   Lost_Bro:
  There are many different PWM circuit on the market that do also offer frequency controls. Ebay has many available.
   The one that you linked to is only 8 to 12v, but there are some that will go up to 30v. Of course the price
can go as high as $20- $80.  But, some of those are high amperage models, even for induction crt, possibly well suited for our purpose.
   My time is also worth something, and I'm not really into building a circuit that can be bought, and used immediately. Especially if it can be purchased at a reasonable price.
   That's what Ruslan has been doing all along, probably paying someone like Aleg to design them for his particular purpose.
 
   I wonder what would happen if an induction hob is used, once modified, instead of the push-pull oscillator. As they are much more powerful, as some guys have seen, like Igor Moroz. His tests with using them, to light 2000w worth of bulbs, using only 500 watts input. Looping it has still been the main problem up to now, as most guys that have used them, have noticed.

Good evening Nick

Yes, the pwm that I posted is *only* a small signal driver, and as such one must connect the output of this tiny 3525 pwm to the  appropriate *drivers* and MOSFETs/IGBTs in order to handle the power switching.

The 8-12 vdc only refers to what the IC on the pcb requires for pwm output..... what you do with that pwm output is up to you.
I don't remember exactly now, been a few years but,  I believe that IC has a integrated UVLO which trips @ 8vdc.....

The UC3525 is an OK pwm, but actually I prefer the UC3825 which has a higher top end == 1Mhz.  Albeit, both chips are very old.

take care, peace

   Thanks for the info on the oscilloscope.  But, that scope is already grounding out it's HV from the flyback to ground,
and would  not last very long here at the beach. Nor do they include a shipping price to C.R. which will be much more
than the scope costs.
   I have been following the used scope listings on Ebay daily, so no need to look for me, but I thank you in any case. 
  There are better deals on Ebay to be had, and I'll get a scope as soon as someone can bring me one,
that I'll buy from Ebay.

   As it had been raining here for a couple of days, my three separate ground lines worked a bit better,
than when it doesn't rain. Which indicates to me that my grounds are not working as well as they could be, 
even if I add water to them everyday.  So, better grounds are needed to see the effect of ground pulsing,
or it's antenna type of return effects.

  The feed back loop's return path should be adjusted to provide for at least 24v back to the input,
even when it's simply started with a tap of the battery, to kick start the device.  I can now tap the battery
and the lights will come on, but only if I use a 12v wall adapter at the same time, which provides the input to the
Kacher crt, as well as to the yoke. The 2 amps (24w total input)  will light two incandescent bulbs.
I'm still working on this... but,  this is one very interesting and very complicated device.
Anyone with little patience, will never get these devices to work right, even with the help of a scope,
or a spectrum analyzer, etz...

is 3000 pixels wide, and these wider images WILL mess up this thread.

Nick, I will be assembling my device over the next couple of weeks.  If you could do me a big favor...

Try to document the tuning steps you use and the dependencies of what effects what.  I have a general idea, but anything you can add will be most appreciated.

Physical things you spot will save us a huge amount of time--anything we might do wrong that cannot be compensated for by tuning.  Like for instance if the ground wire length must be a multiple of some factor.  Or you must see an orange spark on the antenna, not white.  This kind of stuff is priceless information.
