.The signal was a slightly higher  voltage than thethe 1st motor. The first motor ran very cool.I intend to pursue this range of experimenting further.Cheers WarrenSent from Yahoo Mail on Android

Hi Warren
Your daisy chain of PM brushed DC motors very successful experiments  with AC side of FWBR across motor A brushes and DC side of FWBR feeding next motor  B at its brushes  and so on down a line of DC brushed motors U think could be me more spectacular with not standard FWBRs but instead 4 of the  the new 50A 400V hyper fast diodes they sell now, which is going to leave nothing behind in the transfer from one to other.
Perhaps the inherent backemf forces locked into magnetic field by nature are allowed to manifest and transfer because of the FWBR instead of the usual single steering diode most people will do,since it works bringing out the flyback spikes already and is common way to do it....maybe something more happens of great significance with FWBRs..
Also more advanced is have double commutators on motor A and commutators #1 works normally bit commutaor #2 becomes a switch to connect motor A to motor B  but commutators #2 is used as 2nd switch to delay about 5 degrees ( like echo) connection of one of the AC legs of FWBR and then adjust this timing to findb sweet spot.
Motor A should drop down in amp draw and motor B will have even more power and speed.

Hi Warren
 The AC sice of FWBR, I don't think it matters which leg goes where, as there are two opposite facing diodes at each terminal of the AC side but I see what you mean, once the daisy chain starts and you go to the third motor, now which AC leg is on the positive of the 2nd motor might make a difference but I don't think so but keep track which is which just in case it really does matter a lot.
 

 The :ultra fast: ones I use a lot since I bought about 50 of these a few years ago is:
 HFA20PB50.
 

 The newer ones even faster more robust and described as "hyper fast" are these ones:
 RHRG5060
 Here is link to these on ebay for 3 bucks each from 
USA:
 https://www.ebay.com/itm/RHRG5060-DIODE-NEW/173382835840?hash=item285e6c1e80:g:v-IAAOSwBiBavAHj https://www.ebay.com/itm/RHRG5060-DIODE-NEW/173382835840?hash=item285e6c1e80:g:v-IAAOSwBiBavAHj
 Look around on web for good deals ...

 I am reluctant to name the cause of this energy, until we fully understand it.
 However, it is most certainly there, in addition to the energy you provide with your battery, or power source.
 I love the utter simplicity of the set up, and am planning a giant group hug with all my DC motors, assembled in one place, just to see how crazy impressive this energy can become.
 Thank you for the tip regarding those ultra fast diodes.
 It would be nice to mount them on heavy duty terminal strips.
 I would like two rows of the terminal strips spaced exactly a comfortable distance apart to place the diodes across like rungs in a ladder.
 It is a huge advantage to see each individual diode, and be able to run the laser thermometer over them checking how they are doing.
 Many components have quality control issues right out of the bag.
 It is a shame to get bad results just because of a dud diodes, and making false assumptions about poor performance.
 Where do you buy your diodes?
