Kapanadze Cousin - DALLY FREE ENERGY

  What I've seen on my Mazilli/yoke set up, is that if I use the yokes thick 3 turn output coil to give power to the 12, 12 turn air coil,  it only provides for very low voltage output. Even if this 3 turn yoke coil is connected through a tuning cap in series (or parallel) with the 12,12 turn air coil, there is not enough voltage to run my 100w bulbs from the 48,48 24,24, 12, 12 turn air coil's output coil. 

  So, I decided to use the 3 turn coil to power the kacher crt, instead. Through a cap/rectifier bridge providing about 12v output to the kacher crt. And use the yokes (red) 20 turn output coil to power the 12,12 turn air coil, instead.
This is different than what Akula/Ruslan have done, but it works for me,although I don't see the device self running, but,  I don't have the nano modulator crt, yet

hi Nickz,

The "suitable yoke" core setup which you have with 3 turns as output is meant to be powered by 2 IGBT's each with snubber circuit consisting of (600/1200volts diode in parallel with 150 ohms resistor) and this is connected in series with high voltage 2n2 ceramic capacitor( around 630volts) from drain to source of IGBT.Additionally IGBT is to be protected by a 600/1200volts diode .

I have attached an image of the Akula's snubber circuit which i can understand to reverse engineer.

Not forgetting the center tap of yoke core is connected to recitifed output from the 220volt inverter.
IGBT to be driven by PWM generator with nanopulse or narrow pulse or around 4%...15% duty cycle.Frequency was unknown but my guess it's around 200khz range.

Your Mazilli circuit is out after finding suitable yoke core which you have already completed.

The 3 turns output would produce around 1...2kv(Last tested in virtual last year) which is connected to microwave cap in series to those layered coil eg:48,48 24,24, 12, 12 which would likely produce reasonable output to drive a mains bulb.

Unless someone else got even more productive response please do assist to contribute.

Negative mindset won't assist anyone in obtaining new discovery.

------------------------------------------
In the meantime i'm working on Don smith China replication.
Completed the biggest headache the largest circuit circuit board i have ever built 7KV high frequency switcher using 220khz...230khz to switch 6x 1200volts CREE IGBT in series driven via 6 xFOD3180 opto-coupler.

Found a small bug in my circuit only after connecting all the opto-coupler inputs together via resistor for each one which prevent proper switching of igbts if connected in series.
2 possible solution to be tested out  in the next few days.

Hi Magpwr. The schematics that were posted for this circuit (their accuracy is questionable) had the MOSFET snubber
resistors at 7 or 7.5 ohms.

The inverter driver circuit, using the PWM chip to set the frequency and pulse width, is not a nanopulse
generator. It is generating a square/rectangular wave at likely 50% or less duty cycle to drive the series resonant circuit of the
primary coil. Since the primary circuit is a resonant circuit, it should be producing a fairly clean sinewave on
the primary coil if driven at a frequency close to resonance.

Is this the Don Smith demo circuit which has the center tapped secondary with the primary at the center,
and with the large capacitor bank at the output? Do you have a schematic of the circuit you are building?
I hope you are aware that having a large capacitor bank charged to a high voltage can kill you instantly if
you touch a terminal or connecting wire on the high voltage output capacitors. Such a cap bank charged to
high voltage can produce a huge current that is very deadly. If this is the type of device you are building, you are
really going to need to take extra precautions in working around this circuit.

hi Void,

Having a high contrast hd Samsung monitor allows me to see the components eg:resistor value quite clearly in the photo as compared to using laptop's screen.
They have shown 2 version of the circuit in the  PJKBOOK.pdf at page 288/289.Alternative do search "salty" in pdf file to get to the required page .

The snubber circuit shown in page 289 tallies with their photo of the actual circuit base on components eg:resistor value which  i can see and compare.
They are using 5.1ohms to drive igbt.But cree igbt base on datasheet already got 5ohms internal gate resistance.

Base on my more recent reverse engineering of the UC3825N PWM generator which i have attached base on the component used regardless of capacitor value.The duty cycle is around 40% which can't be changed, only the frequency can be changed via the blue trim pot.

You mentioned-

Ans-Their center tap is the center of the b&w coil which is continuous and isn't cw/ccw.This version differs from the original Don smith version and mine.

I have attached my super basic version of the Don Smith which is switched by 12volt battery which i created for someone in this forum previously.

The higher voltage version of around 60volts which is supplied by 12volt to 60v boost circuit would create interference with the digital fm radio band-mhz which is placed around 3meter away once 1/4 resonance is applied at secondary coil.

                Don Smith device-Short circuit test demonstration   http://www.youtube.com/watch?v=z-MZSavyM8U

The objective of this video of mine is to show there is no effect on primary current drawn even after shorting output with screw driver.

Every experiment has it's risk especially HV.


If i choose to stick by the "school book" then no new discovery or no new invention would have been been made.
