It is recommended that AD8221 be used in common mode RF noise injection environment, and AD8220 and AD8429 be used in single-ended RF noise injection environment. The mechanism of RF noise rectification inside in-amps is also discussed. It is verified that rectification mainly happens at the non-inverting input of two op-amps in the first stage of an in-amp. The DC voltage difference between inverting input and non-inverting input of the in-amp is further amplified, which will cause a large DC offset at the output. It is shown that symmetry of the first stage in an instrumentation amplifier is very important. The asymmetry of the first stage will increase the DC offset at the output dramatically.","PeriodicalId":120342,"journal":{"name":"2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122664425","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}

Such applications can utilize sputtered shielding structures to solve electromagnetic interference (EMI) issues. To reduce the EMI issues, copper and nickel are commonly used as sputtered shielding materials. To analyze the shielding effectiveness, we applied the Schelkunoff's theory. For the verification of the Schelkunoff's theory, we simulated and measured the shielding effectiveness of copper and nickel at the frequency range between 100 kHz and 10 MHz using two identical coils.","PeriodicalId":120342,"journal":{"name":"2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124438601","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}

In order to model the distribution of the electromagnetic field inside the anechoic chamber, the CST Studio Suite simulation software was used. The modeling was performed for two types of absorbers: 3650-40- ML and 3650-50-CF. After analyzing the results obtained from the simulation of the electromagnetic field distribution, it was observed that for the frequency range 1 GHz -:- 4 GHz the performance of the 3650-40-ML material is better than that of the 3650-50-CF material. Above the frequency of 2 GHz, the performance of the two materials was similar.","PeriodicalId":120342,"journal":{"name":"2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125228607","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 major challenge is the necessity for the measurement of injected CS101 ripples under the power frequency of the EUT. The measurement of CS101 ripples on the power frequency is almost impossible without taking some extra precautions. In addition to the hard necessity of measuring the CS101 ripple voltage induced across the EUT power input, the other challenge of measuring the ripple voltage that drops across the 10 μF test capacitor under the AC power frequency of the EUT is now required by MIL-STD-461G, which aggravates the severe CS101 test conditions of AC devices. In this paper, we propose a FFT -based time domain solution and a method to instantly check the ripple voltage that drops across the power source side, in other words across the 10 μF test capacitor, during the test under the AC EUT power frequency and to verify that it is low enough and not affecting the reliability of the test. The method proposed in this paper significantly overcomes the CS101 test challenges and makes CS101 test results more accurate.","PeriodicalId":120342,"journal":{"name":"2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116909383","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., wireless charging portable devices radiate the magnetic field which has high chance to cause the malfunction of electric devices. Therefore, the interest and demand of research about suppression of radiated EMI are increased. The planar resonant reactive shield employs coil for power transfer, and closed loop and capacitor to reduce the EMI. The planar resonant reactive shield dramatically reduces the radiated magnetic field from WPT system. The shielding performance is compared using analytical method and measurement. The analytical solution and measurement show good agreement.","PeriodicalId":120342,"journal":{"name":"2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117066190","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}

Due to the enormous metrological effort as well as the dependence on weather conditions, which influences the power level of WECS, the idea of measuring the common-mode current Icm on the power line of WECS and estimating the magnetic field based on this quantity arises. Therefore, the attenuation properties of the most common tower types of WECS are examined in this work. Using the Icm and the attenuation values, a simplified procedure for the prediction of the magnetic field of WECS is presented. The achieved results allow a quick and simplified assessment of the emitted magnetic field of WECS.","PeriodicalId":120342,"journal":{"name":"2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121141300","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}
