Note: This circuit appears to suffer from a problem where power is fed into the input pin leading to false conclusions about its performance.

I had some trouble getting YoElMiCrO's circuit to work for me as described. Initially I had thought I got it working, but it turns out I had made a mistake in my circuitry and ended up discovering a whole new oddity which may or may not get described in a future post.

So why didn't YoElMiCrO's circuit work for me when it works for Chris and possibly others? I have no idea, maybe my core is too picky or my windings too shabby, or whatever. However, I was not discouraged. I devised some changes which I think make it easier to work with. I've named it the Easy BCFT (Bucking Coils in a Forward Topology). For me these changes took a 99% efficient magnetic resonance setup (which is easy to get) and kicked up a notch.

The circuit has two enhancements, first it uses an efficient IXDF604PI gate driver (or you can just use two separate efficient gate drivers one inverting and one non-inverting) or any other method that achieves the same outcome. The second enhancement is that the single mosfet has been replaced with two IGBTs that do not have anti-parallel diodes. This did fix some of the issues I was having and I was able to get a little bit power out of it (signs of life), but reverting back to the 1 to 3 ratio with more turns did work better than the original ratio at lower turns for me. 

Easy BCFT - 02/05/19:

Duty cycle will likely be very low with on-times around 2-7uS and a wide range of frequencies that will result in successful operation. No special core gapping was needed.

Powered only by the signal generator charging the tiny capacitors in the gate driver to 5V 65k times per second the circuit self-charges a 22mF capacitor to 8.1V (YMMV) and powers a small load of 3 series ultrabright LEDs. Sorry no specifics, yes its AU (Edited to clarify this was a false conclusion), no further numbers will be forthcoming, this is eternal lantern level stuff for those who are looking for kW. If you are successful in replicating feel free to share your opinion or results if you wish. Proven enhancements always welcome here, or better yet, create a thread to show off your improvements. Enjoy.

@Zanzal - I am so very proud of your results!

Well done my friend!

We are showing the world how it is done! Fantastic! And you have shown how easy this can be! Ones thinking has to be right.

P.S: Apologies I did a small edit.

Well you should be proud Chris, it uses Magnetic Resonance and Asymmetric Reguaging, both of which you've been educating us on for some time. I think so far this is the most simple proof of concept for preventing conduction in the secondaries while the transformer is reguaging. Much thanks to YoElMiCrO for his very straightforward design.

If others results are as good as mine then no longer will lanterns need some finicky oscillator circuit, they could be powered by simple TLC555 using LEDs as a load regulator.

The tuning for this circuit is fairly easy, use a voltmeter on the capacitor to monitor the rise and fall of power on the capacitor. The capacitor should maintain a charge at some level if working and if it falls quickly then its not producing enough power and needs adjustment. If you have the ability to adjust the pulse width using time rather than % you may have quicker success. A decent "on time" will probably be proportional to the number of turns in the primary. The greater the turns the greater the on time. For mine this was 3uS at 12 turns and 7.5uS at 36 turns. Once a decent on time is found a wide range of frequencies should work at that on time.

One observation that may just be coincidental, is that I found that at the natural resonant frequency, the on time was roughly 50%. If you know how to quickly spot the natural resonance on an oscilloscope you may be able to quickly tune your device that way. Not sure if that was just my core or if that is something useful, more observations are needed.

@Zanzal,

Its all in the Timed Interactions of the Coils. Partnered Output Coils "Generate" Electrical Energy.

Well done my friend wink

You have that huge Wall of Water:

The Force is greater than the Initial Force. Conduction is hugely important, more so than we currently think.

Hey Zanzal,

When you have a minute, if you would like to add to, or point out any additions to my post here: How to build your own Above Unity Machine - Perhaps just a few bullet points if you have any?

I would like to encourage all to build and replicate this work, and also, remember, the basic outline, many ways work, this is just one excellent example! Do not limit yourself to any specific configuration!

I always encourage simplicity! 

Keep it cheap and simple, $20 and an hours work when one knows what is required.

Its how you think about it, when you have learnt enough, the rest is extremely simple! All of Andrey Melnichenko's early Circuits were doing the same thing! All of Akula's early Lantern Circuits were doing the same thing! All of Don Smiths Circuits were doing the same thing, All of may others Machines are doing the same thing.

