I have completed the circuit, and is ready to be tested.

I will still test different mosfet drivers.

The pot in the center acts like a voltage limiter from 5v and up, when i go above 5v the 2e tl494 goes of, but if i turn the center pot then the 2tl494 goes on again but goes off by 6v etc etc.

The duty cycle of the 2e tl494 doesnt go higher then 37% and max frequency is about 336kHz but i will have to play with that some more.

The 1e tl494 acts like the oscilator, and the 2e as a solid state tesla or inverter circuit.

For mosfet driver i used the bc557b (tr1) transistor and the mosfet for now the irf3205

I have noticed that when 2 harmonics from both tl494 come close to each other they automaticly attract and melt together and turn into 1 big harmonic, its like a lock on when they come close together.

Sofare no noises from the core, and the led stays longer on when closing the switch but that is because the cap C1 helps out.

But the circuit is ready to be tested to the fullest, i have added resistor R9 ( 4.7k ) from vcc of the 2e tl494 and going to ground, and R8 ( 82 ) ohm comming from pin 16 going to ground.

Instead of the SF56 i used the HFA08TB60 cause i use that in my ACMMJB to capture extra energy going to my 2e ouput of my ACMMJB

Once all is working as i want it, i will solder everything to a pcb

I will also update the circuit drawing,


Thats it for now!

Thnx Dexor!, Disturb anytime! :p

@JB,

Nice work! Keep us up to date on this I would be very interested!

All the Best

P.S: My circuit draws way too much current to be powered, I should say started from a 9 Volt Battery that's why I started to look at the series resonant ideas that are incorporated.

Hello All,
I hope this helps.
