Chinese Oscillator and MOS FET Driver, Hardware experiment

[synchro1]

Fantastic build! Can you spot the tiny cap in this photo? Just maybe you could squeak a few extra volts out of it with a small adjustment advantage there? 1300 watts is awesome. It would take a 2 horsepower gasoline motor to generate that kind of power!

The two horizontal small caps are in the primary side. 0,47uF each. Total c=94nF
The big one which stands vertical is the 8000V/22nF and it resonates in series with the 28T and the output trans.

ps. guys i have to go at work. See u later

The addition of a high voltage trimmer capacitor in parralell with the 8000V capacitor would allow for finer tuning to higher "Q" and consequently higher voltage. Results are already awesome!

I bet the Chinese inventor burned a trimmer cap out fishing for high "Q" then replaced it with the two additional 0.47uf resonators. You may need to start over to find the correct combination.

Merely a few centimeters difference in coil wire length can offset the LC "Q" enough to reqire an adjustment in the picofarad range. Fine tuning can double the tank voltage!

This is like getting real power from VARS. Phase angle Voodoo? I wonder if power would rise to meet the load if you put the reciprocal saw to work?

JLN boiled water with a hot plate sheerly with induction between two bifilar pancake coils with no wire connection between the primary and the output coil. The Chinese invention uses 4 coils with induction between the primary and the output coils too.

I think the ground is acting as an antenna and the power is broadcast. Stiffler's Slayer Tesla coil will illuminate LEDS from the ground like Lidmotor demonstrated. The power is probably running the saw backwards.