We are following in the footsteps of the greats, before us. We should thank them for the contributions they gave! However, it is you making a Global change! Be proud, you are Part of something Better!

My Friends,

I want to point out, we have seen this before, here: "Partnered Output Coils - Free Energy", and also here, but the Circuit Zanzal has shared does have two Current Directions and these directions are perhaps not realised by some.

 

D3, the internal Mosfett, or internal IGBT, Diode, most have, but some don't, so, we must consider the switch Q2, ON in one direction all the time. I posted some info about this before, mentioned above:

 

 

 

 

So, I urge, don't forget about the Conduction Paths, Arrows are running in two different directions, this was pointed out by YoElMiCrO also.

Perfect zanzal.
I'm glad it works.
If the time of Ton is linked to the number of turns.
The relation is Ton = NpBmAe / Vp.
The load should be in constant tension, as the fordward voltage of a led, which is kept constant for a certain variation of current.

It is important to note that it is only possible to extract energy during the fordward cycle, also remember that Q = CV = it.
I already have the 3W Led in my hands, but it's late, tomorrow I'll try to test the circuit I designed with the controller.

Thank you.

Hey friends,

I think there may be a problem with this circuit. The signal generator appears to be feeding power in through the input pin. This was not expected, and is disappointing. Feels like another huge fail on my part.

Just thought I should give you all a heads up. Looks like I am going to have to eliminate the signal generator from all future tests. Confirmation bias strikes again. I'll keep working on it....

Chris posted this 06 February 2019

@All,

Yes, this is a consideration! Leakage is mostly extremely small, in the nanoamps and normally indicated on the datasheet somewhere:

 

 

This is a matter I also experienced some years back replicating a Cap Coil setup that seemed to be running by itself at the resonance frequency, not powering any load.

I must urge, don't be discouraged, this small problem is not enough to light 3 LED's and run the System all at the same time. So a small issue like this most definitely is not where all Above Unity Machines get their excess power from, obviously!

   Chris

 

P.S: Zanzal's variant of YoElMiCrO's circuit has huge potential. After all, YoElMiCrO's circuit has the exact same principles as Akula's Lantern circuit!

Hey Zanzal,

considering the issue with the signal generator in my opinion there is no leakage to be considered regarding the IGBTs (or MOSFETs) as the driver is powered by the circuit rail in your schematic. If there is  leakage it could be only thru the driver IC, and only if the voltage of the SG output is exceeding the railvoltage. you could try to lower the output voltage of the SG or use the TTL output.

I hope this helps some.

Vidura/Chris, I agree, the circuit is still promising and leakage current through the gate is an insignificant consideration for what we do. Which is why I did not question the results.

I verified my concerns using a tester that there is a diode in the gate driver between in and Vcc. Voltage drop was 773mV. Also, part of what I noticed last night that made me realize there was an issue was that I noticed my input voltage was set to 10V on my signal generator, I had recalled setting it to 5V, but I must have changed it at some point. Setting it back to 5V caused a dramatic loss of power.

Inspite of this mistake the circuit itself has potential because the switching and the efficiency of the gate driver is good. I just have to make sure that future tests use self-contained switching. As long as the signal voltage never exceeds Vcc then a signal generator can be used, but I don't like repeating the same mistakes over and over again, so my next priority is an ultra low power square wave generator.

Hey Zanzal

Your choice of current driver IXDF604PI is good. As you already know you can put in parallel as many as you wish same type drivers. On that way you will boost current source/sink capabilities over the single driver and also drastically drastically lower input time constant of MOSFET/IGBT transistor or simply, shorten gate/source(emitter) parasitic capacitor charge/discharge cycle.

I like your IGBT option because he has not parasitic intrinsic body diode between drain/source(emitter).

Also any good newest generation Silicon Carbide Power Mosfets could be used here, simply adding pair of antiparallel very fast recovery high voltage high current diodes to transistor's output to cut-off intrinsic diode.

ps: Maybe is time to put some isolation transformer between your function generator and test circuit. You can make one easy with small toroid ferrite ring and pair of primary/secondary winding in 1:1 ratio. Diametr of wire 0.3-0.5 mm.Number of windings 30-50 each coil. Also is useful to make small air-gap 0.5mm or smaller in the ferrite ring to avoid core saturation. Wind two coils in the same time (in parallel) and mark start and end of windings. This type of isolation transformer is preferable for HV test setups.

