I tried doing a search to no avail, and have been searching any and all media for an answer to what must be a simple question since everyone seems to understand but me.
The circuit I am trying to build requires a power source for the 555, and a secondary source to drive the flyback primary with much more power than the timer can handle. I have built ZVS drivers, 555 drivers, 2n3055 drivers, you name it. I even have a wonderful resonant MOT setup. For the life of me, however, I don't seem to grasp how exactly the second supply is to be wired in. It seems you disconnect the primary from the 555 positive supply, and connect it to the second power source, but I have found no details on it. Where does the negative of the primary supply go? it shows ground, but I have had no success with this. It simply tries to destroy my variac at anything over 12v. From what I can tell, the positive from PS2 goes to the primary and resonant cap, to the the drain and ground, and source goes to ground and in some schematics has a couple caps and a diode on ground side, but I must be wiring it wrong because its simply not working whatsoever, If I omit a second source and limit it relative to the 555 it works, but only just barely, not reaching anywhere near the ZVS levels of power. I'm trying to build a plasma speaker using this, but I can't seem to figure it out and have found no information or anyone willing to even reply to my requests.
Can anyone here help me understand what I'm doing wrong? I'm working mainly off the schematic provided by Jozef Bogin, the "moster 555 flyback driver", but when he mentions the second supply he says to just "disconnect the primary from the 12v rail", which is exactly zero help at all.
