Confirmation of OU devices and claims

Questions:

The blue input voltage signal ITSU shows is not a square signal.

1) Why do we use a Square Wave input in this experiment  and  not a Sinus Wave?
       Resonant circuits can only handle one frequency at a time and that is even more valid when using coupled circuits tuned to the same frequency.
       That's how radio receivers selects different radio stations from each other.

2) From this:
http://www.informit.com/articles/article.aspx?p=1374896&seqNum=7
We can assume that the ITSU  first harmonic (resonance 1.578Khz) is weaker than the (square) 5Volt p-p.

quote: "For example, an ideal square wave with 50% duty-cycle and 0 v to 1 v transition has a first harmonic amplitude of 0.63 v."

ITSU 5Volt p-p >  5x 0.63 V ( Nota Bene; ideal)  =3.15V    ( RMS or p-p )


Vortex1 (all)
3) Does the the coupling factors or total energy transfer  be different  in this case maybe because we use a transmission (coupling) from
the coil part in a series resonance circuit (gen.)  to a parallel resonance circuit

  compared with (common radio)  parallel resonance circuit coupled to a parallel resonance circuit(s) ??

My guess is that they are equivalent

Excellent post Vortex1.

If you want to build
the bigger coil pm me and I will give you the specs. (You also need 5nf caps in parallel with each receiver coil.)

Hi king-o-reso ! I am interested on the specs you mention. In particular the gate driver, which I have right there before me but I'm unusre of the soldering so the schematics to be able to rebuild one one day. Could share them may be privately if you find it more relevant ?
Thanks a lot !!
Yours sincerely,
Benfr

So #344 related :

Mutual inductance

Coupling factor or coefficient K

Turns ratio

The K factor easy demonstrated : the attraction/ repulsion force between two permanent or electric magnets                                               
                                                                             dependent from their distance

Why and how shall the device generate surplus power?  Mathematically and physically. ?
How do we treat " inrush" , like a resistanceless superconduction. ? Inrush pulsation  !

Using lamps as indicator :

Gyula,

The DC resistance of my coils are 1.5 Ohm.
Its gonna be fun then tuning the 6 coils for max. performance 
By the way, the frequency is of course 1.578Mhz, not 1.578Khz.


LancaIV

So the first question : how much real input power ? pulsed P to P = ( UxZ)x(IxZ)     = 25,6 mW ?

I let my scope calculate the instantaneous power over the signals (voltage/current) it receives, should be OK.


Vortex1,

thanks for the info/comments, they are appreciated.
Lets see what happens when adding the additional coils.


Seaad,

The blue signal is originally a square wave, but gets distorted by the resonance it encounters.
We need a sharp on/off time of the pulse for the magic to happen it seems, so a sine wave would not do that.
