However, this leads to increased electromagnetic interference (EMI). Conventional passive filter topologies can use a considerable amount of space and contain heavy components, reducing overall power density. To minimize volume and weight of passive filters, active EMI filters can be used. In this work, a novel EMI cancellation method for pulsewidth modulation controlled three-phase motor inverters is presented in a feasibility study. This method injects a cancellation signal by applying a filter to the digital transistor control signals of the motor inverter. By slightly delaying the control signals before they reach the transistor gates, the time required to synthesize and inject the cancellation signal can be compensated. The digital filter parameters are adapted continuously based on the measured noise signal to achieve maximum filter performance. First, the new method is described in general. After that, the applicability to power electronics is discussed. For demonstration, the system is applied to a motor inverter with GaN transistors to reduce the conducted common mode EMI at the input side of the inverter. The results are shown and discussed for different operation modes.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 4","pages":"1213-1227"},"PeriodicalIF":2.5,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11089934","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is necessary to study the uncertainty of GICs affected by multidimensional input parameters to conduct a comprehensive assessment of the GICs levels in the power grid and their potential threats. The traditional polynomial chaos expansion (PCE) uncertainty analysis method incurs significantly higher computational cost in high-dimensional and high-order scenarios. Taking this into account, a PCE optimization method based on compressed sensing (CS) is proposed in this article. First, the Kriging method was employed to establish an earth conductivity model considering limited measurement data. Then, the proposed method was used to conduct the uncertainty analysis of GICs during storms in the North China UHV grid. The statistics of the maximum GICs in the North China power grid were obtained and compared with results from the Monte Carlo and PCE methods. Results indicate that the PCE method optimized by CS can efficiently analyze the uncertainty of GICs and substantially reduce the computational cost compared with the PCE method while ensuring accuracy. Finally, based on the total Sobol indices, the sensitivities of GICs to the input variables are analyzed to reasonably evaluate the threat of GICs to the power grid.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 4","pages":"1352-1359"},"PeriodicalIF":2.5,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684821","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}
