One wire,   back and forward when coiling the layers as this tk coil.

Kapanadze used stripped co-ax for this coil. Is this important??

Got it Menof thanks! I feel that we already have everything we need to do the job.

I also that think.
 

hi everyone,

I have detected 2 more bugs in the circuit.I have attached version 4.0 fix.
This time this time it is located at IGBT driver UCC37321P.This driver is a inverting version this is wrong.

Both I/C should be non-inverting UCC37322P(15volts) or alternate version TC4422 which can support higher voltage 18volts.But If someone is using 24volts to drive yoke/toriod then MC34063 is no longer needed.But need to take care of the maximum voltage allowed by both IGBT driver version which need to be connected to suitable voltage regulator eg:7815 or 7818.

Lastly the both inputs of UCC Driver at pin 2 was technically shorted to the ground using 100ohms resistors .Both 100 resistors to be removed.

Unverified and untested area in circuit portion.
{
Since i have ever worked with TL494 for PWM generator.I am unable to advise at this moment if there is any issue at this area.
PWM generator issue  base on TL494 can be easily solved by referring to other circuits.
Only pending items is the snubber components which can be fixed through experiment.
}

The on/off circuit section located at top left section of circuit presentation is purely optional which can be removed to save time.
I have not checked this section if this is functional in virtual.

To wrap it up the original circuit was merely presented as a demonstration to understand the concept maybe but without the intention for anyone to replicate.

At this point i have discovered and fixed around "7" intentionally created problem by the creator.
I am now very confident there is only 2 portion in the "circuit" to be verified TL494 section and snubber.

The nanopulser section is already completed and tested in virtual.

Tips for the day for any experienced circuit builder-

33seconds into this video do look at the simple snubber ceramic capacitor likely 1000volts or 2000volts likely around 2.2nf.This is the only one used to protect igbt driver for yoke.
I did spot a another circuit in this video which obviously using MC34063 to boost voltage either for TC4422 or UCC37322P

At 12:53 min observe it is a large toroid used instead of yoke.This is good news for us.

Bottom of tesla coil is going into large transistor 2SC5200 via blue cable.

The positive line is going into the box with 2 big capacitor likely 350volts or 400volts rated.


The negative of transistor is also connected to green strip cable which is linked to connector beneath the primary tesla coil.From there the long white cable which is mounted onto table is also leading to Earth.

The primary tesla coil 2 connection red and blue is going to transistor.There is a mini pot to provide the postive bias for transistor.

The only thing i was unable to spot is a another cable which is likely or might be hidden to provide the nanosecond pulse to the base of the  transistor.

  Dave:
  Yes, I am working on a new Mazilli/yoke to the Akula/air-coil crt now.

   I've seen the posted information above, but that is not a free energy generator.
Which is the goal, and not just a more efficient generator that still requires a power source.

  I'm still trying to understand what it is about the Ruslan crt that allows it to self run. Like, just how the feed back path works, and if it can be made to work without the nanosecond modulator, even if the output is lower, but still self running.
  I would rather buy the modulator circuit(s), as obtaining all the needed parts for it is not easy for me , here.

  Ruslan's hand drawn diagram does not include or show the feed back path. Without this loop the device will NOT self run.
MenofFather's Ruslan diagram includes the 12v feed back path, backward connected from the inverters 220v down to 12v, then back to the input source.
This is what can allow the crt to self run, once started from an external source.
I don't understand why Ruslan did not include it in his drawing.
  Is this backward connected inverter able to provide the 12v input when connected up this way???
 

Ruslan just wanted to show what is of most important to make the device work using the coils and caps and reaching resonance.
Eventually when it works just apply the inverter from 220~115V to  12V  and 10Amps or greater to the output to run the circuits.

Use creativity, use the mind and experiment, try out.

