VIC setup 2
« on: January 01, 2012, 12:29:48 pm »
I got this core that I plan to use for the VIC. This is a big core , one of the largest they have from Ferroxcube. Hope specs will be close to the specs provided by dynadon.

yesterday I wound this thing with 30awg (0.25mm) wire
625 turns for primary
3500 turns for secondary + centertap @ 1750turns(center)
3500 turns for L1 and L2 chokes (also tapped L2 @ 3303 turns [ratio 12th root of 2]
extra auxilary coil with 1500turns

As for the resistance and inductance values for each coil, this is what I came up with:

primary:      10.98H 25ohms
secondary:   28.5H 192ohms
chokes:        aprox 28H 172ohms (each)

for me these look quite high values when compared to Stans. Maybe because of the flatter core he used resulting in less inductance and resistance.

Hydrogen mask,

I think your values are very big, try using a gap on the core... next time try winding all coils in the same bobbin, one over the other... this maximize the coupling (less turns needed)... be careful, this high voltage is very dangerous... in your design you will see a lot of sparks if all goes well.

On one of your pictures i saw you use a 3C90 core, that has a very high permabillity and thus you get your high inductance values.
