Hi Amund This sounds like a very interesting problem. Likely many people will have advice. Maybe get lucky and someone will have had this exact same problem. I'd like to help if I can. Do you have more information on the failure? What test standard and test method did you use? How much over

A 3-phase product has three internal AC driven devices. The product fails on Conducted emission. When connecting AC filters to each internal AC driven devices, the emission gets even worse. Any clue about this phenomena? Is it some kind of impedance mismatch which derate the filters