Not so difficult when applying a feed back, only need to know how much the circuits consume, know how much watts you need in 12v area or 24V setup, all will depend how Each one does it.
most of time is good to place caps befor inverter ( will act as filter ) to keep a good charge to the power supply and give the necessary 12V output.

   magpwr:
Sure man, I will look to your version 3.0. of the schematic.
Btw the snubber is simply protection  when a short occurs at the output of the yoke, that is what I have experienced.  It's protection, you guyz must have
posted something about this already for sure.
Yes looking forward to that one too. Don Smith China replication.


cheers

Hi magpwr,

IT is okay that you have not worked with TL494 circuit, so let me help that it has two open emitter outputs, Pins 9 and 10, so the two 100 Ohm resistors are the ground return path for the two open emitters, if you remove them, the two output bipolar transistors of the TL494 cannot work properly.  (Data sheet is here:  http://www.ti.com/lit/ds/symlink/tl494.pdf  )

One more thing with the resistors: it is always good when the input pins of a MOSFET driver IC see a low impedance to the ground (like the 100 Ohms represent) because in case those input pins are left with a relatively high input impedance i.e. no any termination other than a (possible higher) impedance of previous driving stage, then the inputs may pick up stray EM fields from the big output coils that can cause erronous drive signals to get through to the gates of the MOSFETs, you would not want it happen.

One more thing on the role of diode VD4 (you suggest to remove), I am not sure it would destroy both the 7414 and 7400 ICs. 
Watch diode VD1, I think it brings pulses from the output of one of the MOSFET driver ICs and notice resistors R1 (250 Ohm) and R10 (1 kOhm) form a voltage divider: these surely limit the voltage and current what diode VD4 can forward to the 5V rail what the 7805 (shown above it) insures when the 12V is present. Notice that this 12V comes from a time relay switch so I suspect that during self looping the 12V supply voltage to the input of the 7805 is OFF and the 5V to the 7414 and 7400 comes via just diode VD4, no? 
 
Gyula

hi Gyula,

I am aware the spec for TL494 and pwm ic i use SG3525 is about the same with the exception for different pin layout that's all.

There is no need to short 100ohms to ground at all.Pin 2 of Igbt driver can be connected directly to tl494.

The connection to nanosecond generator section should be connected directly from pwm generator.For me the signal diode to positive supply is not required.

Lastly if anyone notice there is 2 function nanogenerator section is providing.

1)Once the irf4905 is switched on it provide positive bias for the
2sc2500 transistor which the base is connected to tesla coil.Basically these transistor would resonate at the specific frequency of the pre-tuned tesla coil.

2)nanosecond generator is in sync with frequency around 27khz.
Think about it tesla coil is already running at it's pre-defined frequency and nanosecond pulse in kv would be present in the waveform of tesla coil.

Looks like there 3 signal around 27khz,tesla coil freq,nanosecond pulse provided for this device.

  Let me see if I understand...
   Is the power supply unit in the Ruslan's diagram the same as the inverter shown in the videos?  Does it take the AC output at the bulbs, on the output air coil. 
 And is this AC output then connected to the inverter (what is normally the inverter's ac output side???), which is then backward rectified to 12v by the inverter, and is sent back to the device input side, as a 12dc input,  to self run.
  Is this what is happening, or do I have it all backwards?

Hi Nick. Typically when people use the term 'inverter', they mean a circuit that converts
from DC to AC, for example from 12VDC to 120VAC (or to 220VAC). This is because a typical power supply
usually converts from AC to DC, for example from 120VAC or 220VAC to 12 VDC or 24 VDC, etc., so an
'inverter' would be the opposite. If your output of your circuit to your load is say 220VAC, then you would use a power supply
that can convert from 220VAC back to whatever DC voltage you need to run your driver circuits. For example, to 12VDC or 24VDC.

From what I see in Ruslan's recent hand drawn schematic, he is actually showing converting the output from the bifilar coil to DC
first using diodes and large filter capacitors, and powering the light bulbs using this resulting 220VDC. Not sure why he is doing that,
but maybe because full wave rectifying will increase the voltage to near the peak output AC voltage (if sinusoidal).
According to that schematic,  he is using this rectified and filtered output voltage (220VDC) to go to his lights and then on to his power supply,
which can apparently take 220VDC at its input and convert it down to the 12VDC output, which is powering his circuits (inverter driver and kacher driver circuits).
If it is a switching power supply, it may work fine with either 120/220 volts AC or DC at its input. Depends on the power supply.

Here is a rough drawing to show how the output power would typically be looped back through a
suitable power supply, back to power the driver circuits. There are of course other possibilities.
It depends on what you want/need.
All the best...
