I have 65W flyback transformer , output 20V PO=65W the output has common mode noise, I did try many different common mode filter but still noisy, how can I do simulate for this noise to be able to fix this problem

Common-mode noise in a switcher often comes from stray capacitive coupling been the switching elements, such as the power transistor case and transformer windings, to the ground plane or metal chassis.
