Before putting the PLL on a PCB i wanted to test it with the yoke / MOSFETs.

I connected it to the yoke, driving the inductor coil after putting the inductor / 3-turn coil / Wima caps combo to 15Khz resonance.   
It turned out that i needed 2x 0.47uF and 2x 0.15uF parallel = 1.24uF to reach a (series)resonance of 15.4KHz.

The grenade is only loaded with a 40W/240V bulb and not connected to the 28 turn yoke secondary.

Input to the MOSFET's is 24V @5.7A via a PS, the PLL runs on a 12V battery.

Feedback from the toroid (T106-2, 30 turns awg 18) into the PLL.

We have high voltage (648V pp) and high current (75A pp) running in the inductor coil and it seems they are 90° out of phase (current leading)
like being shown in the diagram of post #10839  here:

See screenshot 1 where yellow is voltage across the inductor coil, and green the current through this coil (25A/div.)

Some temperature measurments show this coil getting hot fast.

Also my (old) snubber scheme is melting the link between the schottky and TVS i have across each drain.
Need to change to the new snubber setup.

Second screenshot is the signal on the drains of the MOSFET's.

  I think that there may be more to it, than just providing for the 130v, with no real current behind it, just fluffy voltage. Or not? We'll see.... but, it looks to me like the Kacher coils may also need a couple of amps, to be effective, as well as the right frequency.

Off course, when measuring across a coil in a LC series combination will always show the voltage and current 90° out of phase, even when in resonance.
I should have measured across the complete LC series combination to obtain a 0° (in phase) relation of voltage and current when in resonance.

Doing this (so basically measuring across the 3-turn coil) shows the combined square wave signals from the MOSFETs, but as can be seen in the screenshot below here
the voltage (yellow) and current (green) are in phase (at resonance).

Hi Nick, looks good. Just i would move the measuring devices a bit away from the HV coil

 
   John.K:  Thanks,  and yes, you're right, but I have very limited real estate on the kitchen table, and am only allowed 1/2 meter square of space, by my wife.  I'll move the Kacher as far as possible, but it has been working ok at even that distance.
In any case, I know what you mean.

Hi
good Job...
Itsu/
could use a measurement of the high amplitude resonance, and what will change when you increase the load Change the bulb with a 200 Watt.
and compare?

As in Thebes will be supported this arrangement Feedback from the toroid

or actually maintains a high current under load changes and, if the output frequency changes grenade on the bulb
such benchmark as did Ruslan 100W+80W the frequency drops 21Khz/27Khzhim but claimed that the resonance is

and one more thing as you now have 5.7 Ampere at 40 W. how many drops  Amp on PSU as you connect the 200Watt ?
on what shows without switching circuit winding 28
Thanks.
