A common mode inductor and an application of the common mode inductor to solve the conducted interference of the switching power supply

This utility model discloses a common mode inductor, including a magnetic core component and a first winding and a second winding wound on the magnetic core component. The number of turns of the first winding is not the same as the number of turns of the second winding. The design is specially treated for the common mode inductor, with different turns on both sides, and the magnetic cores should leave some gaps between them. It is not necessary to wind too tightly, so that the two inductors are unbalanced, which has a relatively large leakage inductance, so that the entire component has both the function of the common mode inductor and a large difference mode inductor.
