Simulation Analysis of Near-Field Magnetic Coupling in Magnetic Elements

Abstract

Magnetic components are an important part of power conversion. The placement and wiring of their magnetic elements may affect their suppression of 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 paper, we describe the mechanism of near-field magnetic coupling among the magnetic components. The accuracy of near-field magnetic coupling parameters is further verified by HFSS simulation.
