Lenzless transformer
« on: December 18, 2013, 11:39:45 AM »



I did some experiments using ferrite E-I core and I could take power from it without any visible effect at the source. I could not measure it exactly as I used two similar halogens. I got one in the primary side and similar bulb as a load.


E-I has three legs, so I wound one layer of 0.31 mm enamelled wire on each leg and used same number of turns. Winding direction most likely does not matter but I used CW-CW-CCW, so outer legs were opposing. These I then connected together in parallel so that polarities match and it was connected to load.
Primary was then wound all over the core so that is covered all three inner coils. Idea is that those inner coils form magnetic loop while the outer driving coil does not form a loop.


Primary magnetizes the core and current begins to flow in inner coils. As there are loops all inner coils amplify each other. Now the flux goes through the primary once from the left side and once from the right side, thus total effect is zero on the primary.


There must be power circulating in the primary so parallel capacitor should be placed in the primary to get reactive power circulating there. I was unable to make resonant circuit so this is were you the experimenter come in. See if this can be tuned so that only reactive power is used.

I used audio amplifier so I could get upto 20 kHz AC input. My core was such that I begin to see power out only after 15 kHz. If any of the coils were not connected there was not enough power to light the output bulb.

Other options
Put resonant capacitors in the smaller inner coils, so there will be two identical tank circuits having C and L. Output is then taken only from the middle leg and put resonant series capacitor there. If the center leg is larger then you need to adjust difference in L using lower valued C. Idea is to get resonant rise in the capacitors so that output power is increased.


Having succeeded in the above, raise the voltage in the input side to get more reactive power circulating.


Good luck experimenting.

Below a picture of the resonant version. One option is also to connect outputs so that all of them go to load via series capacitor.

Hello and thanks for starting string.


i would like to see your actual setup.
i need to know the dimension of your EI core also number of your winding,
as i am going to replicate your setup, so we could share our calculations.

So far, I manage to get and ferrite E-E core for my experiment.

Thanks and regards,
D.J

You core looks to be of same size as mine. I got mine from a broken printer, had to do some grinding because it had airgap. I don't have camera at the moment.


I was able to put about 50 turns in each leg. Turn count does not matter, it was just my initial test. When output coils are placed in parallel it is important to have same amount of turns in each coil. In primary I also used about 50 turns so I could get 1:1 action.


I am thinking to add more turns in the center, output power should increase. First I double it and use the same amount of turns in primary coil to see what is the effect. If it works better then I could try add as much turns as possible and see if I can get light in a 220 volt light bulb.


I got visible power only beyond 15 kHz so this means input power depends on frequency so it is a good start. I think it depends on voltage in the primary also, maybe we can find this out.


I hope you have scope so we could see pictures.


Thanks for joining in, this should be interesting.

Excellent stuff !


Much more professional looking than mine. I needed more room for inner coils so I didn't use coil formers.  Winding them was a major pain, couple of hours at least.

Hello Jack.
No, gap in core. All three secondary wires are of same direction same size and turns.
I also find that the middle coil is of more inductance than the side coils.

I think better is to avoid to make them in parallel and use separate capacitors for each,
as per your second drawing.

I am going to try this circuit for my primary.
As it state that it is self resonating(Auto Resonance).
So in this case L1 will be our Primary or driving coil. And we have to wind some extra turns for feed back
coil(L2) on L1. And sure we have to replace a capacitor for the HHO Cell.


What is your circuit for driving your primary?


Regs, DJ

I am using audio amplifier and Goldwave audio editor (free software) on my PC for creating waveforms. Headphone output from the PC is connected to audio amplifier and its loudspeaker output I connect to my test trafo.
Goldwave can create any kind of waveform using its expression evaluator tool, frequency sweeps using sine or pulse input for example.


You got scope ? Can you verify the effect that output does not affect input ?


Once that effect achieved all we need is to create resonant tank circuit in the primary and drive it using a spark. When spark hits at the correct moment oscillations in the primary coil increase, provided that there is new hit before oscillations have stopped. I think bifilar coil as the drive would work best, no capacitor needed, coil is the capacitor. Bifilar is good also because it has more self capacitance so it will ring longer and at higher frequency. As the oscillations increase without limit there needs to safety valve. For example use gas discharge tube which has 220 voltage in the drive side and then GDT with e.g. 600 voltage as the safety valve in the bifilar coil side. This GDT then connected to ground, or a metal object.


I forgot to test the effect of putting output coils in series. I did three experiments:


1. Outer coils shorted with itself, two shorted coils and output from the middle. When I connected load bulb, light intensity on primary side briefly increased and then returned to almost the same level it was.


2. Inner coil was shorted and outer coils connected in parallel to load. When I connected load bulb, light intensity on primary side decreased, barely noticed it.


3. All coils connected to load in parallel. When load bulb was connected, absolutely no visible effect on primary side.


This is why I think connecting load coils parallel works best, but this is just my testing. Maybe things work different for you. It is worth checking out different variations.


