The suggested method combines common-mode (CM) and differential-mode (DM) chokes within a single core structure. This approach addresses the limitations of conventional combo choke solutions, such as their inability to design CM and DM inductances independently and the complex manufacturing process. It also offers a high degree of integration and design flexibility. Compared with discrete filters, the proposed solution reduces the component size significantly while effectively balancing DM and CM filtering performance. In addition, this innovative design reduces system complexity while demonstrating excellent performance and considerable commercialization potential.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"7 3","pages":"97-103"},"PeriodicalIF":1.0,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, detecting such CMC saturation is often complex, time-consuming, and costly. This letter presents a method for detecting core saturation by introducing a high-frequency (HF) signal alongside the operational frequencies, including the fundamental switching signal and its harmonics, of a high-power system. To validate the concept, the technique is tested in a controlled environment using an HF detection signal combined with low-frequency saturating current.

Unidirectional current injection toward the DUT is necessary. An active circuit design is proposed for unidirectional current injection in high-speed simplex interfaces. The proposed method is applied to a USB3 Gen 1 interface. To verify the effectiveness of the proposed unidirectional injection structure, directionality, gain flatness, and maximum stress level are measured.

These devices can take the form of strip N-conductor structures with a various number of conducting layers, as well as cables. When designing them, during optimization, developers need to simultaneously consider several factors (e.g., the level of interference attenuation in a 50-<inline-formula> <tex-math>$Omega $ </tex-math></inline-formula> matched path with minimal mass and dimensional parameters) that the final product must satisfy. Additional complexity in the optimization of such structures is due to the variability of geometric and schematic models of them. Thus, the work details the main approaches to optimizing cable structures, including simultaneously several criteria. As global optimization algorithms, we consider a simple genetic algorithm, evolutionary strategies, and a random search method. The criteria include the amplitude criterion (minimization of the interference voltage at the structure’s output) and the matching criterion with the electrical path (minimization of reflections of useful high-frequency signals at the modal filter input). As the structures to be optimized, we take cable structures based on 3-conductor round and 2-conductor flat cables. This letter compares three algorithms, highlighting their advantages, disadvantages, peculiarities, and limitations in optimizing cable modal filters. Finally, we present practical recommendations for the use of optimization algorithms that are useful for designers of noise-suppressing cable devices.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"7 2","pages":"55-60"},"PeriodicalIF":0.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
