am new here and already seeking for help.
Found this forum thanks to my schoolmates. Hope to get some answers and in the future also help to find some solutions.
Your circuit seems to be wrong.
Because you feed your inductance with rectified signal, there will be a DC (component) in the inductor voltage.
This generates high DC currents, and thus saturation of your inductance core.
Your calculations are for pure sinusoidal AC voltage without DC across the inductance.
This is not the case here...
this common mode filter will not (significantely) reduce voltage ripple in your output capacitor.
It is more a filter to be high impedance for HF to the right side circuit referenced to the left side circuit.
--> To reduce ripple in the right side capactior you need a (one or two) non coupled inductors.
