Differential mode and common mode inductor

Differential mode and common mode inductors     Differential mode signals and common mode signals Electrical equipment power lines and communication lines, at least two wires, the two wires as a round-trip line to transport power or signals, in addition to these two wires usually have a third conductor, which is the "ground". Voltage and current changes through the wire transmission has two forms, one is the two wires as a round-trip line transmission, we call it "differential mode"; The other is two wires to do the way, the ground wire to do the return transmission, we call it "common mode". Differential mode interference and common mode interference Common-mode interference refers to the non-useful electrical signal transmitted between the wire and the ground (housing), which is asymmetric interference, defined as an unwanted potential difference between any current-carrying conductor and the reference ground. The current magnitude of common-mode interference is not n…
