Hi,
The thing is that i want to wind a multi-tapped toroid inductor for the this circuit (see picture at the bottom)
Using an MPP core.
What i am confused about is this.
On the following table you can see that when the permeability of an MPP core increases
the high frequencies it can handle will decrease, is this correct?
This must have an impact on the Q factor as well, because i would need more wire on a lower perm core, so the overall resistance goes up.
What i know so far is..
To achieve best results, all tapped windings should be evenly distributed 360º around the core, and all taps should exit the core at nearly the same point.
And then we have reverse winding and double reverse winding techniques to limit capacitive losses?
must be the same as progressive winding i guess?
I would like to know if i can measure the capacitive losses with my LCR meter?
Is this simply measured like this:
Measuring capacitance from tap 1 to all the other taps?
I am pretty new to this, but i know how to calculate the turns i need and so on, but any tips or information on this would be appreciated a lot.
Kind regards.
