The CISPR 16 and ANSI C63 standards mention the different site validation techniques for the test sites from 30 MHz to 18 GHz. They are based on the Normalized Site Attenuation test from 30 MHz to 1 GHz and Site VSWR test from 1 to 18 GHz. Due to the limitations of the conventional sVSWR test mentioned in the standards, an alternate method using Time Domain gating is proposed from 1 to 18 GHz. The Time Domain sVSWR method is a more robust and statistically consistent method and equivalent to the conventional sVSWR test. Although the different site validation techniques are laid out, there are no site validation methods mentioned from 18 to 40 GHz. This paper explores the site validation from 18 to 40 GHz using the Time domain sVSWR test and summarizes the test results in a 3m EMC chamber. It analyzes the various contribution factors for the measurement uncertainty budget and recommendations to reduce the sVSWR uncertainty factor. It also investigates the effect of gap in the absorber layout to the chamber validation results and the rationale for chamber validation from 18 to 40 GHz. In addition, an improved version of the CISPR 16 sVSWR test is presented and the results are compared to the time domain sVSWR method.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"114 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120872565","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}

Similarly, a hybrid LPDA-broadband-dipole antenna does not exhibit significant asymmetry in the frequency range in which the constituent LPDA acts alone in producing radiation. Nevertheless, a slight pattern asymmetry exists in such antennas due to the unbalanced excitation of the exposed center conductor of the internal coaxial line at the feed point where is emerges from the boom. That is, this small portion of the center conductor is driven against the remainder of the LPDA. The small asymmetry can be discerned in the primary lobe of the principal plane patterns but manifests itself in a less subtle manner in the antenna symmetry tests called for in several contemporary EMC standards. Perhaps surprisingly, the effect is observable at frequencies well below those at which the active region is located near the feed point. It is worthwhile to note that this behavior can exist with no common-mode (CM) current on the feed transmission line, rather only on the LPDA booms. We examine this behavior in some detail using full-wave analysis of a typical LPDA antenna including a detailed feed model. We also provide measured data showing clearly similar behavior.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125781388","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}

Digital signals from ICs can have wide-spread frequency spectrums, and radiated signals in the radio frequency range can be picked up by other radio receivers, which causes radio-frequency interference problems. First, an equivalent radiation source for an inverter chip bonded to a PCB is reconstructed based on near-field patterns measured above the chip. The validity of the reconstructed source is proved by comparing the coupled voltage measured on a victim antenna and the voltage calculated based on the reconstructed radiation source. Then, the radiation mechanism is investigated by analyzing the equivalent radiation source as well as the signal and return current paths in full-wave simulations. Then, the critical current paths responsible for the radiation are identified. Finally, a simplified model is proposed to calculate the equivalent radiation source, with which the errors between the simplified model and full-wave simulation results were found to be within 5%.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127313122","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}

Firstly, the configuration of an electric railway traction system using power electronics in Electric Multiple Units is presented. Details are provided for the electric driving system components which can influence the harmonic distorting regime (single phase traction transformer, asynchronous traction motors, power inverters and converters, static power converters and contact line). Theoretic and practical considerations related to them are included. Dynamic effects of the voltage harmonics from the power supplying network are presented. Overvoltages caused both by the power supplying network instability and respectively by current harmonics are discussed. Experimental results concerned with the instability aspects due to electric resonance at a frequency of 800 Hz were analyzed and the condition to prevent them was deduced, along with the technical solution. Experiments made before and after the designed filter introduction proved its design and implementation correctness. Overall and per-harmonic influence of the filter was revealed.","PeriodicalId":189322,"journal":{"name":"2020 IEEE International Symposium on Electromagnetic Compatibility & Signal/Power Integrity (EMCSI)","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127436301","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}
