However, these filters often pose significant challenges, being expensive, bulky, and heavy. Such an issue is further aggravated with the latest generation of wide band gap (WBG)-based power converters. Reduction of the filter size can be achieved through conducted EMI mitigation techniques that address emissions at the source, particularly at low frequencies. Spread-spectrum modulation (SSM) has gained increasing interest to mitigate EMI, as it does not require any hardware alterations. This article investigates the effectiveness of the SSM in case of WBG traction inverters, where the switching frequency remains in the tens of kilohertz. In addition, the use of an additional switching leg to reduce the EMI was also investigated. A comparative analysis of these two techniques and their effectiveness in the common mode (CM) conducted EMI suppression is carried out. Experimental results are provided demonstrating the feasible CM conducted EMI reduction. It was found that the EMI peak at 160 kHz decreased by 2 dB in the SSM case and by 25 dB in the additional leg case.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"66 5","pages":"1412-1419"},"PeriodicalIF":2.0,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141986373","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}

Using pulsewidth modulation (PWM) for control will generate a common-mode voltage (CMV), which acts on the stray capacitance of the motor to ground and generates common-mode leakage current, increasing the conducted electromagnetic interference (EMI). In this regard, this article proposes an improved vector sequence PWM that suppresses the amplitude of the CMV while reducing the conducted EMI caused by PWM without increasing system volume and cost. The vector action sequence and PWM waveforms of the proposed strategy within each sector are presented. The high-frequency harmonics of the CMV generated by the proposed strategy and the impact of deadtime on the proposed strategy have been analyzed. The switching loss of the proposed strategy has been calculated. Compared with other modulation strategies, the proposed improved vector sequence PWM can effectively reduce the conducted EMI. The experimental results have been provided to verify the effectiveness of the proposed strategy in suppressing CMV amplitude and conducted EMI.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"66 5","pages":"1399-1411"},"PeriodicalIF":2.0,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141986374","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}

This letter focuses on the RC-based reference antenna method (RAM). Since the broadband wireless channel within the RC is frequency selective, the statistical behavior of the RAM in cases of frequency stirring (FS) is different from the other cases. However, the differences caused by the FS effects have been overlooked in the existing literatures. In this work, a statistical model of the RAM involving with FS is established and verified by measurements. It is found that the proposed model provides an accurate estimation of the statistics of the RAM regardless of the FS bandwidth, indicating that the FS effects are fully considered. The findings of this work not only provide rigorous analyses of the statistics of the RAM but also allow accurate determinations of FS parameters.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"66 5","pages":"1692-1695"},"PeriodicalIF":2.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141910246","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}

While numerous techniques exist for low-frequency applications, challenges arise at higher frequencies due to the inductive behavior inherent in grounding systems. The efficacy of low resistivity material as a solution to decrease grounding impedance at high frequencies is investigated. Through experimental studies using vertical ground electrodes with varied lengths and some backfilled with a commercial conductive aggregate compound, grounding impedance is analyzed across the frequency range between 10 Hz and 10 MHz. A considerable reduction in grounding impedance is achieved. Based on these findings and other published results, practical insights for designing effective grounding systems are derived, where alternative arrangements are proposed, exhibiting promising results for further enhancing high-frequency performance.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"66 5","pages":"1655-1664"},"PeriodicalIF":2.0,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141904313","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}

The FDTD results were first compared with the transmission line theory method results in modeling electromagnetic propagating through an infinite material sheet. Then, the proposed subcell model is used to model a metallic enclosure with a thin dielectric window. With these formulas, the proposed FDTD algorithm is applied to analyze the shielding effectiveness of some conductive enclosures with an observation window consisting of thin-weir nets in the presence of a high-power electromagnetic pulse with arbitrary polarization.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"66 5","pages":"1596-1609"},"PeriodicalIF":2.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141895583","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}
