Kapanadze Cousin - DALLY FREE ENERGY

[verpies]

the 160Volt zener diode between ground and drain gets too hot .. I have around 176-180volt on the Zener.

That is because, when the MOSFET opens, the Zener diode must dissipate, as heat, all of the energy contained in the inductive spike.
Instead of converting that energy to heat, you can recycle it back into the power supply like this, thus not much heat will be generated.

Also, you can minimize the energy contained in the inductive spike. More about it is below:

What you mean by "yoke can be tightened up" ?

It means to increase the magnetic coupling coefficient between the primary and secondary winding.
You can gauge the coupling coefficient by shorting the secondary winding, and measuring the inductance of the primary.  Ideally you should read zero primary inductance when the secondary is shorted (or the smaller the better) and a large primary inductance when the secondary is open.

Increasing the magnetic coupling coefficient ensures, that all of the magnetic flux generated by the primary winding penetrates the secondary winding.  This maximizes the transformer's efficiency and minimizes the leakage inductance (which is proportional to the flux that DOES NOT penetrate the secondary winding) which is responsible for the energy content of the spikes, that your dissipative snubber (the Zener) is trying to get rid of as heat.

Visually, the flux leakage, that is responsible for the leakage inductance, is depicted here.

What can i do to reduce noise ?

Minimize the leakage inductance. This is the same as increasing the magnetic coupling coefficient.

Good day Zalmoxis

Please review the attached photo of the yoke windings.... for reference this build has a *tighter* design, but is NOT bifilar with center tap as recommended by T-1000.

To measure the Current waveform:  current is proportional to voltage across a resistance, so place a Series power resistor (.1 ohm or less & preferable NON-inductive) in the Inductor loop, at the point you want to measure the current waveform...Then connect your scope probes across the resistor.  You will notice that the waveform across the resistor is approx. 90 degrees out of phase with the voltage reading of same inductor loop. Be aware that the Current waveform taken from across the resistor will *flip* 180 degrees from  one side of the _Capacitor_ to the other side of the Inductor windings in the same circuit.

Or you can do exactly as A.G. said and use a CT, (current transformer), ie; small toroid with many turns with *Burden* resistor placed across output of Toroid secondary and scope probes placed across *burden* resistor.  This should be sufficient to *see* the current waveform...... be advised the if the CT is placed reversed over the _inductor Loop_ wire, then the Current waveform will be 180 degrees out of phase.

PLL; Phase Lock Loop, ie; CD4046BE , 74HC4046, etc.

take care, peace

Lost_bro, all,

verpies pointed me to this picture1, but please be aware that the drawn yellow arrows are WRONG.
Its explained in this part of the thread:
http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg474562/#msg474562

In fact the blue primary is wound ALL in the same direction and not bucking as it LOOKS like on this picture1.

See picture2 from the same video but taken later where you can see that the winding continues in the same direction.

Regards Itsu

@verpies thanks , that back emf .. somehow is under under control stays around 120Volt with 20-21Volt on the PSU and with perfect pushpull dutycycle and resonant frequency.
@AlienGrey i will make some tests as @steadyfield said about sync tesla with the current peak. In few hours i will post some new tests.
As an ideea .. do the grenade coils need some resonant capacitors ?
On the schematic from Seregey he uses to transfer from the yoke to the inductor 330nF + 330nF + 470nF = 1,130uF .. for my perfect resonant at 23.5kHz i use only 330+330nF = 660nF .. Sergey uses on the grenade around 2 X 330nF in series = meaning 165nF .. should i use the math rule of three and to use a 96nF on the grenade coil ?

If i put any caps with a value bigger than 100nF .. i get a drop on the output voltage.

what are we aiming at? .. powering 100watt bulb at 220Volt and 0,45Amps DC with input of 24Volt pushpull @4Amps = 96 Watt input?
Somehow using 100 Watt we have to push out some 150-200Watt.
I have a rectifier diode bridge made of 4 HER306 .. schottky diodes supporting 3Amps .. SHould i also try to connect the bulb directly on the output of the grenade?

WOW !
i've measured the current entering the inductor coil , yes is it true it has a different PHASE than the Voltage!!
Check the attached images, the yellow - current , light blue - voltage after the capacitors, measured between ground.
Dark blue - tesla driver output.
I am unable with the jumper setup to move the tesla pulser on the peak of the amps ..
i've played a bit with the pushpull frequency and duty cycle and simmetria duty cycle and i've been so close with the tesla near the peak of the current , see second attached image.
Ok i've also played with tesla установка длительности пачкогена "ustanovka dlitelnosti pachkogena"  and i've found this strange noise on the voltage light blue see 3rd attached image
Why do i have 2 blue and 2 yellow waves ? Is it an error or something is happening ?

While i was playing with that multiturn potentiometer i've started hearing noises coming from the tesla transistor 
Now to the tesla controller are going 67mA @78-80volt!
What is the limit of the 2sk2611 transistor .. how much on voltage can i go up .. and why do i hear noises from that transistor mounted on the heatsink ? The bulbs are connected in parallel directly on the output of the grenade without any capacitors.
I've connested to test a 90nF capacitor .. and the light is almost not visible on the bulb filament 
I will play tonight with some pushpull with ir2153 to be able to fine tune the voltage going to tesla wish me good luck ...

the 2sk2611 is a 800 volt 9a device you can get 1200volt devices now but thats a lot when your talking about fly back you need some kind of voltage limit circuit to re cycle that fly back
