Intellectual MeritThis research will explore the use of highly-integrated power electronics to improve the energy production of photovoltaic (PV) systems. We will develop a process for 3-D integration of power magnetics, power conversion circuitry, and a range of moderate to high density capacitor technologies using commercially available CMOS technologies and custom back-end processing. A second focus will be on efficient, high power-density circuit designs that can exploit the maximum capabilities of integrated passive and active devices. In particular, we will explore the use of resonant switched-capacitor (ReSC) converters, used in partial power processing architectures that can be integrated with groups of PV cells at the sub-module level to efficiently and cost effectively mitigate power that is lost due to mismatch at the cell, module, and system level. Targets include achieving effective conversion efficiencies over 99% for a range of operating scenarios, insertion loss below 0.1%, and a roadmap for cost of module-integrated electronics below 5 ¢/Wp.Broader ImpactPresently, variations among PV cells and differences in how much insolation they receive greatly limit the practical energy extraction that is possible and impose undesired constraints on the system configuration and grid interface electronics. The proposed research aims to eliminate these obstacles, resulting in PV systems of much greater robustness, flexibility and energy extraction capability, while maintaining low cost of the conversion electronics. Developing power electronics solutions and components that can be fully integrated in silicon integrated circuits (ICs) can support the path to grid-parity for PV systems, but can also impact other areas of acute need such as LED lighting, and power delivery for a range of consumer and industrial electronics.In addition, the tools and techniques developed in this project will be used extensively for teaching and dissemination of scientific knowledge to the next generation of engineers, scientists and educators. The research will augment the educational experience at Dartmouth in specific courses and the broader curriculum. The program will also be used to enhance our community outreach efforts. Dartmouth K-12 outreach, including regular classroom visits by the principal investigators and involvement in summer engineering workshops for high-school students will motivate new activities that leverage students' interest in solar energy to drive engagement with technical concepts, helping to make these concepts accessible and meaningful.

知识分子的研究将探讨使用高度集成的电力电子来改善光伏（PV）系统的能源生产。我们将使用市售的CMOS技术和自定义后端处理来开发3-D集成电源磁化，功率转换电路以及一系列中等至高密度电容器技术的过程。第二个重点将放在有效的高功率密度电路设计上，该设计可以探索集成的被动和主动设备的最大功能。特别是，我们将探索使用谐振开关电容器（RESC）转换器的使用，这些转换器用于部分电源处理体系结构，可以与子模块级别的PV组集成在一起，以有效并有效地减轻由于细胞，模块和系统级别的不匹配而丢失的功率。目标包括在一系列操作场景中实现超过99％的有效转换效率，插入损失低于0.1％以及模块集成电子设备的成本低于5¢/wp/wp.boader的影响。拟议的研究旨在消除这些障碍，从而导致PV系统具有更大的鲁棒性，灵活性和能量提取能力，同时保持了转换电子产品的低成本。开发电力电子设备解决方案和可以完全集成到硅综合电路（ICS）可以支持PV系统的电网准则的途径，但也可以影响其他急需的急需领域，例如LED照明，以及用于一系列消费者和工业电子学的电力传递。教育工作者。这项研究将在特定课程和更广泛的课程中扩大达特茅斯的教育经验。该计划还将用于增强我们的社区外展工作。达特茅斯K-12外展活动，包括主要研究人员的定期课堂访问以及针对高中生的夏季工程研讨会的参与，将激励新的活动，这些活动利用学生对太阳能的兴趣来推动与技术概念的参与，从而使这些概念变得易于访问和有意义。
