Mutual Inductance Measurement and Analysis of Near-Field Magnetic Coupling

Magnetic element is an important component of power converter. It includes inductors, common mode inductors and transformers. Configuration and wiring of their components will affect the ability to suppress electromagnetic interference noise. Due to the miniaturization and increasingly higher power density, the composition of the power converters become more and more compact, which leads to the near field coupling effects among the components. In this 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 the simulation through experiments.
