Patent ID: 11362632

Abstract:
A high-capacity common-mode inductor processing circuit for network signal is disclosed. Each of high-capacity common-mode inductors is disposed between two adjacent circuit channels to perform signal coupling, and each high-capacity common-mode inductor has parasitic capacitance between primary and secondary sides thereof, each of autotransformers is disposed on a side of corresponding one of the high-capacity common-mode inductors, and center tap lines of the autotransformers are grounded. The high-capacity common-mode inductor includes an iron core post and an iron core cover, the iron core post includes a winding part to be wound by conductive wires, and the conductive wires are wound on the winding part by a preset number of turns, and upwardly stacked and wound on the winding part by a preset layer number. The high-capacity common-mode inductors and the parasitic capacitances can eliminate noise on the circuit channels and perform signal coupling.
