Measurements have shown that the radiated emission from solar-panel electronics can reach considerable levels, in some cases even above CISPR 22 Class B. In this paper, the interference consequences on air traffic control communications have been investigated for different co-location distances between solar-panel systems and communication antennas. The results show that considerable interference impact, in terms of reduced communication range and increased receiver-noise level, can be caused by radiated interference from solar panels at co-location distances of 20-30 meters and below. The overall conclusion is that co-location of solar-panel systems with air traffic control communications, must be carefully analyzed not to create safety and security problems on airports.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"43 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":"129487969","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 evolutionary curve in car radios suggests that the upcoming 5G standard will also be included in future iterations. The requirements for ensuring high performance and robustness of the wireless communications systems in modern connected vehicles are significantly greater compared to systems from even a couple of years ago. The electrical and electronic devices in the vehicle emit electromagnetic interference (EMI) that disturbs the communications systems. The complexity of EMI immunity increases as multiple devices need to be integrated into the head unit. Furthermore, the wireless communications systems operate in similar frequency bands and thus the coexistence issue must also be taken into account. In this work, we propose a method to estimate the signal to interference ratio (SIR) from electromagnetic compatibility (EMC) radiated emission measurements. This approach enables estimation of the packet error rate (PER), which is used in the risk assessment process as applied to the vehicle environment scenario. Additionally, real-world measurements are also discussed to verify the accuracy of the estimations.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"1 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":"129496625","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 paper, a theory is derived which uses simple position dependent per-unit-length parameters to account to these effects. The theoretical problem of a bend on a single wire transmission line is analyzed based on the wave equations and the solution of the Green’s functions. The model is validated against a simulation model based on the method of moments. Moreover, the new model is compared to an already existing simulation model based on the BLT equations (named after Baum-Liu-Tesche) for the field-to-wire coupling of a stochastic field to transmission line networks, which does not take into account the coupling between the lines.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"7 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":"129660056","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 increased switching speed of modern semiconductor devises based on Silicon Carbide (SiC) and Gallium Nitride (GaN) further aggravates this issue. Thus, the importance of including EMC aspects in the design phase of a power electronic circuit is high and a reliable simulation model is very useful for rapid circuit testing and identification of the source of interference. However, the influence of parasitic components represents a crucial part of the coupling paths and thus has to be considered. This paper covers the development of a highly accurate simulation model including these parasitics. A major concern is the measurement of coupling capacitances which form an essential contribution to the model.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"1 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":"130629269","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 use of more power electronics results in the generation of highly distorted currents entering the distribution grid. Previous research shows that such current waveforms can cause large errors in static electricity meters. Thus, there is an imperative need to study the characteristics of these current waveforms and their impact on meter readings by performing extended measurements in households. Since it is not practical to store all the high granularity waveform data of such measurements, suitable detection methods and trigger levels need to be defined to only capture the potentially problematic current waveforms. In this paper, signal processing techniques (differentiation, Short Time Fourier Transform and Wavelet Transform) are applied to current signals in order to extract features suitable for use as a trigger. Results show that the Discrete Wavelet Transform and the filter with derivative method give the most promising results and work reliably even for very noisy signals.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"42 4 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":"132644694","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 multipath and shadowing effects the propagation of the corresponding \"signal in space\" is disturbed and deviations of the transmitted navigation content are expected. Existing analytical and numerical methods to determine the induced bearing error in space are often aimed at estimating just one value for the expected maximum error in a specified space volume or at most provide 2-dimensional observation surfaces, on which the error is represented by color mapping. However, in order to understand the propagation of bearing error in space, a 3-dimensional investigation is essential but often not realizable due to very high computational effort. In this paper a method is presented to calculate the 3-dimensional texture of the bearing error while constraining computational effort to a reasonable amount.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"14 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":"114240975","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}

One way to reduce the costs and effort for the development of a power supply system is to use a distributed system where the power supply is distributed decentral within the system. The DC-DC converters can be selected in their topology according to the circuit requirements and the advantages and disadvantages, thus making the system as a whole in EMC design simpler and inherently better, since couplings due to long supply lines, complex high-current filters and inadequately adapted circuit topologies are eliminated.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"110 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":"116189748","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 setup utilises automotive line impedance stabilisation networks, which feature a low-pass behaviour as well as a high current carrying capacity, for the decoupling between the power supply and the device under test. The performance of the proposed reference setup is assessed on the basis of measurements.
