What is differential mode inductance？
The concept of differential mode inductance is proposed
In actual work, there are often engineers who will mention differential mode inductance, and often make new people who have not long entered the line confused, so what is differential mode inductance? As we all know, inductors are able to convert electrical energy into magnetic energy storage components, in the circuit mainly plays the role of filtering, oscillation, delay, choke, etc., and screen signals, filter noise, stabilize current and inhibit electromagnetic wave interference. We are familiar with common mode inductance is used to suppress common mode interference, corresponding to this, used to suppress differential mode interference is differential mode inductance.
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".
Conclusion
Differential mode inductors are not mysterious, in fact, we often use power inductors.
