This results in attaining higher power density, smaller filter size, and lighter weight for the power converter. But the bottleneck of taking advantage of these ultra-fast devices is spurious behavior during operation due to cross talk and electromagnetic interference inheriting from higher dv/dt and di/dt. To meet the standard and to ensure robust operation, EMI filter is in place for a time being; mostly to meet conducted emission requirements. To deal with radiation, shielding is a common practice. This work aims to understand how much the EMI filter helps with radiated EMI reduction. A converter with a traditional passive EMI filter is considered to evaluate the effect of the filter on the near magnetic field adjacent to the converter. The observed phenomenon has been analyzed and explained to understand to what extent the conducted EMI filter helps with mitigating radiated emission.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131517255","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}

When the operation of high-power functions overlap and there is excess peak current consumption, a sudden voltage dip occurs from the battery to the power management unit. In this paper, we propose an active compensator method to prevent voltage dip below the under-voltage lockout (UVLO) threshold voltage in the mobile phone power distribution network. To design the active compensator circuit, a simulation model for the power delivery network is developed based on the load current profile, power delivery network PCB layout, and Lithium-Ion battery model.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123605520","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}

Those RF radiators can be modeled as a set of equivalent dipole moment(s) when they are electrically small. Then, the dipole moment based reciprocity theorem can be applied to estimate the noise coupling level. In this article, a practical methodology using the dipole moment based reciprocity is proposed to identify multiple radiation sources of a real cellphone product. Multiple equivalent dipole moments are constructed with one-to-one correspondence to the physical structures. The reciprocity calculations can eventually provide the noise contributions of each noise source.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127799000","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}

It is a public environment where people carry communication equipment and/or medical active implants. Therefore, electromagnetic interference among the devices in the hospital environment is not an unfamiliar topic. There is a misconception among engineers that if all medical devices comply with harmonized standards, then the installation of a large number of medical devices altogether would work absolutely fine. However, this is not always true, and so for complex systems, a smarter approach is necessary to assess and control the risks of electromagnetic interference. This paper emphasizes the importance of using the risk-based approach to deal with the often unpredictable factors causing electromagnetic interference in a complex hospital environment.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121205470","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}

The electric field of the standard source is regenerated with the transfer function of the log-periodic antenna. It is then compared with the original field of the standard source to validate the transfer function of the log-periodic antenna.

Automotive components are becoming more and more electronic. To ensure the reliability and safety of electronic devices with electric shock and electromagnetic compatibility, each part has protective components such as electrostatic discharge devices and fuses. In particular, as the voltage and current of high-performance vehicle engines increase, high-voltage fuses for protecting drivers and passengers from explosion are becoming more important. In addition, the development of electrical fuses is time and cost consuming due to complex multiphysics, including electric arcs and large-scale experimental environments. In this paper, we propose a model to estimate the voltage, current and internal pressure of a high voltage fuse. Using the concept of a specific action, the resistance of the fuse to induced energy is modeled. The internal pressure is modeled based on the estimated electrical power profile. The proposed model is validated with time-domain measurements and Ansys CFX simulation results. The proposed model can significantly save simulation time and it has the expandability to estimate multiple physics parameters in fuses.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"123 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127011477","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}

Only few emission standards for this frequency range are available, while the number of interference cases is growing rapidly. Most equipment will fail at a specific frequency and/or level. PLC is chosen as a victim, as the performance of the PLC is rated through well-established parameters. One of these is the Frame Error Rate (FER), which is calculated as the ratio between the erroneous frames and total received frames. The number of LED lamps has a strong correlation with the peak amplitude of the current pulses from the LED lamps and the FER of the PLC data frames.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126971769","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}
