Simulation Analysis of Inductive Coupling and Capacitive Coupling between Cables

Due to the frequent occurrence of EMC problems caused by cables, considering the complexity and diversity of the electromagnetic environment of the intercity train, this paper analyzes the coupling mechanism of cable crosstalk and studies the coupling law between cables in different electromagnetic environments. Through the simulation software, the proximal coupling coefficients of the sensitive circuit under different load conditions are obtained, and the mechanism and law of the two coupling conditions are obtained, which provides a basis for restraining the cable coupling.
