This is the same frequency band as aircraft radio altimeters. In this paper, to investigate the coexistence conditions, the radio altimeter interference path loss (IPL) due to an assumed WAIC device is investigated. Firstly, an overview of the Beechcraft B300, a medium sized turboprop aircraft, is given. Then, the radio altimeter IPL measurement set-up is discussed. The measurement set-up and procedures are based on the RTCA DO-307A procedure. Finally, the IPL values are calculated using the measurement results. The minimum IPL value with the transmitting antenna inside of the cabin is 72.8 dB. This is not significantly small compared with that of the Airbus A321 (74.4 dB). In addition, the median IPL value with the transmitting antenna inside of the cabin is 90.9 dB.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"25 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114209015","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, different monopoles are assembled modifying the 3D printing structure when a conductive filament is employed to fabricate the radiating element. Measurements of the S11 parameter are combined with electromagnetic simulations to determine the different performances of the built antennas. The results highlight that the definition of the printing parameters has a strong influence on the conductivity of the resulting 3D printed monopoles, producing remarkable variations at the antenna performance.

Considering power electronic systems in stationary operation and with periodic control signals, the disturbances consist of stable harmonics that can be individually suppressed by destructive sine waves. These sine waves can be superposed to create a synthesized broadband cancellation signal that must be injected in synchronicity with the operation of the power electronic system. Since bothersome effects (like time constants or delay times) can be compensated by appropriate amplitudes and phases of the cancelling sine waves, the active cancellation system can achieve high EMI reductions in a wide frequency range. In this work, the method is applied to a motor inverter with a very large number of differential mode (DM) harmonics. The characteristics of the disturbances are discussed and the challenges for the active EMI cancellation system are elaborated. A suitable method for the determination and generation of the cancellation signal is introduced. This method is applied to a GaN inverter with a synchronous machine in the frequency range from 50 kHz to 30 MHz. The EMI suppression is evaluated by average and peak measurements with an EMI test receiver. The power of the generated cancellation signal is estimated.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"131 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121540356","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}

If on the one hand, the theoretical considerations available in the literature are complete and exhaustive, on the other hand, when moving to actual filter implementation, some practical considerations on the final application are mandatory. The first aspect to be carefully accounted for regards the actual source and load impedances of the system where the filter is installed. Concerning this, it will be proven that not only the impedance magnitude but also the phase plays a significant role, since disregarding it may lead to undesired oscillations, noise amplification or saturation of the electronics. Also, the non ideal behavior of the involved circuitry has to be considered when predicting the insertion loss of an active EMI filter. An enhanced circuit model of the filter is proposed and its effectiveness for the prediction of the filter insertion loss is proven by measurements on a common mode active filter in the frequency interval from 10 kHz up to 108 MHz.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"241 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113983492","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}

With the emergency of the next generation wide bandgap semiconductor device, such as silicon carbide (SiC) MOSFET, performance of the motor drive can be improved. However, the fast switching speed and serious switching ringing brought by SiC MOSFET can cause unwanted high-frequency (HF) electromagnetic interference (EMI), which may significantly reduce the reliability of the motor drive in many aspects. In order to reveal mechanism of the EMI existing in the motor drive, this paper has analyzed the influences of both HF impedance of the motor and switching characteristics of the SiC MOSFET based on relative experiment results. Influences of motor impedance on EMI have been elaborated through spectra analysis of the drain-source voltage of the SiC MOSFET, phase to ground voltage of the motor, CM voltage, phase current of the motor, and CM current. Additionally, impacts of switching performance of the SiC MOSFET on EMI are also discussed in detail. Based on the analysis above, the relationship between motor impedance, switching performance of the SiC MOSFET, and HF EMI can be figured out, which is able to provide much helpful assistance in motor drive applications.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130439908","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}
