Abstract

This paper introduces a dynamic cosimulation approach to evaluate the effect of the selection of magnetic core material in toroidal inductors for DC-DC converters under varying load conditions. This cosimulation approach is based on the combination of transient analysis and finite element analysis to investigate how different high-frequency magnetic materials perform as potential core components for the converter’s inductor. The study considers a DC-DC buck converter modeled in Simulink and a detailed toroidal core inductor modeled through COMSOL Multiphysics. The LiveLink for Simulink tool available in COMSOL Multiphysics is utilized for accurate inclusion of the nonlinear inductor model and its integration into the dynamic buck converter model. The study provides insights into the behavior of different magnetic materials under high current exposure, and their suitability for use in DC-DC converters. The results of this investigation can provide practical guidance for designing and optimizing DC-DC converters in various electrical systems, with a focus on selecting appropriate magnetic materials for toroidal inductors.

DC-DC降压变换器暂态分析与电感设计的联合仿真方法

本文介绍了一种动态联合仿真方法，以评估在不同负载条件下，DC-DC变换器环形电感磁芯材料选择的影响。这种联合仿真方法是基于瞬态分析和有限元分析相结合的方法，研究不同的高频磁性材料作为变换器电感器的潜在核心元件的性能。该研究考虑了在Simulink中建模的DC-DC降压变换器和通过COMSOL Multiphysics建模的详细环形磁芯电感器。利用COMSOL Multiphysics中提供的LiveLink for Simulink工具精确地包含非线性电感模型并将其集成到动态降压变换器模型中。该研究提供了不同磁性材料在高电流暴露下的行为的见解，以及它们在DC-DC转换器中使用的适用性。该研究结果可为各种电气系统中DC-DC变换器的设计和优化提供实用指导，重点是为环形电感选择合适的磁性材料。

期刊介绍： COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
