bipolar coil design



Original poster: Lee Kohlman <lwkksw@xxxxxxxxx>

I'm new to the list and have been collecting information and parts to build a tesla coil.
I am planning to build a bipolar coil.


My current specs are looking like this:

Secondary- 20 Awg wound 56" on a 6.25" pvc form, approx 1700 turns
Primary- 6 turns .25" copper tube flat spiral 4.5" id, 8" od at center of secondary
Hv Supply- 2x 15kV 60mA NST (parallel)
Cap- .03uF 45kV pulse capacitor
Topload- 2x 6" aluminum dryer duct 30" diameter toroid, 1 on each end 4" from secondary windings.


Secondary frequency- 112.76kHz
Primary- 232.96 kHz

I used javatc to do the calculations. If you want to see the complete output let me know.

Any ideas?

Thanks,
Lee K.
