The considered WPT charging system operates at the frequency of 85 kHz with a power of 7.7 kW. The WPT system creates a very strong magnetic field that can be critical for human exposure to electromagnetic fields (EMF) and for immunity of implanted medical devices. The presence of the conductive body-frame of the vehicle permits to shield the magnetic field inside the cabin, but beside the vehicle the field level is significant. Several factors (installation position of the secondary coil; coil alignment; vehicle shape and dimensions; ground clearance; body material; etc.) that influence the magnetic field behavior are considered. Different EV-WPT coil configurations are examined and the magnetic field levels are predicted by numerical simulations. From the obtained results general guidelines for the optimal position of the WPT system are provided.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"283 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133652000","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}

This work examines the profiles of RF-EMF exposure while using portable computers inside fast train cars without internal WiFi services, based on the frequency-selective RF-EMF measurements by portable, autonomous, radiofrequency exposure monitors (REM), EME SPY 121 type, performed during journeys over the northern part of Poland (mostly across rural areas). The profiles to RF-EMF in trains were compared with exposure in laboratory conditions where internal WiFi services are available. Our study experimentally confirmed that multi-path propagation of EMF signals used by wireless links of external wireless modems of many portable computers (usually at GSM or LTE uplink frequency bands used by public mobile phone networks operated with SIM card access) may produce significantly stronger RF-EMF exposure inside train cars without internal WiFi facilities than exposure from integrated WiFi computer modems and indoor WiFi facilities usually used by portable computers inside buildings. The results obtained suggest that the use of portable computers with external modems operating with public mobile phone networks inside train cars needs to be considered as a potential scenario for the worst case of RF-EMF exposure in safety evaluation required by European Directive 2014/53/EU (radio equipment directive - RED).","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115672296","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}

These technical challenges require a wide band communication, which leads to the necessity of the development of new in-car- communication-systems (e.g. Automotive Ethernet: 100BASE-T1, 1000BASE-T1, etc.). In order to add new functions to the car there is an increasing number of new communication systems, which need to be packed more densely inside the vehicle. Nevertheless, the short distance in addition with higher data rates lead to a more likely electromagnetic coupling between the electrical devices and systems. In order to safeguard such new technologies in terms of electromagnetic compatibility (EMC), the car manufacturers usually perform component level tests before testing the integrated system in the real vehicle. New component level test setups need to be specified, which represent the coupling mechanism in the car by means of the component level test. This publication introduces a near field antenna (NFA) emission test, which is characterized via a vector network analyzer (VNA) and applied to a real communication system (Automotive Ethernet 100BASE-T1).","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115895411","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}

Because of the different result of tests, many vehicle and component makers should spend more time for the later works, and consequently cost of the product and the vehicle development increase. There are several types of difference between component EMI and vehicle RFI. First is the difference of level between them. Second is the difference of resonance frequency. Third is the difference of the specification. The last is no types of component EMI tests matches to the vehicle RFI test result. In this paper, we introduced Radiated Immunity (RI) and Bulk Current Injection (BCI) methods to analyze the difference between component EMI test and vehicle RFI test. Using these methods, we could have analyzed the difference between each component EMI level and the vehicle RFI level, and we expect that vehicle and product makers can reduce the development schedule and cost at the same time by introducing the proper component EMI specification.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115092845","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}
