High-Power common-mode inductance T1515 Vertical flat wire
Product performance:
The common mode inductor is essentially a two-way filter: on the
one hand, it needs to filter out the common mode electromagnetic
interference on the signal line, and on the other hand, it must
suppress itself from emitting electromagnetic interference, so as
to avoid affecting the normal operation of other electronic devices
in the same electromagnetic environment.
For the ideal inductor model, when the coil is wound, all the
magnetic flux is concentrated in the center of the coil. However,
under normal circumstances, the toroidal coil will not be fully
wound, or the winding is not tightly wound, which will cause
leakage of magnetic flux. Common mode inductors have two windings
with a considerable gap between them, which creates flux leakage
and creates differential mode inductors. Therefore, common mode
inductors generally also have a certain ability to attenuate
differential mode interference.
In filter design, we can also take advantage of leakage inductance.
For example, in an ordinary filter, only one common mode inductor
is installed, and the leakage inductance of the common mode
inductor is used to generate an appropriate amount of differential
mode inductance, which can suppress the differential mode current.
Sometimes, it is necessary to artificially increase the leakage
inductance of the common mode choke coil and increase the
differential mode inductance to achieve a better filtering effect.
