The difference between common and differential mode inductor

The difference between common mode inductor and differential mode inductor Two types of inductors used to resist electromagnetic interference: common mode inductors and differential mode inductors. The disturbance electromagnetic field produces differential mode current between the line and the line, which causes interference on the load, which is differential mode interference. The disturbance electromagnetic field produces a common mode current between the line and the ground, and the common mode current produces a differential mode voltage on the load, causing interference, which is the common mode ground loop interference. The filter inductor that suppresses common mode interference is called common mode inductor. The filter inductance to suppress differential mode interference is called differential mode inductance. Common-mode inductors are two groups of coils with the same number of turns, the same wire diameter, and the opposite direction around the same core. A different…
