Use   arduino
3 digital ouputs
2 of them will be push pull use them with high speed driver ic and FET.
1 of them will be tesla nano pulse generator use ic to make 500 ns pulse and FET.

step 1. find resonance of your yoke... by sweeping frequency monitor input vs output. arduino driving only 2 ouputs of push pull yoke.
Mine is 25 khz   40 microseconds between push and pull. cycle complete push and pull in 80 microseconds. frequency on output is 25 khz
most efficient pulse width is between 13 and 26 microseconds.

step 2. use step 1 to determine tesla harmonic frequency 25k *2*2*2*2*2*2= 1.6 mhz  (choose the multiple closest to 2mhz)

step 3. use step 2  to determine 1/4 wave of 1.6mhz (146 ft or 44 meters)  Lengths will be determined from this number. 1/2 of this is tesla secondary length (22meter), grenade length 44meter and 44 meter large ground wire . 11 meter length on the induction coil wrapped on the grenade.

Good day Bat1Robin2

A quick question:  Are you sweeping the yoke frequency spectrum looking for the *Ferroresonance* of the yoke core ferrite material, or are you *using* the yoke & windings as the *L* reactance of a L/C resonant circuit?

If you are *sweeping* for the Ferroresonance of the Yoke Ferrite material I would guess it to be in the Mhz range.
Maybe 25Khz could be a sub-harmonic of that Mhz range ferroresonance.

If you are using the Yoke & windings as part of a L/C resonant circuit,  exactly what forms the *C* reactance?

Have you *checked* the Frequency Spectrum of your _Grenade_ coil?

We have found that only small changes in *winding* technique can and will not only completely CHANGE the S/N (signal/noise) ratio of the higher order peaks but also the predominate resonant frequencies of those peaks.

Even if you use an *exact* length of wire equal to Lambda/2;  you are NOT guaranteed that the *predominant* resonant frequency will coincide with Lambda/2.  In fact I am certain it will not because different grenade *winding* techniques will render *unique* apparent phase Velocity Factors which can modify / shift that desired Lambda/2 resonant frequency.

Meaning that without the use of a Spectrum Analyzer, it is at best very difficult to analyze if not impossible to predict the Resonant Frequency and S/N distribution for any particular Grenade winding configuration.

With that in mind, we have found that it is much easier to wind the *grenade* first, analyze the frequency spectrum distribution and then work backwards to calculate the _inductor loop_  Fres (resonant frequency) and likewise the Push Pull drive frequency.

take care, peace

My thoughts on yoke analysis is like this. if you monitor input power and output power of any transformer and sweep all frequencies and find the one that if the most efficient then that frequency must be its a resonant one. Similar to pushing someone on a swing set at different times you will soon find what timing is right. One does not need to measure the gravity of the earth or the chain length to find this out by experimentation. You only need to monitor how far they go when you make a small push. My yoke core begins to eat power above 60 khz. and below 10 khz will not output much of anything. So i do not need to know L or C to find the most efficient operating frequency of a transformer yoke. But i believe you are correct in that it may be 50khz. My arduino cant  reach that frequency. But i know from previous experiments that in that range output begins to fall. Pulse width was also determined to be best between approx .33 and .66 of each push pull time.  Again someone does not need to know the permeability of the core or anything else to find this from experimentation. That being said i do have a small capacitor connected parallel to the output winding but it makes very little gain didn't think it was worth mentioning. I tried a larger one and my efficiency fell across the band so i left the little one. By sweeping with a computerized arduino and monitoring efficiency is that not somewhat the same as a frequency analyzer ??

My electronics teacher told me to find the mystery components R and C in an unknown box and so i wrote a computer program that had all possibilities of r and c where the my computer generated graph crossed was the only solution that fit the box known criteria. It ended up being the correct answer but i was suppose to use a complex super position formula or something like that instead. There maybe more than one way to skin a cat. Tell me your steps to the solution then i can compare.

   So, one step forward, two steps back... wasted effort on the part of Ruslan trying to replicate Akula's device on that last video. Nothing new there.

    So, now I've got my TL board wired and running on 12v to the TL494 circuit, as I had burnt out both of my previous voltage regulators, so I replaced the 12v regulator and filters with ones I had on hand.
I also connected the fet drivers up to the 12v regulator, instead of the 15v regulator that I had on previously. This was done until I get some new regulators which I've already ordered.
   I also reversed the yoke primary where they connect to the fets. However, there was no change noted from that reversal. My fets are still getting very hot, so much so that I just burnt another one.
   However, there was NO heating of the fets when I disconnected the yoke coils from the fets. The yoke is still connected to 24v.
   The second picture is one that I took just now, showing clean signals from the TL circuit. But, not so nice when I connect the probes to the gates of the fets with the yoke connected, as well.
   Perhaps someone can give me a hand to try to figure out why the fets are frying, with only a few seconds run time.

  BTW: Hoppy, I do get a better interaction from the Kacher to the induction circuit when I removed one of the fets (that had burnt out), as you had also noted previously, as did apecore on that video that he had made for you.

   My signals from the TL494 don't look too bad now, and I do have some interaction with the Kacher, but nothing to write home about.
   Here's some pics,  let me know what you think.

Nick,
Your frequency is way to low, which in turn makes your pulse width way too long. (your scope appears to be set on .1 milliseconds per division)
Your pulse width appears to be 100 microseconds as i stated i have determined most efficient pulse width is 13-26 microseconds. your yoke will not be far off from mine.
crank those drive frequencies to 12.5 khz push & 12k hz pull to get out 25 khz output with pulse width about 33% that will get a starting point.

I have done arduino computer driven control with precision microseconds testing trust this info.

If you drive any coil with too long of a pulse it is the same as a dead short current will skyrocket and fuses will blow. stay under 26 microseconds on those yoke coils or you will be sorry as efficiency will drop like a rock. I also recommend a power supply with current limiting.

short pulse always better to start off then go longer.  show your scope settings more clear next time.
