High current common mode choke

Common mode inductors, also called common mode chokes, are often used in computer switching power supplies to filter common mode electromagnetic interference signals. In board design, common mode inductors also play the role of EMI filtering, which is used to suppress the electromagnetic waves generated by high-speed signal lines from radiating outward.

The motherboard inside the computer is a mixture of various high-frequency circuits, digital circuits and analog circuits. When they work, they will generate a large amount of high-frequency electromagnetic waves that interfere with each other. This is EMI. EMI can also be emitted outward through the motherboard wiring or external cables, causing electromagnetic radiation pollution and affecting the normal operation of other electronic equipment.

The chip on the PC board is both an electromagnetic interference object and an electromagnetic interference source during operation. Generally speaking, we can divide these electromagnetic interferences into two categories: series mode interference (differential mode interference) and common mode interference (ground interference).

The common-mode inductor is essentially a two-way filter: on the one hand, it filters out the common-mode electromagnetic interference on the signal line; on the other hand, it suppresses the electromagnetic interference it emits to the outside, so as not to affect the normal operation of other electronic equipment in the same electromagnetic environment .
