Measurements take place in two different measurement environments, namely in a TEM-cell and in front of an absorber-covered wall. Due to little space in partly equipped enclosures, small field probes have to be used. This paper shows measurements done with a small electro-optical E-field sensor, which is used in various configurations according to the dynamic range. The measurements are done with the enclosures fully equipped with their electronic devices. Thus, the results presented here give a good overview of most realistic, possible EMC-threats of such control-units, which can hardly be obtained from simulations. The main aim of this paper is to compare the modifications of the sensor system and the two frequency ranges. Finally it is shown, that common shielded enclosures provide sufficient shielding effectiveness in the relevant frequency ranges.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133101097","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}

These systems are a part of the modern LV and MV smart grids [1-3]. Measurements have been provided from a power system consisting in multilevel inverters and a passive compensator assuring sinusoidal output voltages and zero CM voltage [4]. The presented theoretical analyses and experimental results show that the main application problem with magnetic saturation of the CM choke becomes less important in multilevel inverters with specially selected modulation. This allows a reduction in size, weight and cost of inductive components of compensators in such applications.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133438255","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, the information leakage threat was estimated from a viewpoint of the receivable distance from the information technology equipment. The radiated electromagnetic disturbance of the information technology equipment is then based on the limits of the radiated disturbance for the information technology equipment of class B provided in CISPR 22. The estimation result reveals that the receivable distance exceeds hundreds of meters from the information technology equipment, taking account of the receivable capacity of a receiver with an antenna assumed in this paper. In addition, when the receiving frequency is higher, the receivable distance is shorter, in the defined frequency range with the constant limit value defined in CISPR 22. However, the receivable distance is stepped up at the receiving frequency of 230 [MHz], because at which the limit values of the radiated disturbance for the ITE of class B is stepped up.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122848976","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}

We give some examples of specific effects that have been documented, including increased dropped-call levels on cellular telephone systems and system-wide interference on the Global Positioning System (GPS). To assess the potential and degree of risk presented by radio outbursts from the Sun, we survey what is known about the frequency of occurrence of solar bursts as a function of frequency and time. We show that a firm assessment of risk remains unknown due to lack of complete coverage in the monitoring of solar bursts, but we present some expectations based on current knowledge. We conclude that effects on wireless systems in space are likely to occur, but can be mitigated by considering and accounting for solar burst properties.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123038213","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 order to enhance the bandwidth of the suppression stopband, the proposed EBG structure is implemented by employing multi-layer printed circuit board and multiple power/ground via pairs with narrow pitch. The design concepts for the enhancement of the lower/upper bound cutoff frequency are investigated in this paper. Test boards are fabricated and measured to validate the accuracy of the design concepts. The measured results show good consistency with simulated ones. To demonstrate the influence of the power noise on RF SiP, a simulation environment including a 60 GHz power amplifier and power distribution network on the package level is established. Besides, the proposed EBG power/ground plane is employed to suppress the power noise and intermodulation distortion of the RF output spectrum.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121138510","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}
