Partnered Output Coils - Free Energy

[MileHigh]

Sorry, but the FET switches OFF at point E and it switches ON at the beginning of point B.  At the end of point B the FET has sucked the last bit of energy out of L1.  Then D1 switches off, and the potential reference for channel 1 switches to the +6.7 volts coming from the other direction.  As L1 charges up, the 6.7 volt source starts to sag, and that's why you see the drooping on the channel 1 waveform during phase D.  At least that's my take on it but I am open to correction.

I see you have beaten me to it. I was getting ready to post the same thing-- the probe connections as shown in the schematic do not appear to me to be a legitimate "output power" combination. That is a big Red Flag.

There also remains the question about whether the scope's channel "Probe attenuation" setting is even appropriate for the CC-65's 1mv=10mA voltage/current output. The scope's default is 10x. Is the channel set to 10x or 1x? Do we read the mV values indicated on the trace directly as mA, or do we have to include a factor or divisor of ten in the reading somehow? 

You know for sure that if I were doing tests like these, I'd show real comparison traces from the voltage drop across a proper inline current-viewing resistor compared to the CC-65's readout on the same circuit ... just as I did in the "pitfalls" video where I use both types of current sense systems on a Joule Thief, using the Lecroy DSO and a high-quality current probe. Which video also incidentally shows how just moving the voltage drop probe's ground lead three inches along the circuit wiring radically affects the amplitude of the measured signal.

TK,

The channel two current waveforms do make more sense if the scale on the current waveform is actually 50mv per div instead of 500mv, which would be consistent with the scope being in its default 10X probe calibration.

If channel two is actually indicating 50mv per division as above, there remains an apparent offset of 40-50ma at the current waveform's minimum.  Possibly this is offset in the current probe output (or scope channel input offset).

Irregardless, as MarkE and yourself have already pointed out, due to the probe connections used, the Ch 1 waveform does not indicate the voltage across the 10R load so no information regarding the power dissipated by the 10R load resistor can be determined.

In short, the waveforms provided do not allow a determination to be made regarding the circuit's efficiency or in any way lead one to believe that the circuit's performance is unusually efficient or overunity.

MH,

I agree.  Q1 switches off at "E".

I believe the turn on of Q1 likely begins at "C".  In other waveforms EMJ posted regarding his smaller three coils on a ferrite core setup, that negative going rectangular glitch that begins at "B" is also observed in the rectangular drive waveform from his driver board (I believe that is what he was using).  Possibly the glitch at "B" is more so related to the driver's waveform.

Either way, at "B" or "C", Q1 is turning on.

I agree with Vortex, the wave form looks almost like any other chopper wave form that is scoped across the mosfet drain and circuit ground/negative.

The circuit coasts at the supply voltage then at the beginning of point "B" the mosfet turns on and then turns off at the end of point "B" the primary then discharges causing an initial spike at point "C" then the coil discharges through point "D" and all looks perfectly normal for a mosfet drain wave form of a chopper discharging through a resistance, then at point "E" something lets go and there is a seemingly free unclamped oscillation for a small time.

Now part of the primary wave form could be seen on the secondary possibly so the trace may have been derived from somewhere other than a mosfet drain. But to me it looks like the same waveform I see on a mosfet drain of a chopper but without the crazy ringing at the end of the cycle.

You are as shrill as ever.  Since you had but the load resistor and it being highly inductive, my statement that it is not suitable as a current sense resistor stands.  The fact that you do not show a suitable current sense in your drawing raises question as to how you ever obtained measurements that led to your COP of 1.7 claims.  The CC-65 only has 20kHz bandwidth and its noise floor is about 10mA making it a very poor choice for looking at current.  Your voltage probe does not reference the voltage across the branch that you measure your current in, making power measurements based on the two useless.  Personally I think this has all just been your private joke on OU believers.

Hahaha you're funny! Don't tell me, All Test Equipment is a "very poor choice for looking at current"? Hahaha you're just Funny!

Just in-case, my Current wave form is 1.7Khz - WELL Within the Meters specs!!!

Its built and designed by experts, but its a "very poor choice for looking at current" WOW youre a total fool!

Next you'll say Fluke instruments are really UFO's!!! 

Personally I think this has all just been your private joke on OU believers.

Personally, MarkE I think this is the most ridiculous statement you have ever made! It shows you are emotionally charged, you could be suffering from more emotions than a 12 year old girl with her period!

It shows, that in all your self proclaimed greatness, that you have no evidence to say in your self proclaimed greatness that there is an error there!

You can not say, an nor can anyone else, "Its Fake", and all can see that "Something" is in fact going on here and investigation needs to be done!

It burns you! That someone like me, can come along and stump you outright! It really burns you doesn't it MarkE!

So you have to through ridiculous statements around about Test Equipment and Probe connections!

Well MarkE, the joke is on you PAL Stumped and Humped! Good luck with your emotions! They oose jealousy and self proclaimed needs!
