Common mode current is the portion of conductor currents that are unmatched with the exactly opposite and equal magnitude currents.[1] Common mode current cause multiconductors to act or behave like a single conductor. In electromagnetic compatibility (EMC), there are two common terms that will be found in many electromagnetic interference discussions or considered as fundamental concepts, those are Differential Mode and Common Mode. Those terms are related to coupling mechanisms. Many electrical systems contain elements that are capable to act like an antenna. Each element is capable of unintentionally emitting Radio Frequency energy through electric, magnetic, and electromagnetic means.[2] Common Mode coupling as well as Differential Mode coupling can occur in both a conducted and radiated way.[3]
