The quantitative characterization of the mutual interaction between two lines was evaluated by the reduction of the eye opening defining the bit error ratio (BER) of the communication link. The induced random interference signal extracted from the data transferring sequence measured by the real time digital oscilloscope qualifies the digital jitter of the communication link and was processed as a cyclostationary stochastic process. The cyclic averaging of the measured digital jitter revealed the instantaneous periodic power corresponding to the variance of the probability mass function obtained from the amplitude histograms constructed for each instant of time over the bit duration. The statistical analysis of the corrupted eye diagram was used for the evaluation of the BER for the communication link under interference crosstalk.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"61 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":"116800514","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, the fast switching of semiconductor devices may induce excessively high dv/dt and di/dt, which can cause electromagnetic interference (EMI) issues, making it difficult to satisfy electromagnetic compatibility standards. In this paper, the current conducted emission test for a three-phase motor drive system is performed based on CISPR 25 component-level testing setup for AM radio frequency band, which is from 530 kHz to 1.8 MHz. Under these conditions, common-mode (CM) noise generation mechanisms of the motor drive system are identified through measurements. It is found that the dominant mechanism is the mode conversion from differential mode (DM) switching current of the three-phase PWM inverter to CM current through the cable harness due to the imbalances in the PCB structure and EMI filter network which are at the dc input side of the three-phase inverter. Based on this finding, ground (GND) bridges are added between the digital signal and power GND nets to reduce the CM noise. The GND bridge effect on the reduction of CM noise in AM band is experimentally verified and further studied using circuit simulations.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"272 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":"125832466","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 devices are worn by the user during the measurement campaigns. The disturbance of the logged levels due to the extreme proximity with the body wearer is known as the body shadow effect (BSE). Several factors influence on the attenuation level of logged data due to the BSE. This work evaluates the influence on PEM measurements, of the wave incoming direction on the body, under dynamic conditions and at the frequency band of 2.4 GHz. By comparing experimental measurements and simulated results, the PEM wearer is modeled theoretically as a shadow angle whose value is determined in terms of maximum P-value. The shadow angle is 13° for frontal incidence, and 9°, for back incidence. The BSE corresponds to a lower loss when the waves come directly from the front of the body than when they come from the back. Therefore, the direction of the incoming waves on the human body is a dependence factor for exposure assessment.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"15 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":"127087789","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 introduction of Wide-Band-Gap (WBG) semiconductors in power electronic systems enables smaller components and higher efficiency due to higher frequencies and steeper slopes of the PWM control signals. Furthermore, the increasing energy demands lead to a raise of the voltage level up to 48 V. In contrast to high voltage automotive systems with complex shielded cables for EV (Electric Vehicles), unshielded cables are applied in 48 V cabling systems. The use of fast switching power electronic devices in combination with the increased voltage level pose a new challenge on electromagnetic compatibility in automotive environment. This paper shows investigations on the immunity of communication networks under these new conditions. Therefore, measurement and simulative analysis are presented to estimate the potential impact on the reliability of data transmission.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"298 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":"127415506","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}

Transient ground potential rise (TGPR) could couple to the cable core wire through conductive and near-field coupling ways and it will invade the secondary system eventually. Taking those two coupling ways into consideration, this paper builds a simulation model describing the technisim on how TGPR couples to the secondary cables in an UHVDC converter substation and searches for the best grounding way for suppressing disturbance voltage in secondary cables’ cores caused by TGPR. Through simulation and test, for a single cable harness with armor double-ended grounded, we propose that cable’s shielding sheath should be grounded only in protecting cabin. For a four-segment cable, we find the best grounding way is that for the harness segment between protecting cabin and terminal box, we should guarantee armor double-ended in both sides while shielding sheath be grounded only in protecting cabin, for the segment between terminal box and operating cabinet, we should guarantee armor double-ended in both ends while shielding sheath be grounded only in terminal box, what’s more, the armor and sheath among operating cabinets should be grounded only in phase B’s cabinet.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"29 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":"130520815","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}

More often, however, CAN communication errors occur, which are caused by the abnormal turn-on of the CAN transceiver. But most of these CAN communication errors are the result of the CAN transceiver detecting the ESD waveform as a normal signal, not by the snapback of the CAN transceiver. To determine the reasons why a CAN transceiver detects ESD as a normal signal, we first analyzed the bit timing logic (BTL) and the voltage waveforms on the CAN differential pair induced by ESD. Additionally, the inductance and capacitance of the test setup were analyzed to determine the contribution of these factors to CAN communication errors. Finally, based on these analysis, both software and hardware solutions to these communication errors are proposed.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"28 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":"132434512","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}