This circuit you posted is worth testing, but I think it is also good the get a feel of your initial condition.
What kind of frequency there needs to be at input before enough power is seen at output ?
Is there some limiter frequency that once it is reached there is no longer power at the output ?
Now that there is feedback coil in the primary in your drive it might ruin resonance condition, at least it differs from mine. Maybe better to take feedback by putting fourth coil in the output side ?


Anyway, possibly interesting times ahead.

Yes i have scope and function generator.
ok. i am going to use this simple circuit to the tests.
you can also use this with your pc function generator.


please feel free to asked me if you want any test. i will do for you.

I don't have any transistors so my ability to test is limited to PC. Also as I don't have anything to view output except halogen. So here is what could be tested:


TEST1:
Connect all outputs parallel and directly to load, no capacitors.
Generate sinewave input. Monitor input and output when there is some load. Switch load on/off.
  Does load affect anyway to input ?
  How much current goes in output when load is on ?
  Voltage seen at the output when there is no load should be low. When load is connected also voltage rises because those three coils all feed each other. Can this be verified ?
 
Do frequency sweep, start from kHz range and increase it upto the limit of the core.
  Does increase in frequency also increase power at the output ?
  Is there a sweet spot ?


Frequency sweep using pulsed input. Change duty cycle 50% on 50% off, 25% on 75 % off, 10% on 90 % off.
  Should there be a diode on the input side to enable better oscillation in the primary ? I think it would be useful. Now the pulse acts like a spark gap, it hits the coil and it begins to oscillate. Using diode should make the oscillation to happen in the coil only.
  Is there anything different at the output ?
  Is there a sweet spot ?
  Maybe there needs to be a safety spark gap at the input. What if there is a sweet spot and voltage rises in the primary too high level damaging something ?


TEST2:
If above test was positive then lets proceed to next step. 
If you have capacitors those could be tested. But most likely resonant frequency will be low. To over come this, all coils should be done bifilar and we use coils as capacitors: Two wires side by side and one wire connected from the end back to start. Use same amount of turns so results can be compared with test 1.


If you find anything interesting then some scope pictures for all to see would be nice to have.


btw, I will be off line during weekend.


EDIT:
For pulse mode test, maybe it is a good idea to monitor output when there is no load. How long does the ringing last there and at what frequency it rings ? One pulse should be enough so we get sort of impulse response of the system. Same test preferably for both test scenarios I listed, normal coils and bifilar type coils. This gives a hint what kind of frequencies are best to use.

ok.


1st picture is without load at 30khz waveform.
top waveform is across the primary. bottom across the three parallel secondary coils.
note the amps reading 70mA.


2nd with load. 150mA.(here comes the mr.lenz)

Behaviour seems different.


Where you measure the current, from the primary coil or from the generator ? It seems high.


Can you try sine wave input as I did not test square wave ?


One difference compared to mine is coil directions, I used CW-CW-CCW while you have all CW. Haven't tested all CW myself.


My test was such that I could not push power through the primary even if I turned to power level up so it was high inductance primary.


EDIT:
Realized that the load is a led bulb, it allows power only one way. You could put second led other way around, or a resistor, so current is not blocked.
Can you get current waveform from source with and without load ?
At what frequency current stops flowing in primary when there is no load ?
Use sine wave also for these tests.

Current readings are taken from the left LCD display of the power supply connected to the primary through small circuit(transistor).


Yes, i use only sine wave.


At good resonance point it got DC like signals(half rectified) on secondary(See the scope shots).


That is why i used LED for my load, LED does not lit when i reverse the polarity.

Input to primary is sinewave, but waveform at load looks like pulse. Or maybe I am just reading the output wrong, flat parts are in fact 0 volts DC ?


I think it is time check characteristics of your core. Couple of tests:


Feed the primary with AC sinewave and monitor current going in the primary. Leave all other coils unconnected.
At what frequency current consumption in the primary drops to insignificant levels, below 1 mA ? 30 kHz, 300 kHz ?


Next feed the middle coil with AC sine wave and leave all other coils unconnected. Same test as above.

What is needed to be added to this design is Serially Connected Multifillar wire widing in the primary.

One lenze is negated in.a coil, whatbis left to achieve overunity is concentrated magnetic field and high frequency. The High magnetic field can only be generated making Multifillar Wire and using such wire to make the Primary. You must use thin gauge like AWG#31 or thinner gauge like AWG#40 to make the multi strand wire and then connect the strands is zig zag or series. Now use very very thigh gauge in the Splited secondaries.

The reason for that is that Generators do not make electricity they absorb it from the air and pump it out for you. So you need to make your absorber a robust one than can absorb extremely high amount of Radiant Electrons.

Another way to view it is that Each metal have static electrons in them but when they receive magnetic tap flowing to and fro, they to start to flow to. And the thickness of the wire you are tapping magnetically as well as the Intensity not the Magnetic force and speed of tapping or switching will determine the amount of Current that oyou will able to generate.

Now haven gotten the idea, make sure you drive younprimarynat high.frequency in.relation to the maximum frequency of your core. Remember, the higher the frequency, the lower the Input current becomes and the higher the output current even under load (lensless winding).
