Hi i am maked half-bridge sstc wich making 35-30cm sparks (no cap, full-wave), so i decided to make it with interrrupter, because power is 1,5KW, and i believe it produce bigger sparks, I found a lot of interupter schemes with 555, dual 555 , Pll, ad others, wich is best ?? maybe that one?

I was very happy with my single 555 timer interrupter with only adjustable on and off times. For normal SSTC work (non DRSSTC) I think the most you would ever need is a dual 555 timer design as to include a burst mode (a couple of pulses from the first 555 timer).

I dont think there is "the best" interupter around. There are some that are better than others. It really depends on what you want the coil to do. If you are making a small SSTC, a 555 or hex inverter oscillator will do. For the big coils, you would want something more elaborate, such as the interupter will only interupt on the rising or falling edge of the transition of the next inverter step.
