Hello Wattsup,

about power balance as you have sayd it's not so easy as:

- thinghs change as soon as you move a bit one of the freqs,
- thinghs change if you vary the input pulses duty cycles,
- thinghs change if you vary DC amplitude to mosfets,
- thinghs change if you vary mosfet driver amplitude & shape,
- etc, etc

(note: all is actually more difficult as if you change a parameter...may be all the other are as well affected..)

So what I can tell safely is that the impression is, given to have all the above points optimized  (..it's not so...), that the power on light is still less than that provided by the PS (but not far as in ECD case) ........remember that now about half of PS power goes anyway to mosfet's heat-sinks rather than on coils.......

Please take note that a full documentation on '2nd session test - full' will be shortly available on YouTube: don't miss it! There you will find many hints on PS voltage effect: you will see that it's unlinear.

So major efforts is now in optimizing the mosfet circuitry in order to firstly decrease the energy losses...than the synchronism implications raised by Wattsup may be well worth a try!

"Pulsing VDC to power Mosfet" : GOOD: I've to think how?

Any ulterior suggestion are really wellcame.

DO IT GUYS!!!!!!!    don't loose your precious time with     zfdsytebnrfh!fdkgrlg jhfhgf

I have one suggestion; I'm sure it's been said before, but it doesn't hurt to mention it again:
Use a battery, not a power supply!  That way you can be sure that there are no odd signals coupling back into your power supply and increasing power output without your knowledge.  I do this all the time; I've got a large 12V battery I keep on my bench for these kinds of experiments.

Got TUBES? GAWD!!! thats a stash!

*Again think that about half of the dissipated power vanish in heathing the power Mosfet's Heat-sinks...even"

If the heat-sinks are inside into the coil you can have this effect:
