If you would need to build 24/7 working SSTC which way would you go ?
For such situations in museum I always build SGTC-s and they perform forever reliable. But now they insist on SSTC with 8-10 inch sparks.
Im not sure which way to go, and this is what i made until now:
Secondary
4.5 " diameter
Legth 7.5 " (5" winding, 1" free down and 1.5" free up)
1150 turns of 38 AWG
FRES ~222 KHz
Topload 8 inch sphere
FRES with topload ~96 KHz
Primary
Lexan pipe, 1 cm bigger than secondary
25 turns of 1.5 mm AWG 17
Bridge:
Fullbridge :
4XIRFP460
15 V zeners
10 Ohm resistors on gate
MUR460 diodes
Massive heatsing with fan
And now im not sure with what to drive it?
TL494 is out of question (Richies design)
Steve MINI SSTC seems the best way to go
Steve PLL - not sure, never worked fine for me
