Starting from an integral equation formulation of the field problem, we introduce a first level of compression based on the well-established Proper Orthogonal Decomposition (POD). The result is a small-scale approximation of the full-order discrete field formulation, which retains an explicit dependence on the set of free parameters defining the geometry. The evaluation of the reduced model for arbitrary parameter configurations remains very expensive, as it requires the construction of the full system equations before its projection onto a lower-dimensional space. This problem is solved by constructing a surrogate macromodel of the parameterized reduced-order system through a multivariate Fourier approximation. Numerical results applied to a moving coil over a finite ground plane show model compression above 99% while preserving accuracy on currents and fields within 1%.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"77 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131244097","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}

They may cause electromagnetic interference in vulnerable parts of the system and can even damage the motor. A time-efficient and simple method is presented based on the multiconductor transmission line (MTL) theory to predict the CM currents flowing in each path in the motor-drive system. The focus of this study is to model the motor feeding cables that form the main path of the CM current from the inverter to the motor. Two structures of motor feeding cables are considered and the results from the MTL model of each configuration are compared to its equivalent 3D full-wave simulation in CST. Also, the effect of the length of the cable on the CM current is investigated using the proposed model. The comparison between the presented model and the 3D simulation shows the validity of the model. Moreover, the presented model needs significantly less computation time in comparison with the CST model.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132532194","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 especially applies to compact high-voltage applications in electric powertrains. The phase shifted full bridge (PSFB) is commonly used as the main DC/DC converter in electric vehicles. Unfortunately, the compact size gives rise to several undesirable effects, including parasitic capacitances. These noise coupling paths enhance the propagation of electromagnetic interference (EMI), and therefore they should be minimized. To investigate how much the parasitic capacitances affect the conducted emissions, a circuit model of a 1.5kW PSFB DC/DC converter was created. With the simulation-based findings presented in this paper, developers can have a deeper understanding on the extent to which parasitic capacitances contribute to EMI in a PSFB power supply. A theoretical explanation and measurement results are provided at the end of the paper to support the conclusions of the simulation experiments.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133386442","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 accurate characterization of equipment in the extremely low-frequency domain (below several hundred kHz) should include the direct emitted electric field as well as the induced behavior of the device due to the unit-to-unit interaction. Following a detailed characterization at the unit level, the unit-to-unit interaction is attributed to the near field scattering effect, usually considering the scatterer as a small sphere. This way the induced behavior of the unit can be described by an oscillating dipole coherent to the incident field. This work highlights the importance of induced behavior of the units at the system level for accurate system predictions in the case that the scatterer can't be considered as a small sphere due to dielectric materials or complex unit geometry. The authors aim to characterize the induced behavior by solving the inverse electromagnetic scattering problem through a customized measurement procedure.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"420 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129312888","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 this work, the effects of the switching frequency of randomly modulated power converter on the G3-PLC system is investigated. To this end, a range of switching frequencies from 10 kHz-100 kHz is applied to a randomly modulated DC-DC converter and its potential effect on the G3-PLC is studied. Experimental results confirmed that switching frequencies near the bandwidth of the G3-PLC caused significant disturbance and possible coexistence issue compared to the frequencies out of this range. Moreover, there is a tradeoff between Electromagnetic Interference (EMI) reduction and coexistence issue that is Random Frequency Modulation, which is very effective for EMI reduction, is found to be very disruptive for G3-PLC, compared to alternative random modulation techniques like Random Pulse Position Modulation.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"119 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123682287","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 paper presents the equivalence between far-field and near-field coupling on an electrically short interconnected in order to derive an estimator of IC radiated susceptibility in TEM/GTEM cell from NFSI. This estimator is tested and validated on near-field scan results on a bandgap reference. Moreover, the proposed approach relies on calibrated injection probes.
