The proposed method uses a decoupling network (DN) to eliminate common-mode (CM) radiation generated from a high-speed connector to a nearby antenna. The DN comprises a six-port coupler on the connector side, a four-port coupler on the antenna side, and a phase delay line. This article presents the design concept, detailed signal flow graph analysis, and a step-by-step design procedure for implementing the DN. To demonstrate the effectiveness of the approach, a DN was designed and implemented for a universal serial bus (USB) 3.0 connector and a planar inverted-F antenna operating at 2.475 GHz. Both simulation and measurement results are presented, showing good agreement. The implemented DN achieved about 25-dB reduction in CM noise coupling at the target frequency and at least 10-dB reduction over a wide frequency range from 2.43 to 2.55 GHz. This validates the outstanding performance of the proposed method in mitigating RFI issues in compact electronic devices with high-speed interfaces. Furthermore, the proposed DN does not affect the normal operation of both the antenna and the high-speed differential signals.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 4","pages":"1129-1138"},"PeriodicalIF":2.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this progress presents new challenges in controlling electromagnetic interference (EMI). Traditional passive EMI filters (PEFs) effectively suppress EMI, but are constrained by their size and weight, limiting power density improvements in converters. To address these issues, this article introduces an innovative strategy combining chaotic pulsewidth modulation (PWM) with Gaussian waveforms to produce chaotic Gaussian PWM (CGPWM). While CGPWM demonstrates excellent performance in reducing high-frequency EMI, stringent electromagnetic compatibility standards still necessitate the use of robust passive filters. Accordingly, this article designs a PEF based on CGPWM, aimed at enhancing EMI suppression while significantly reducing the size and inductance of common-mode (CM) inductors. By examining the spectrum reduction effects of square, Gaussian, and chaotic Gaussian waveforms, an optimized PEF is developed based on CGPWM. Experimental results reveal that this integrated approach reduces CM inductor volume by over 74.28% and inductance by 60%, achieving up to 50 dB of EMI attenuation. These outcomes highlight the potential of combining CGPWM and PEF for effective EMI suppression and minimized filter size, making it a promising solution for high-density power electronics.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 4","pages":"1171-1181"},"PeriodicalIF":2.5,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, manufacturers are increasingly focused on reducing the complexity of power converters and enhancing the production and assembly process by transitioning from modular to highly integrated designs, which are high-density bidirectional converters (HDBCs). As a result, near-field (NF) coupling is becoming a concern for stable operation in HDBCs. Optimization for the power loop and gate drive (GD) can be achieved through computational electromagnetics tools and circuit simulators, allowing for a detailed visualization of NF distributions. In addition, the GD impedance can be fine-tuned by optimizing the gate-source trace layout, while near-electric field coupling must be considered when implementing a shielding layer between the GD and high <inline-formula><tex-math>$text{d}mathbf {v}/text{d}mathbf {t}$</tex-math></inline-formula> nodes.

This article leverages advanced machine learning techniques to accurately and efficiently predict the maximum 3-m radiated electric field of pinmap packages. Among the various models tested, the convolutional neural network (CNN) demonstrated the best performance. When combined with the Adam optimizer, the CNN achieved an average relative error of less than 1.5% across the 6 to 20 GHz frequency range. The trained CNN model’s prediction speed is several orders of magnitude faster than full-wave simulation methods. Furthermore, this article proposes a structural optimization method to minimize radiation in pinmap packages.
