Guys, true or false...

The purpose of the PLL circuit is to achieve the highest current possible across the induction heater coil.

If the above statement is false, then what is its actual purpose?

If true, then couldn't we simply sweep the frequency with a SG and manually find the resonant peak using a scope and current probe?  And as long as we use a fixed load is there any reason the resonant condition would wander out of tune?  Or is there something in the way this device functions where the frequency is constantly moving back-n-forth?

I completely understand this PLL circuit will track if you are constantly changing the load, but is all that necessary for one of us to demonstrate a working prototype?  Just seems to me it is overkill for finding and studying the basic effect.

Good day DogOne

Yes, good point.......... but with my PLL creations I find that Temperature variations not to mention grounding configuration, ie; relative ground planes in relation to DUT and even RH will cause the Fres to meander around.

PLL or a Direct Feedback method will keep locked (within a certain range of course) the Fres.

Although it appears so, nothing is really static or separate........

The main PLL purpose is to keep resonant condition in yoke driver no matter how load impedance changes.
The secondary PLL purpose is in this specific case to stick Tesla coil driver ON/OFF signal states on specific point of sinus wave.

lost_bro,

thanks for that info, i can't remember seeing that before.

Quick edit:  Should read Pulse Pin #1 NOT #4 on schematic....... was in a hurry I guess and mistyped the pin #.

Good day All

Food for thought:

I agree with T-1000 on the *critical* timing issue regarding the *apex Sinus pulsing*.

Here is why:

In the Olegg schematic TypeII comparator PLL is used: Pin#14......... this is opposed to TypeI comparator PLL on Pin#2.

WHY??   TypeII comp. PLL (pin#14) will ONLY lock unto the Fres and NOT subharmonics nor overtones of the principle frequency.  This is very distinct from the operation of TypeI comp. PLL on Pin#2, as TypeI will lock to subharmonics.

TypeII comp. PLL is less noise immune, hence the custom made PCBs with ground plane.... TypeI has a much higher noise immunity.  So TypeII requires a little more effort as far as layout and design go..... if it did not matter it would be much easier to implement TypeI PLL.

So apparently there is a *reason* for using the TypeII comp. PLL ...... maybe exact timing/synch (non-harmonic) is necessary after all

being that I am too lazy to re-write what I wrote about this many months ago I will just paste and copy my old post:

Good day MagPwr

Good to hear that you enjoyed the videos.........

Want to take advantage of the moment and make a couple of comments on the schematic that you posted:
As we know it uses Pin#14 so it is TypeII PLL, which is different from TypeI PLL on Pin#2 in that (@ resonance) *EDIT should read* (through VCO range), both the signal and comparator input are in Phase = Zero shift.  Of course the draw back to Type II is that it is very much more sensitive to EMI and sloppy board layout than Type I.

I used TypeII PLL in my SSTC design also... All the other TC designs I have seen on the web use Type I exclusively for that very reason (EMI problems).  The type I really requires much more circuitry to implement because the phase shift is variable 180 degrees through the VCO range. (90 degrees @ center VCO). 

Type I will also lock onto *harmonics* or overtones of the principle frequency, Type II will NOT lock on *harmonics*.

I took the liberty to comment a couple of items on the schematic, please see attached *commented* schematic.

Take care, peace

BTW:  The correct name is - Mazilli. The Italian guy's last name that designed that oscillator circuit.

Nooooo, the correct name is Modzillaaaaa grrrrrrr
