When you said about the coils having capacitance and effects resonance,
the total capacitance Ct=(CpSec + CpChoke1 + CpChoke2 +Cwfc) is close to the smallest capacitance in the total series circuit?
This Ct and the Lt is the resonance frequency the VIC will resonate? Should Cp be in the nano or pico farad?
The capacitance of my choke is greater than my wfc's capacitance.So it has more effect on the resonance frequency.Only the positive choke is effecting the resonance frequency.The negative choke doesn't change it.
Choke capacitance could be in the uF range or larger.Measure yours and see what you get.It's a factor of the number of turns you have on you chokes windings.A coil with mulitiple row of turns has a greater effect on it's capacitance,than a single row of turns.What I mean is,lets say you have a single row of turns that measures 10 uF.Now lets put two rows of turns on that same bobbin that has twice the number of turns as the first.Will you have twice the capacitance? NO! Why?
Because the capacitance is between the wires insulation,and now with two rows ,you get the wires acting on the ones besides each other as well as the ones on top of each one.The capacitance grows fast with multi layers.
The gap of your cell is fine.Measuring a cell's capacitance is not easy,and I'm not sure whats the best way to do it.I use a B&K Precision meter that cost $300.And I'm not sure if it is even right.
What are you using,or are you just calculating?The later I don't think will work either.
