How common mode choke works
Web14 de mar. de 2024 · One of the advantages of these kinds of chokes is they will not be saturated by differential mode currents. For those coupled inductors, coupling factor k can be calculated from Eq. 1: k = M/√ (L1×L2) (Eq. 1) and common mode and differential mode inductances can be obtained from Eq. 2: LDM = 2× (L-M) and LCM = (L+M)/2 (Eq.
