Wide and ultrawide bandgap (WBG/UWBG) power semiconductor devices have significant benefits in a variety of applications from electric vehicles to grid-interface power electronics. However, these systems are subject to a number of challenges and bottlenecks. Notably, WBG devices typically operate at high-voltages, often in floating or isolated domains; they also require high-frequency and accurate control and, importantly, a means to power floating and isolated gate drivers. However, conventional isolated gate drivers rely on electromagnetic isolation which scales poorly to small size, is expensive, lossy, and prone to electromagnetic interference. This work will address the needs of future high-voltage (HV), harsh-environment power electronics for isolated power transfer such as can be used for WBG/UWBG gate drivers as well as associated sensors, transducers, and embedded controllers. Specifically, this project will develop platforms which use integrated/isolated optical-wireless power transfer as a means to deliver both power and data (for control, feedback, and fault detection) in future HV power electronics. Smaller, faster, optically isolated power and signal interfaces may have broader impacts in a range of modern power and energy systems from renewable energy and electrified transportation to performance computing and communications infrastructure. The project will also provide workforce development through training of graduate and undergraduate students in critical areas of need, integration of research and teaching, and connecting research to k-12 students and the general public through organized dissemination and outreach.The project will be completed by an interdisciplinary team that leverages skills in semiconductor design, optics and photonics, power electronics, and integrated circuits. The project is designed to maximize synergies and explore challenges at the boundaries of these disciplines. Specifically, in this proposal we will 1) study and optimize single- and multi-chip photovoltaic-mode optical power and signal receivers with high-efficiency monochromatic isolated power transfer; 2) develop nanophotonics and package structures that can improve photon capture via light trapping and photon recycling; 3) design a pseudo-adiabatic switched capacitor gate-driver that can increase optoelectronic system efficiency, reduce overall gate-drive power, and provide local control, diagnostics, and communication; 4) develop kV-level isolated packaging, integration, and assembly schemes that combine OPT and IC functions; 5) complete a final system demonstration of a HV hybrid switched capacitor DC-DC converter prototype. By using a system approach, we aim to show that optical power combined with specifically tailored, integrated electronics can increase efficiency, while reducing size, and enable new directions and opportunities in high-voltage and harsh-environment power and energy systems.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.

宽和超级带隙（WBG/UWBG）电源半导体设备在从电动汽车到网格接口电气电子设备的各种应用中都具有重大好处。但是，这些系统应面临许多挑战和瓶颈。值得注意的是，WBG设备通常以高压（通常是在浮动或孤立的域）运行。他们还需要高频和准确的控制，重要的是，一种手段，用于浮动和隔离的栅极驱动器。但是，常规的隔离栅极驱动器依赖于电磁隔离，该电磁隔离尺寸较小，尺寸较小，昂贵，有损失且容易受到电磁干扰。这项工作将满足未来高压（HV）的需求，用于隔离功率传输的艰难环境电力电子设备，例如可用于WBG/UWBG栅极驱动程序以及相关的传感器，传感器和嵌入式控制器。具体而言，该项目将开发平台，这些平台使用集成/隔离的无线电传输作为在未来的HV Power Electronics中同时提供功率和数据（用于控制，反馈和故障检测）的手段。较小，更快，光学隔离的功率和信号界面可能会在一系列现代动力和能源系统中产生更大的影响，从可再生能源和电气运输到性能计算和通信基础设施。该项目还将通过培训研究生和本科生在需要的关键领域，研究和教学的整合以及通过有组织的传播和宣传将研究与K-12学生和公众联系起来的培训。该项目将由一个跨学科团队，利用半导体设计，光学和光子学，电力电子和集成电路的技能。该项目旨在最大化协同作用并探索这些学科边界的挑战。具体而言，在本提案中，我们将1）研究并优化具有高效率单色隔离功率传递的单芯片和多芯片光伏模式光电功率和信号接收器； 2）开发可以通过光捕获和光子回收来改善光子捕获的纳米素体和包装结构； 3）设计一个伪绝热的开关电容器闸驱动器，可以提高光电系统效率，降低整体闸门驱动力，并提供局部控制，诊断和通信； 4）开发组合OPT和IC功能的KV级隔离包装，集成和组装方案； 5）完成HV混合动力开关电容器DC-DC转换器原型的最终系统演示。通过使用系统方法，我们的目的是表明，光电能力与特定量身定制的集成电子产品可以提高效率，同时降低尺寸，并启用高压和恶劣环境电源和能源的新方向和机遇。 NSF的法定使命，并使用基金会的知识分子优点和更广泛的影响审查标准来评估值得支持。
