The bifilar pancake coil at its resonant frequency

[synchro1]

Thanks for the clear explanation MH.  I have used your analogy of a coil and flywheel several times times since you first told me about it several years ago.  Most people understand that analogy better than the conventional explanation.  The only exception seems to be the ones that stubbornly stick to the idea that the current reverses when the coil discharges.  For some people there is no hope they will ever learn.

@Citfa,

I have a quote from you on my "flyback current reversal" thread over at Energetic Fórum as Allen Burgess, where you impudently state that current runs in one direction and one direction only in the Ruhmkopf coil secondary. Do you still cling to that outrageous and pig-headed claim?

@Partzman:
I know you have a lot of experience in these matters, so I am also, along with MH, surprised that you are not questioning your scope's "numbers in boxes". What happens if you apply some low-pass filtering to the signals before you do the math? Does your "overunity" result reside solely in the spikes and ringing? If so, does that tell you anything significant?

I have scope traces (on high-end Tek and LeCroy oscilloscopes to boot) from absolutely positively known-to-be underunity circuitry that also "show" overunity results; specifically, a _decreasing_ energy integral over time. I can haz cheezburger now?

It's really too bad that we can't run anything on pretty coloured wiggly lines. However, if you can do the elementary calorimetry experiment that MH has outlined, and obtain a string of positive results, it would carry a lot more weight than your scopeshot.

So... you are EF's Allen Burgess? That explains a lot, for sure. You get yet another ROFL, and nobody will ever look at your posts here in quite the same light again.

@ MH, TK, Zephir,

Yeah, you guys are right!  Only a fool would rely on stupid scope measurements and I wanna know, how do these guys at Tektronix sleep at night?

Lol   Nowadays we are arrested for having and not having.
If you do not show them any shot scope, they would ask for those same shot scope ...

Then they will say that it needs to be validated by people competent for this work ... I can only think of someone with enough knowledge to do this validation, MH or TK Team marvel. or should i call cheezburger team ?
