Kapanadze Cousin - DALLY FREE ENERGY

[itsu]

TK,

i did ask that same question then myself here:
http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg475064/#msg475064

But for my understanding, your grey area is not really our problem, the problem is the light blue area where the MOSFET is already on while its gate is off.
Do i understand correctly that the fact that yellow MOSFET is on (light blue area) is caused by the grey area effect caused by the other MOSFET?

Again, for an answer, you need to follow that discussion, i was happy with the answer provided by verpies in this specific push / pull situation.

That's as may be.... I can perhaps understand how the Drain voltage or current could _lag behind_ the Gate signal, but how in the world does any mosfet know to turn ON _before_ the gate signal rises above the threshold voltage? Is it predicting the future?
Drain voltage -- that is, the voltage drop across the Drain-Source -- goes low when the Gate charge has risen to and goes above the Miller plateau. The scopeshot above shows the Drain voltage going low well _before_ the Gate charge even begins to rise. How can this be?

Hi in this thread any thing is possible, and it's not like Verpies to make an error, but you can get another type of MosFet a depletion mode http://www.aldinc.com/pdf/IntroDepletionModeMOSFET.pdf
try playing with them  

On the other hand is the other Fet doing a OR gate thing trough the center tap winding ?

May pushpull transistors also not hot on resonance or on small current without snubbers. Or maybe your transistors is fake from aliexpess maybe?

  How about at resonance with a higher current and several hundred watt loads?
  The FETs stay cool with no snubbers on??? 
   Maybe you can make a short video also showing the bulbs being lit up, and some scope shots.

   I'm interested in using no snubbers also, but, I still don't understand how Stalker can do so, while showing drain voltages over 250v, at 41to 45% duty cycle. And wth NO snubbers on. How does he do it?

Absolutely stunning !Explain how you were able to have puresharp square wave input to mosfet gate when the output is loaded ! This is very important.
