Hi everybody,

Can someone help me with a circuit that can sync the interrupter on the AC mains? this will be for my Semi QCW SSTC. (Stacato)
To accomplish sword like sparks, the ramp of my AC(60hz) should be sync with the interrupter... the problem is i dont know how. Any idea for the circuit? thanks.

Well usually you can leave the gate driver running all the time, if it can cope with the heat generation. Maybe you wanted "pulse skipping" like it is done with VTTCs? Then you can try this circuit and modify it, or add a monostable circuit to it. Link2

Thank you for sharing these very informative circuits., On my first look, it seems that they are 'identical' in some way.. I'll try this circuit later this evening thanks again,
