Partnered Output Coils - Free Energy

[EMJunkie]

Brad I just want to thank you for sharing the mountain of work you have shared on this. Very educational for a lot of us I'm sure on the rigour you apply to testing.

I second that Jimboot!!!

Tinman aka Brad is a Champion, leading the way for so many!

Brad is showing how important it is to do simple experiments, look for small things, investigate the assumptions made by so many!!!

Thanks Brad!!! Let the Aussies lead the way!!!

One test that would end all doubt would be to connect the output in phase back to the input using a potentiometer to adjust the positive feedback. We can treat the device as a transfer function with unknown gain.

Now  just hitting the primary with a pulse, i.e a brief connect and disconnect from a small battery should cause the transformer to briefly ring at it's "sweet spot" frequency. This is called "shock excitation" or "step excitation" like hitting a bell with a hammer. Normally in a system with gain <1 you will see an exponentially damped ringing oscillation at the "sweet spot" frequency. You can capture and observe this on your scope.

You can then observe the decay rate of the primary ringing frequency on your scope as you adjust the amount of positive feedback with the potentiometer.

If there were truly gain >1 in the system, the decayed oscillation should at some point turn into either steady state or exponential growth of the waveform when the proper amount of feedback is applied, as is true of most systems that amplify.

This is the litmus test for a system with gain >1. Since the windings are 1:1, and it is an AC system, it should not be difficult to perform this test.

OK,so we must keep the output in phase with the input-easy enough.
Then we have a pot to adjust the positive feed back.
Then we pulse the primary coil with a current-this is when the trouble starts. How do we stop that pulse also going straight into the secondary that is feeding back to the primary without the use of a diode?

Then there is the issue of the voltage/current phase shift when supplying the primary with power,and no phase shift from the secondary supplying the power.

Good question.

If I were to attempt to loop this device (and I will be), I would use a simple sine wave generator (have one on a single chip), pump that into a small audio amplifier (have one of those too) into the primary, then out the secondary through a full wave bridge rectifier into some filter caps and back around to power the oscillator and amplifier.  That last step I would insert a voltage regulator just in case of the possible runaway condition.  Then all that is needed is a bump start at regulator voltage.  If the gain is more than the losses, she should purr like a kitten.  If not, one should still see a fade down until either the oscillator or amplifier drops below its running voltage.  The fade down can be compared to the no loopback condition to get a feel for how much more gain is really needed.

Based on the numbers Brad has posted, if this Hybrid Toroid will function in the power range needed by the electronics, its gain should exceed the losses of the electronics by a small margin.

I think it is more an assumed error,as the results go against what most believe to be true.

Tinman,

That's a bit harsh.  Did you follow what Partzman was indicating in his post by way of his various calculations of Pout using your measurements?  Your resistance and/or voltage measurements have significant accuracy issues that need to be addressed.  The various math cross checks of Pout that Partzman provided are not in any way an "assumed error".   

Keep in mind that purpose built and utilized transformers with an efficiency as high as 99.75% are not unheard of.  With that kind of efficiency possible, consider the required measurement accuracy.     

If i cannot use my DMM to measure the resistance of a resistor,then how do i find that resistance value?.

You can use it to measure to the accuracy provided by the DMM.  What is the accuracy spec of your DMM when measuring 10 ohms (or 100 ohms)?  Typically this spec is stated as a percentage error plus a given number of least significant digits.

Keep in mind that two wire resistance measurements include lead and contact resistance errors.  More precision is attained with four wire resistance measurements by separating the current source from the Vdrop measurement.   

Possibly I am not remembering correctly, but in previous videos I have noted that when your scope is connected to your FG, the FG's output level display and your scope's measured value seem to have a significant spread between them.  Have you ever looked into this?

It doesn't matter if the step pulse also goes to the secondary, the pulse is mostly in phase and will be limited by the feedback resistance. No diodes are needed, and a little phase shift will not keep it from oscillating, may even enhance oscillation, all subject to whether there is truly a gain>1.

In any closed loop system with negative feedback, we observe the stability criteria by noting the overshoot and ringing due to phase shifts and transit delays in the amplifier that the correction mechanism (feedback loop) tries to correct.

For systems with positive feedback, if they are DC coupled they will latch up to either a high state or low state.

Since this is an AC coupled system (a transformer) latchup is not possible. If there is enough positive feedback power available, the core will momentarily saturate, then snap out of saturation, and you will observe a square wave oscillation as the process repeats for both positive and negative portions of the cycle. This is what a blocking oscillator aka Joule thief does.

But since the claim is a gain in the transformer >1, no current amplifying transistor or power source (battery) should be needed, oscillation can be had with just the positive feedback.

With less feedback, you will not saturate the core, and a quiescent oscillation will be observed. All of this is subject to the amplifying device (your transformer) having a gain>1.

This is the tip of the iceberg known as "Oscillation Criteria for Amplifiers", worthy of study for serious researchers.

The step response required to perturb the system is easily accomplished with a 1.5 volt battery and momentary switch.

Since the claim is that the transformer is an amplifying device with a gain>1, this is extremely easy dynamic test method when measurements seem to have hit the limits of the equipment on hand.

P.S You can insert a capacitor in series with the feedback pot if you want to block DC from getting to the secondary, you will just need to hold the switch on untill the cap charges. I really don't think it is needed though since DC applied to both windings will charge the core in the same direction.
