Inductors, common-mode inductors, transformers and other magnetic components are important components of power converters. Their layout and wiring may affect the ability to suppress EMI noise. As a result of miniaturization and higher power density, the composition of power converter becomes more and more compact, which leads to the near-field coupling effect between components. In our study, the mechanism of near-field magnetic coupling between magnetic elements is analyzed, and the accuracy of the parameters of near-field magnetic coupling is further verified by experiments.
