Engineering Research Center for Power Optimization for Electro-Thermal Systems (POETS)

几乎所有的现代电子系统都遇到了功率密度墙，功率密度的进一步提高带来了重大挑战。NSF电热系统功率优化工程研究中心（POETS）旨在通过改变设计来增强或增加在严格受限的移动的环境中可用的电功率密度。正如最近的电动汽车和飞机电池火灾所说明的那样，高密度电力和热功率流的管理是安全关键的社会需求。在筒仓中进行的工程教育限制了系统级的设计和操作方法。POETS将创造人力资本，这些人力资本经过明确的培训，能够跨越技术学科的界限进行思考、沟通和创新。工程研究中心（ERC）将进行课程改革，以系统的观点进行跨学科的培训。它将开发教学工具，使更多的干一级的理解和传播这些整个本科课程。POETS将针对旨在早期保留的本科课程修改，并将其与本科研究和K-12教师活动相结合。POETS的研究将直接使其行业利益相关者受益，包括电力电子原始设备制造商（OEM）和OEM供应链中的中小型企业。一个行业/从业者咨询委员会将帮助直接努力向POETS研究发展的现成接受者提供帮助。POETS将利用生态系统的产出，推动研究跨越“死亡谷”走向商业化。POETS使用系统级分析工具来识别提高功率密度的障碍。设计工具将用于创建最佳的系统级和子系统级设计。新的算法工具将通过结构优化来解决集成电热问题的多物理性质。一旦确定了障碍，POETS将开发使能技术来克服这些障碍。这些系统的操作需要开发异构的决策工具，利用多个时间尺度层次结构，不适合实时使用。这些管理方法的实施需要超越当前2D设计的新3D电力电子架构。热管理将与新的3D电子系统设计紧密结合，采用电力电子，存储等拓扑优化新设计将紧密交织元素，如固态热开关和模块化多长度尺度元素;即散布器，存储单元，相变和质量流系统与对流单元相互作用。基础研究的进展将支持3D组件技术的发展。新材料系统将通过操纵纳米结构来开发，以提供可调的方向性，用于平面内和平面外的热功率流。这些将与基于新的传导/对流系统的微米和纳米级热路由相结合。由相变材料制成的缓冲器将被集成到这些系统中，以增加具有定向功率流致动的自主材料的类别。新的测试系统将整合系统知识，使技术和根本突破到模块化的演示。

Nearly all modern electronic systems are hitting a power density wall where further improvements in power density pose significant challenges. The NSF Engineering Research Center for Power Optimization for Electro-Thermal Systems (POETS), aims to enhance or increase the electric power density available in tightly constrained mobile environments by changing the design. The management of high-density electrical and thermal power flows is a safety-critical societal need as recent electrical vehicles and aircraft battery fires illustrate. Engineering education conducted in silos limits systems-level approaches to design and operation. POETS will create the human capital that is explicitly trained to think, communicate, and innovate across the boundaries of technical disciplines. The Engineering Research Center (ERC) will institute curricular reform to train across disciplines using a systems perspective. It will develop pedagogical tools that allow greater stems-level understanding and disseminate these throughout the undergraduate curriculum. POETS will target undergraduate curriculum modifications aimed at early retention and couple it with undergraduate research and K-12 teacher activities. POETS' research will directly benefit its industry stakeholders comprised of power electronics Original Equipment Manufacturers (OEM) and Small to Medium sized businesses in the OEM supply chain. An Industry/Practitioner Advisory Board will help direct efforts towards ready recipients of POETS research developments. POETS will harness the outputs of the ecosystem and drive research across the "valley of death" into commercialization.POETS uses system level analysis tools to identify barriers to increased power density. Design tools will be used to create optimal system-level and subsystem-level designs. Novel algorithm tools will address the multi-physics nature of the integrated electro-thermal problem via structural optimization. Once barriers are identified, POETS will cultivate enabling technologies to overcome them. The operation of these systems necessitates development of heterogeneous decision tools that exploit multiple time scale hierarchies and are not suitable for real-time use. Implementation of these management approaches requires new 3D power electronics architectures that surpass current 2D designs. The thermal management will be tightly coupled with new 3D electronic systems designs using topology optimization for power electronics, storage, etc. The new designs will tightly interweave elements such as solid state thermal switches and modular multi-length scale elements; i.e. spreaders, storage units, phase change and mass flow system interacting with convection units. Fundamental research advances will support development of the 3D component technologies. New materials systems will be developed by manipulating nanostructures to provide tunable directionality for in plane and out-of-plane thermal power flows. These will be coupled with micro- and nano-scale thermal routing based on new conduction/convection systems. Buffers made from phase change material will be integrated into these systems to augment classes of autonomic materials with directed power flow actuation. Novel tested systems will integrate the system knowledge enabling technologies and fundamental breakthrough into modular demonstrations.
