   This comes from a hamm radio point of view.

Has anyone here that is hands on considered that you need to
have an impedance match from input to output to get the most
power to the load?  I know from experience that if the match is
not close to perfect, the finals will load up with harmonics and
blow. Old tube sets could deal with it better but after a while,
the tube would gas out and short and then turn a nice purple.

Food for thought.

not really from a ham radio view; but from experimental view; it worked better if the coils were closer to the same inductance... didn't have a cap on the secondary, just LED load to control voltage and eventually an incandescent in parallel.

Hi MagPWR

In post #4656?
and this circuit is adjutable by frequency and duty cycle?

regards zcsaba77

Hi zcsaba77,
It is frequency and duty cycle adjustable.
I used 2n2f but you can use any value.

   Itsu:
   Good to see you here.
   I'm using the 0.22 to 0.47uf poly caps, 400 to 1600 volts on my Mazilli circuit.
They do not get hot, at all, although my fets IRFP260N which should be able handle the voltage and amperage , could boil water for my morning coffee.
   
  I wonder what Geo thinks of that simplified circuit that MenofFather posted, and did also make several changes to it.  Will it self run, still, as posted???

Hi Nick,

You are disadvantaged by not seeing the waveform at the gate of your mosfets. They are very likely being under driven as a result of the poor condition of your supply battery. You will not progress until you address this problem.

I think Geo is still lurking in the background, hopefully preparing a video to show some evidence that he has a self-runner.

Thanks all for your comments, i guess its due to the "equivalent series resistance" (ESR) of the used capacitors that some can get hot.
In a parallel tank circuit in resonance allthough if looking from the outside the thing should present itselve as pure resistive, but in the
both legs (inductor and capacitor) the currents can be very high causing heat losses due to their ESR.

Paralleling severall low value caps looks like a solution to try.


NickZ,

still going strong he, great.

well, as i showed before, your system works in 2 modes, and the mode which makes the noise (squeel) and produces the most output also
shows very irregular signals (peaks).

See below video at 4:55 mark for this irregular mode compared to the "normal" mode shown earlier around 4.20.

It could very well be like you said (and Void) that your multimeter is not able to handle this irregular spiky HF signal.
Also we are dealing with many amps (see video), so this will cause the heating up of your MOSFETs.
