Suitable values depend on the power system quality and system stability. Besides, the effectiveness of a low-pass filter on suppressing the electromagnetic interference (EMI) noise by Pulse width modulation (PWM) is investigated. As a well-known, total harmonic distortion of output voltage strongly relies on the filter parameters. Similarly, a transformerless topology of Photovoltaic (PV) applications with unipolar PWM has a big problem with the leakage current. Its magnitude relies on resonance condition in common-mode current loop are not clearly explained. Moreover, the common-mode (CM) and differential-mode (DM) voltages are measured by a line impedance standard network (LISN). These values need to satisfy the Electromagnetic Compatibility (EMC) limits. In some cases, an additional EMI filter is needed to restrain the high CM and DM noises under the EMC limits. The real values at the install location of the PV inverters which are measured without a LISN are totally different. So, this paper investigates the performance of the EMI filter through comprehensive simulation results for a representative PV application.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"44 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":"123917163","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 PEEC method is based on the electric field integral equation and the continuity equation. Magnetic and electric field couplings are described separately in terms of partial inductances and coefficients of potential. When the propagation delay is taken into account, they are approximated with the center-to-center assumption. Hence, the enforcement of Kirchhoff current and voltage laws results in a set of delayed differential equations. They are typically solved by using Marching On-in-Time (MOT) schemes which suffer from instabilities. In this work, the Taylor series expansion is used to manage the delays leading to an augmented PEEC time-domain solver. The derivation of the solver is detailed for conductors. Results obtained from the simulations show that the proposed method is accurate and yields good performances.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"121 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":"124175887","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}

When the performance of a common-mode filter is evaluated, it is necessary to consider not only SCC21 but also SCD21. Using these two parameters, the common-mode current flowing on the secondary side of the common-mode filter was formulated. Common-mode current is a summation of two causes: common-mode transmission and differential mode conversion from a signal source. The common-mode current depends on not only the phase relationship between SCC21 and SCD21 of the common-mode filter but also the phase relationship between the differential mode and the common mode of the signal source. Even if the same common-mode filter is used on a differential signaling system, the common-mode current increases or decreases depending on the phase of the differential mode voltage and the common-mode voltage at the signal source.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"82 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":"128487764","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}

When measuring RF impedances in common power electronic systems the result depends on the duty cycle of the device due to averaging effects as the sweep time exceeds the switching cycle duration by far. For this reason, this contribution introduces a switching cycle synchronized RF impedance analysis method. The method breaks down the slow measurement into several quick sub-measurements and allows for a characterization of RF impedances as a function of time as well as frequency. The analysis method is validated in an experimental setup on the basis of reference measurements and analytical calculations. Furthermore, first RF impedance measurement results of a simple buck converter obtained with the proposed method are discussed.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"155 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":"121086719","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}

Alongside with these fast switched voltages comes an increase of electromagnetic interference (EMI) inside the vehicle which may affect other in-vehicle systems. Especially with regard to the immunity of the latest communication and sensor systems, the in-vehicle electromagnetic compatibility (EMC) becomes a challenging aspect. This work focuses on the coupling effects between the high-voltage (HV) system and a 100Base-T1 two-wire Ethernet communication and the impact of pulse disturbances on the communications performance. Therefore, a test setup is presented which approximates the in-vehicle situation. It primarily consists of an electric vehicle traction system, which can be driven in different operating modes. An unshielded twisted pair (UTP) cable, terminated with passive load networks routed in parallel, is used to measure and analyze the coupled disturbance signal at its termination networks. Subsequently, in a second setup, immunity tests on an active communication line are performed in order to determine the impact of the coupled pulse disturbance on the performance of the communication channel.","PeriodicalId":332251,"journal":{"name":"2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"133 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":"121094725","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}
