Homemade Flyback secondary -2-By Radu Motisan Posted on April 17th, 2010 , 978 Views (Rate 0.87) |
I've been keeping this nice big ferrite core in my toolbox:
Now I've decided to try to construct a more robust flyback secondary, using the experience from the previous setup that you can see here.
For the insulator I've used Green House foil:
The windings are very close and tight, aprox. 60 turns per layer. The ending wire is insulated and brought back to the start side before a new layer is constructed. Also oil is added over the turns to fill some of the air gaps:

I've wired arround 7 layers for a total of aprox. 400 turns. To test the flyback I've used my high power ZVS driver (with a 6.6uF/630V capacitor):
I'll need some extra turns for higher voltage, but the current is good. I've used 0.4mm CuEm wire.

Вот у меня вопрос, яндекс по количеству комментов говорит что оценивает в рейтинге, интересно так это или нет, по этому я пока на всякий случае такие г.комменты осталяю

What oil did you use?
