I have questions regarding how these values are determined.
Lp, Cp, are easily measured using any number of techniques. But what
about Ls or Cs?
Does Ls represent the "lumped' inductance of the secondary, measured (as
above) between the base and top toroid? I would bet this is the case
but an not 100% sure.
But the really tricky one is Cs. The only way I can see to determine
this is by measuring the actual self resonant frequency of the secondary
and toroid using a sig gen, 'scope and all that. Then - you compute Cs
via the frequency and Ls.
Any hints? How are you folks determining these values?
