4.Product Introduction

Common mode inductors, also known as common mode choke coils, are often used in computer switching power supplies to filter common mode electromagnetic interference signals. In the design of the board, the common mode inductance also plays the role of EMI filtering, which is used to suppress the electromagnetic wave generated by the high-speed signal line and radiate to the outside.
The filter circuit of the common mode inductor, La and Lb are the common mode inductor coils. The two coils are wound on the same core with the same number of turns and phases (winding reversed). In this way, when the normal current in the circuit flows through the common-mode inductance, the currents generate opposite magnetic fields in the inductive coils wound in the same phase and cancel each other out. At this time, the normal signal current is mainly affected by the coil resistance (and a small amount due to leakage). damping caused by inductance); when a common mode current flows through the coil, due to the same direction of the common mode current, a magnetic field in the same direction will be generated in the coil to increase the inductive reactance of the coil, so that the coil behaves as a high impedance, resulting in Strong damping effect, in order to attenuate the common mode current to achieve the purpose of filtering.
In fact, if one end of the filter circuit is connected to the interference source and the other end is connected to the interfered device, then La and C1, Lb and C2 form two sets of low-pass filters, which can make the common mode EMI signal on the line be controlled at a very low level. on the level. The circuit can not only suppress the incoming of external EMI signals, but also attenuate the EMI signals generated when the line works itself, which can effectively reduce the intensity of EMI interference.
