Constant-Flux Magnetics for Power Conversion

研究目的和方法：本研究的目的是确定具有常数的磁几何形状。磁通的分布，并演示磁元件的能量密度比现有技术高30%-50%。该方法分为三个任务：恒磁几何的综合、电磁建模和更广泛的影响。基于综合因素对多绕组电感进行识别，并通过有限元仿真进行验证。实际过程将被确定为选定的几何形状的制造。将为性能指标开发面向设计的模型。智力优势：至少30%的商用电感不存储或可忽略的能量。持续的流动?概念通过在可用的体积中填充尽可能多的磁（芯）材料来提高能量密度，然后分散绕组以形成磁通量的分布，例如，均匀地分布磁通量。将从结构和领域的角度制定指导原则，以实现恒定通量的概念。性能指标，如电感、电容和质量因子将被建模、量化，并与相应的基准进行比较。更广泛的影响：将为参加名为C-Tech2（计算机与技术和弗吉尼亚理工大学）夏令营的初高中女生开发演示模块，以发展和维持学生。对工程和科学有兴趣。通过一个名为“科学工程”的跨学科项目，将选择二年级和三年级的科学家来执行部分研究计划。将邀请行业导师帮助建立商业化之路。

Research Objectives and Approaches:The objective of this research is to identify magnetic geometries with ?constant? distribution of magnetic flux, and to demonstrate magnetic components with energy density 30%-50% higher than state of the art. The approach is organized into three tasks: Synthesis of Constant-Flux Magnetic Geometries, Electro-Magnetic Modeling, and Broader Impact. Inductors with multiple windings will be identified based on synthesis factors, and verified by finite-element simulation. Practical processes will be identified for manufacturing of the selected geometries. Design-oriented models will be developed for performance metrics.Intellectual Merit:At least 30% of the volume in commercial inductors stores no or negligible energy. The ?constant-flux? concept improves energy density by filling the available volume with as much magnetic (core) materials as practically feasible, then dispersing the windings to shape the distribution of magnetic flux, e.g., to distribute magnetic flux uniformly. Guiding principles will be developed from the structural and field standpoints to realize the constant-flux concept. Performance metrics, such as inductances, capacitances, and quality factor will be modeled, quantified, and compared with the corresponding benchmarks. Broader Impact:Demo modules will be developed for rising junior and senior high-school girls who participate in a summer camp called C-Tech2 (Computer and Technology and Virginia Tech) to develop and sustain the students? interest in engineering and sciences. Through an interdisciplinary program called Scieneering, sophomore and junior Scieneers will be selected to execute part of the research plan. Industry mentors will be invited to help establishing a path to commercialization.
