Hello,
We are workingon aa design that has a DC/DC converter that converts 120V AC to 12V DC with 12x8 VA power.
We fail the class A in Conducted Emission IEC EMC requirments, we are looking for a consultant to help us.
You forgot to attach your schematic so we don't have a clue about how it works.
It might be a switching converter that radiates harmonics or sends harmonics into the 120VAC power line.
Frequently the power cord has a hinged ferrite core attached which forms a filter without cutting the cord.
