IUCRC Planning Grant NCSU: Center for Advanced Magnetics for Power and Energy Development (AMPED)

电气化的趋势正在推动对能够以前所未有的开关频率和功率水平组合运行的改进软磁材料的需求，以及对高功率密度但极其高效的工程组件的需求。这些趋势还通过电动汽车、混合动力飞机和分布式可再生能源等领域的预期增长，为美国国内创造了重大的新经济机会。拟议的先进磁学电力和能源开发中心(AMPED)的主要重点将是高功率磁学这一至关重要的领域，以及在这一应用类别中与现有和新兴电机拓扑和设计的接口的优化。作为一个国家和经济体，成功应对挑战和利用这些机遇需要跨越材料科学、应用物理和电气工程的跨学科技能，以及零部件(电机、变压器、电感等)最终用户之间的合作。以及材料和制造业。拟建的AMPED中心旨在满足对未来新一代跨学科劳动力的需求，这些劳动力已经准备好并渴望迎接广泛采用电气化和电力转换技术增长带来的新挑战。AMPED产品组合包括的主要研究领域包括：(1)新型磁性材料和宽禁带和超宽带隙半导体的制造，(2)先进电机设计概念，(3)磁性元件的新设计和优化技术，(4)宽禁带电力电子转换器与磁体之间的相互作用，(5)由下一代磁体实现和利用的先进电力电子转换器拓扑结构，例如多端口功率转换，以及(6)可调和可变磁体技术及其在高级功率转换方案中的应用。各机构已计划开展强有力的合作，各自拥有独特的能力：卡内基梅隆大学-非晶态和纳米晶磁材料及制造、北卡罗来纳州立大学基于宽禁带的半导体电力电子和高速电机控制与测试、匹兹堡大学铁氧体基软磁材料和电磁场辅助的先进制造、元件设计战略以及磁性/电力电子接口。NCSU将利用其在宽带(WBG)功率器件和电力电子应用领域长达30年的研究。NCSU在具有WBG设备[如固态变压器、高速电机驱动系统]的功率转换器的磁学要求和应用方面拥有丰富的经验，并在与CMU和UPIT合作使用新的磁性材料用于下一代功率转换系统方面拥有丰富的记录。拟建的中心占地8000平方米。英国《金融时报》中压实验室有12千伏和1兆瓦的容量，屋顶上有40千瓦的光伏。此外，还开发了一种最先进的基于功率转换器的磁学试验台，可自动测量磁芯、变压器和电感的特性。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Trends towards electrification are driving the needs for improved soft magnetic materials that can operate at unprecedented combinations of switching frequencies and power levels, as well as engineered components which are highly power dense yet extremely efficient. These trends are also creating major new economic opportunities for the domestic US, through anticipated growth in electric vehicles, hybrid-electric aircraft, and distributed renewable generation amongst others. The primary emphasis of the proposed Center for Advanced Magnetics for Power and Energy Development (AMPED) will be the critically important area of high-power magnetics and the optimization of interfaces with both established and emerging electrical machine topologies and designs within this application class. Successfully tackling challenges and exploiting these opportunities as a nation and an economy requires interdisciplinary skills spanning materials science, applied physics, and electrical engineering, as well as collaborations between end-users of components (motors, transformers, inductors, etc.) and the materials and manufacturing community. The proposed AMPED center seeks to address this need for a new generation of an interdisciplinary workforce of the future that is prepared and eager to take on the new challenges presented by widespread adoption of electrification and growth in electric power conversion technologies. Primary research thrust areas included within the AMPED portfolio include: (1) new magnetic materials and manufacturing for wide bandgap and ultra-wide bandgap semiconductors, (2) advanced electric machine design concepts, (3) new design and optimization techniques for magnetic components, (4) interactions between wide bandgap power electronics converters and magnetics, (5) advanced power electronics converter topologies enabled by and leveraging next generation magnetics, e.g., multiport power conversion, and (6) tunable and variable magnetics technologies and their applications in advanced power conversion schemes. Strong collaborations between sites are planned, with unique capabilities residing at each institution: Carnegie Mellon University - amorphous and nanocrystalline magnetic materials and manufacturing, North Carolina State University – wide bandgap-based semiconductor power electronics and high-speed motor controls and testing, University of Pittsburgh – ferrite based soft magnetic materials and electromagnetic field assisted advanced manufacturing, component design strategies, and magnetics / power electronics interfaces. NCSU will leverage its three decades of research in the area of Wide Band-Gap (WBG) power devices and power electronics applications. NCSU has significant experience in the magnetics requirements and applications for power converters with WBG devices [such as Solid State Transformer, High-Speed motor drive systems] and a track record of collaborating with CMU and UPitt on the use of new magnetic materials for the next generation of power conversion systems. The proposed Center has acces to 8000 sq. ft. MV lab with 12kV and 1 MVA capability and 40kW of PV on the roof. Additionally, a state-of-the-art power converter based magnetics testbed has been developed with automated measurements for the characteization of magnetic cores, transformers, and inductors.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.
