@all
I asked Wesley if he can talk or email Akula for the winds.
While you guys ponder the circuit (I told you guys not to make it yet....but boys will be boys - hehehe), I am preparing a Standard Procedure for OU Coil Winding.
Point is forget what Akula says about 15/45, it means nothing but a range of turns, so you don't make a coil with 100/400. The 15/45 is a 1:3 ratio. The only real fixed component is the E core. The primary and secondary must be wound as per the characteristics of both the wires used and the number of turns required to produce not more and not less of an impulse. My idea is if everyone followed a set procedure to make the primary and secondary winding, your coil will be well balanced regardless of the turns or core type since it will match your core limitations.
15 turns primary. So what if with only 11 turns you get the same or better output at 36% less impress cost plus 36% less mosfet killing flyback plus better core to wind sensitivity. What if 15 turns is saturating your core at only a half impulse and with that other half excess being over the core limit seizes the reactivity of the core. Some are saying their cores have cracked already. Wondering why?
I think it's about time that we started to work smarter on both sides of the pond. With such an OU based standard, our Russian friends or any builder can simply say "This transformer was wound using XXXXX standard except step 3 where I started at 2 turns". Then provide some core, wire specs and possible resonance frequencies as a guide to others. This way anyone in the world will be able to come very close to the same transformer build regardless of number of turns since the main builder used the same standard to wind his coils with which he obtained the results that others are looking to now replicate.
Many here have been around the block a few hundred times already and can attest to the fact that although all come on board with the best intentions, that is not enough. Good intentions are great but making sure your efforts are not unknowingly thwarted by actions based on a lack of foresight is worth gold to any such enterprise. What we want is not winding up again at page 345 by playing musical chairs.
One observation like;
1) @Grumage, your coil wire type seems to have its plastic outer coating to be very soft and in a transformer dishing out 30 watts, it will risk shorting in the center winds possible then making your drive circuit overheat and blow. So make sure the wire you are using has a good coating on it that will withstand some heat.
About the standards, if we can have a good 4-5 standards that cover a good range of building methods, then the actual information resulting from these should help everyone stay on the same page.
I am presently working on the LTPU/FTPU and will have some great discoveries to announce soon enough. But I will place the procedure in this thread and at my Understanding Overunity thread since this applies to everyone.
All the best.
