职业生涯：未来电力电子系统基于半导体的电磁干扰抑制架构电力电子转换器使用开关半导体器件实现各种形式的电能转换。高速开关操作在电力电子系统中会产生电磁噪声干扰(EMI)问题，会导致系统故障和故障。此外，除非通过标准的百代资质，否则任何产品都不能销售。电磁干扰问题被认为具有高度的复杂性和非线性，无源电磁干扰滤波器是缓解这一问题的主要解决方案。这些无源滤波器往往体积大、损耗大、成本高、对电路寄生敏感，并且需要试错。设计迭代以获得令人满意的滤波性能。此外，随着宽禁带(WBG)器件的出现，电磁干扰问题变得更加严重，因为这些新器件的di/dt和dv/dt比硅器件高得多，因此传统的无源滤波器对现代电力电子转换器的功率密度产生了不利的影响。这项拟议的项目提供了一种破坏性的基于半导体的有源滤波方法，它可以从根本上取代几十年来一直使用的无源滤波解决方案。该项目的成功不仅将显著提高未来电力电子系统的功率密度和效率，而且还将改变此类系统中EMI缓解的设计理念。拟议的项目将尖端研究与教育相结合，从而提供了一个将STEM跨学科知识与实践活动相结合的平台，重点是建立从大学预科到研究生水平的STEM学生渠道。在阿肯色大学工程学院职业意识计划(ECAP)的支持下，该项目还将培养女性和代表不足的学生参与这一STEM领域。因此，该计划将加强下一代多学科多元化STEM教育的基础设施，旨在支持电力工程劳动力的发展。针对现代WBG电子转换中的基本EMI问题，本项目的研究目标是：(1)建立一种新的基于半导体的电磁噪声抑制架构，以取代现有的无源主导滤波系统，并实现非常高的功率密度；(2)创建并展示一系列适合不同应用的基于半导体的过滤解决方案；(3)研究所谓的基于高频EMI模型的实时噪声补偿框架，作为更通用的即插即用EMI解决方案；以及(4)制定高密度EMI过滤器集成的指南。该提议的基于半导体的EMI缓解架构使用有源元件来消除？EMI实时发出噪音，因此，它可以在各种应用中自行调试。这项拟议的研究具有变革性，因为它开辟了传统研究的一个新领域。这项研究活动将不仅在现有的电力转换框架内，而且在其他电气工程子领域以及物理领域中促进对这个非线性问题的了解。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。

Title: CAREER: Semiconductor-Based Electromagnetic Interference Mitigation Architecture for Future Power Electronics SystemsPower electronic converters use switching semiconductor devices to realize various forms of electric energy conversion. High-speed switching operation generates electromagnetic noise interference (EMI) problems in power electronic systems, which can cause system failure and malfunction. Furthermore, no product can be sold unless passing standard EMI qualifications. EMI issues are considered to have high complexity and nonlinearity, with passive EMI filters being the dominating solution to mitigate this problem. These passive filters tend to be bulky, lossy, costly, sensitive to circuit parasitics, and requiring ?error-and-try? design iterations to achieve satisfactory filter performance. Moreover, EMI problem becomes even more serious with the emergence of wide bandgap (WBG) devices as these new devices have much higher di/dt and dv/dt than silicon devices, so traditional passive filters turn out to affect adversely the power density for modern power electronic converters. This proposed project provides a disruptive semiconductor-based active filtering method which could essentially replace passive filtering solutions that have been used for decades. The success of this project will not only significantly improve the power density and efficiency of future power electronic systems, but also changes the design philosophy for EMI mitigation in such systems. The proposed program integrates cutting-edge research with education, and thus, providing a platform to integrate STEM interdisciplinary knowledge together with hands-on activities with the focus on establishing a pipeline of STEM students in electrical engineering from pre-college to graduate level. With the support of the College of Engineering Career Awareness Program (ECAP) at the University of Arkansas, this project will also foster women and underrepresented students participation in this STEM field. Therefore, this program will enhance the infrastructure for next-generation multidisciplinary diversified STEM education aimed at supporting power engineering workforce development. Targeting the fundamental EMI problem in modern WBG electronics conversion, the research objectives of this project are to: (1) establish a new semiconductor-based electromagnetic noise mitigation architecture replacing existing passive-dominated filtering systems and achieving very-high power densities, (2) create and demonstrate a family of semiconductor-based filtering solutions suitable for different applications, (3) investigate the so-called high-frequency-EMI-model-based, real-time, noise compensation framework as a more general plug-&-play EMI solution, and (4) develop a guideline for high-density EMI filter integration. This proposed semiconductor-based EMI mitigation architecture uses active components to ?eliminate? EMI noises at real time, and thus, it can be self-commissioned in various applications. This proposed research is transformative in the sense that it opens a new area of traditional research. The research activity will advance the knowledge of this nonlinear problem not only in the existing power conversion framework, but also across other electrical engineering subfields as well as physics domains.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.
