high voltage

[raburgeson]

What would happen if I put an n fet on a flip-flop and drove 3 auto coils primaries in parallel and hooked the
minus of the first coils secondary to the secound coils secondary's plus. Then the secound coils minus to the
thirds plus. And if i used 35kvolt gm coils wouldn't the output between the plus on the first coil and the output
of the minus on the third coil show a potential difference of 105k volts? ? ?

Well.........after you separate the secondary ground from the primary ground (they are connected), I suggest you keep your pulses very very short and give it a rest inbetween those pulses if you want to keep the smoke inside.  (assuming you have a job for this daisy-chain to perform)  Personally I think the higher voltage will leak through the insulation on the latter one or two since you are exceeding the prescribed limits by leaps and bounds.  Having said that......go to the junk yard and give it a go.

Na, I'll cut the current to 0 tie them together with some 640kv caps I got, just use the center one to
gen a potential difference and make the 2 outside ones provide all the current. and if that don't work
I'll toast marshmellows on the coil that didn't make it.

>>Yes, you'd get 105 kilovolts VAC if all three secondaries were in series.  However, coronal discharge would be severe and then there's the factor of possible insulation breakdown between coil windings.

Suppose you have 4-5 transformers in series and used a lower voltage to drive the primaries?  The transformers would be less strained by higher voltage.  The average voltage for 4-5 secondaries would be higher, but coronal discharge would also be greater.
