2D FEM Modeling Comparison of Multi-Winding Magnetic Couplers for Power Electronics Applications
Year: 2025
Type: conference-paper
Abstract: Multiple-Active Bridge (MAB) converters, an extension of Dual-Active Bridge (DAB) converters, have emerged as a promising approach for multi-source, multi-load energy exchanges. A critical factor in their performance is the design of the multi-windings magnetic coupler, which determines the equivalent inductances and consequently the power flow between ports. This paper presents 2D FEM modeling techniques for multi-windings magnetic couplers, comparing various geometries models to balance precision and speed. The air gap-free FEM geometry reduces simulation time while maintaining accuracy, whereas the two stretched models involve a trade-off between precision on electrical model parameters.
