Reactive power - Reactive Generator research from GotoLuc - discussion thread

[poynt99]

I don't mean to interrupt; but you're using a DC source there... what about when it's AC?   Does inversion really matter?  Normally it will compute to be all on one side of zero; adding capactiance skews it so half of it is negative... how do you get the inverse in DC?

If one is making a claim based on the polarity of a number, then yes polarity matters, regardless if it is an AC or DC circuit. Average power is average power. It can be negative and it can be positive in either case.

cpaz, time's up my friend.

I'll not be lowering myself any longer to converse with you at your level."


Does that slot me, in your mind, above or below the Illuminatti level ?




" The bottom line is this:

If and when you can refute anything technical I have said in this or Luc's other thread, then I may engage. Otherwise, you may as well go piss in the wind.  "


Interesting that you wood employ the term 'piss'...as luring builders into pissing contests just happens to be your method operation. 

You continue in the present manner, I will call you out...and your massive ego will not permit you to resist defending your faux honor.

And thats just the way it is, and the way it will play out.

We all must learn to accept certain realities.



" Now, back to pertinent on-topic issues...

We shall see.

I've done a quick circuit with a transformer as AC source, the secondary feeding a RC series exactly like Luc minimal configuration.
I took scope shots and instead of using math function U*I like any honorable academic, I used function U/I. Why? because I wanted to see what power source sees. The scope shot is attached, "tan.jpg" naturally looks like tangent function in trigonometry. Another reason is because I don't trust the sophistication of a DVM (sorry PoyntyEgo) when I try to understand what I present.

The Red trace is the voltage, the Yellow is the current and the Green trace is U(t)/I(t) function.

Ladies & Gentlemen, I present you the Negative Impedance shown as the negative spikes in the green trace. Briefly you may remember the efforts of using of negative resistance exhibited in semiconductors by many researchers. I'll let you contemplate about natural occurrence of the phenomena in these circuits. Effortless! Other implications I will let you contemplate on your own, I will not try to impose.

For some other people that are more familiar with graphs used on semiconductors data sheets (I function of U as X and Y coordinates) I attach another plot "xy tan.jpg". "Those skilled in the art" will recognize the regions of negative resistance.

That was with the intent of moving forward, enough with chasing our tails on issues of minuscule importance.

Thank you barbosi for you test and sharing your interesting results.

I hope this will help move things along.

Excellent work! once again, thanks for sharing

Happy New Year

First I apologize for going back on my word about not posting any more here, but I just want to ask a simple question to Barbosi, so that I can improve my knowledge.

Barbosi, can you please clearly define what exactly is negative impedance ?

Cheers