Hello Zanzal


Yes I believe like you that your circuit has a lot of potential and for that,

if you want I can suggest you a very simple circuit which works even with a very low output TTl

and which protects us from the short circuit which could damage the DUT

This circuit I use it with almost all the experiments that I do, it uses an optocoupler and a mosfet.

Resistor R2 provides current limiting to prevent Q1’s gate-source capacitance

damaging the driver’s output at turn-on.

It may also be necessary to prevent the MOSFET from oscillating.

A value of a few hundred ohms is usually suitable.

This little circuit I avoided many bad surprises as you have recently lived

Chris posted this 07 February 2019

Hey Jagau,

Agreed. Many ways exist to isolate this problem. Your method is a good example. Thanks for sharing!

 

On another note - What causes Transients?

 

Say one was given the task of creating a Transient, it had to be a particular Voltage Amplitude. How would one go about this?

Its easy right? Zanzal's Circuit will Cause a Transient! But the Circuit must be right, one Coil must conduct, the Switch must then Bang, hit the Magnetic Field hard, this very fast change in Magnetic Fields will cause a large Transient. Why do we want to look at this? Because: I = V / R

Current increases with Voltage, and the Resistance, or Impedance, can only drop. Reduced Impedance Effect.

Don't give up! This circuit has a lot of potential, its been used before! Graham Gunderson's Circuit is very similar! I urge all here, this circuit will work, but again, follow my basic outline in my thread: How to build your own Above Unity Machine

Hi all

As I already said in one of my threads
the effect is greater when the primary coils are asymmetric with different inductances (lengths of coils)

Don Smith has already explained that this creates a slight delay on one side of all the coils

and he was right, I got better effects that way

@All - I urge all go back and revisit the facts.

This method does work! The Coils slap together as hard as the can, Magnetic Fields Oppose, Currents Oppose! When this happens, the Voltage in the Terminals Increases, because of the very fast Time Rate of Change of the Magnetic Fields.

Work up around the Knee of the Saturation Curve, this can be seen on the Scope as the Peaking on the Current Waveform:

 

Seen in Red, the Current will start peaking, so at this stage turn down the Voltage just a little until the wave goes back to Sinusoidal.

High Frequency I have had not much luck, most all of my machines are low frequency and more turns. As an example of this:

 

 

 

 

Akula also used low Frequency on most of his smaller units: 260 Hz, remember this is Andrey Melnichenko's machine, not Akula's. He only replicated the machine.

If you look at the Wave form, the direction of the Diodes and the discharging mosfet, triggered by the Voltage on the Cap/Coil via the CD4069 Hex Inverter, it is indicated the Current is in reverse.

DONT give Up! Remember: Equal and Opposite! You guys are practically there! You have all the pieces of the puzzle! Look at all the spikes, Look at the Duty Cycle Pulses, look where they are and what they are doing... The Waves Slap together and a Wall of Force Grows, like this:

Ref: https://www.youtube.com /watch?v=EUXOZAinUPk

 

This is the Regauging Part, then the Wall has to dissipate!

 

 

The resulting force is much Larger than the original Wave, it can be more than twice as high as is predicted in Science!

Ref: https://www.youtube.com /watch?v=MFmQhx5Wq3E

 

Quite some time ago I posted this to try and help:

 

This we have already seen! Electromagnetic Waves are exactly the same, we can manipulate them exactly the same way!

I didn't have much luck with AU yet, but I decided to take a different approach. Using this circuit to study what happens when the core demagnetizes.

The method is simple, using my original circuit with only two coils and a 1ohm resistor between the secondary and Q2, I make a floating measurement over the 1 ohm resistor using a handheld oscilloscope. By swapping coils I can study how the current flow changes.

The results are.. peculiar, somewhat unexpected, and even inexplicable at times. As an example, the current configuration under test at 300Hz and 4.7% duty cycle would have me believe that the peak discharge current exceeds 2amp and flows in the wrong direction inspite of the diode D1 which should prevent such a thing. I'm not really sure what to make of it.

The great Nikola Tesla:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago go by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
