The common mode inductance has the same winding direction, and the magnetic flux of common mode current parameter cancels with each other. Therefore, magnetic materials with high permeability can be used to realize small volume and large sensitivity without saturation.The interference between two power lines on the ground is called common-mode interference. Then, there is no common-mode inductor manufacturer's ground wire on my power supply. How does this common-mode inductor work?The so-called common-mode current is the current flowing into or out of the LN line at the same time. The artificial LISN network is used when testing the conduction.
Common-mode inductor winding is the number of laps two same phase winding winding in the same magnetic core, the current produced by the reverse magnetic field offset each other, so will not result in a saturated, say as to what you see around to do not know whether the winding direction of said, if it is around the same side, then the two winding common-mode inductor is opposite in the direction of the factory system, a clockwise and counterclockwise, if it is different around the edges, that is is clockwise, so this problem is a little discrepancy, see what you mean, however, guarantee the same phase, with the number of turns.
The winding inductor is the miniaturization product of the traditional winding inductor, and the stacking inductor is made by the multi-layer printing technology and the stacking production technology, and the volume is smaller than the winding chip inductor.
Winding inductance: it is characterized by a wide range of inductance (mH~H), high inductance precision, small loss (i.e., large Q value), large allowable current, strong production process inheritance, simple, low cost;The downside is that further miniaturization is limited.Winding chip inductors with ceramic cores have a place in high-frequency circuits because they can maintain a stable inductance at such high frequencies and a fairly high Q value.
