Electrical power converters are critical to a wide range of applications from renewable integration to transportation electrification and can be a key factor in determining the size, weight, and efficiency of all types of energy conversion systems. Magnetic components are typically the largest and least efficient components in power electronics. While there have been major strides in the development of wide-bandgap (WBG) semiconductor devices and circuit topologies, the necessary advances in the modeling and design of complex power magnetic components are lagging. This project will conduct fundamental research on the magnetics modeling theory for linear and non-linear micro- and macro-scale behavior analysis of power magnetics. The linear electromagnetic field and current distribution in windings, and the non-linear hysteresis of power magnetic core materials will be modeled under a unified framework, targeting sophisticated magnetic structures with matrix coupled flux and non-uniform flux distribution. Methods will be developed to characterize the complex behavior of electromagnetic hysteresis in the magnetic materials and model the way they impact the field and current distribution in magnetic components. The outcomes of this project include 1) a systematic method for modeling and designing complex multi-winding power magnetics; 2) a family of software tools for optimal design of power magnetics; and 3) a group of design examples to demonstrate and validate the effectiveness of the new modeling approach. These outcomes will make the magnetic components in future electric vehicles, computers, renewable energy systems more compact, more efficient, and be able to perform more sophisticated functions. With the theories and methodologies developed in this project, sophisticated magnetic components can be designed and simulated with high accuracy, and fully unlock the potential of WBG devices. This will increase energy efficiency, reduce emissions, and create new societal opportunities. We will work to ensure this outcome by disseminating the results in education, research, and commercialization. There will be impact on research experiences and training of engineering students. Research will be conducted by both undergraduate and graduate students, strengthening their skills in this important area, with participation of under-represented groups especially encouraged. The outcomes of this research will be embedded into the MagNet Project – an international open-source magnetics community effort.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

电力转换器对于从可再生能源集成到交通电气化的广泛应用至关重要，并且可以成为决定所有类型的能量转换系统的尺寸，重量和效率的关键因素。磁性元件通常是电力电子中最大和效率最低的元件。虽然宽带隙（WBG）半导体器件和电路拓扑的发展取得了重大进展，但复杂功率磁性元件的建模和设计方面的必要进展却很滞后。本计画将针对电力磁性元件之线性与非线性微观与宏观行为分析之磁性元件模型理论进行基础研究。绕组中的线性电磁场和电流分布以及功率磁芯材料的非线性磁滞将在统一的框架下建模，针对具有矩阵耦合磁通和非均匀磁通分布的复杂磁结构。将开发方法来表征磁性材料中电磁磁滞的复杂行为，并对它们影响磁性部件中的场和电流分布的方式进行建模。该项目的成果包括：1）复杂多绕组功率磁体建模和设计的系统方法; 2）功率磁体优化设计的软件工具系列; 3）一组设计实例，以展示和验证新建模方法的有效性。这些成果将使未来电动汽车、计算机、可再生能源系统中的磁性元件更紧凑、更高效，并能够执行更复杂的功能。利用本项目开发的理论和方法，可以高精度地设计和模拟复杂的磁性元件，并充分释放WBG器件的潜力。这将提高能源效率，减少排放，并创造新的社会机会。我们将通过在教育、研究和商业化方面传播成果，努力确保这一结果。这将对工程专业学生的研究经验和培训产生影响。研究将由本科生和研究生进行，加强他们在这一重要领域的技能，特别鼓励代表性不足的群体参与。这项研究的成果将被嵌入到MagNet项目-一个国际开源磁学社区的努力。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
