Hi
I am making SSTC with 74HC14, i don't want to make antenna, because i want that everything will be in box, so CT is best solution :)
With CT is better ? more windings or 60 ?

You have to bound your question a bit better than that.

Kind of like asking what kind of vehicle do i need to transport my box.

Well, is your box a 1kg box, a box full of rocks weighing 1000kg, or a box holding 20 vehicles weighing well over 50000kg???

look, i have ~3000W 74HC14 controlled SSTC,i need that all electronics's should be in my sstc box, so i decided to use CT for secondary feedback, i try 60T CT, sstc work's good, but maybe with 120T CT will be better, so i asking which CT is better, ferrite core are same confused
SSTC parameters:
3000W full-bridge
primary 12T secondary up to 1200T
two modes:Full Wave no interrupter, no cap and Interrupting with 500uF cap
neutral

I doubt it makes a difference considering all it does is sense the current flow from TC gnd to Earth gnd and produce a P-PV so if you reduce the # of turns you increase the Voltage the CT puts out.

Wind the CT so its resonant at the frequency youre using. For me its about 200KHz and which is 60 turns for the cores I use. It works very well.
