In this paper a method is presented to substantially expand the usable frequency range of high current rated inductors. The basic idea of the method is to control the resonant frequencies of a coil by placing a gap between groups of windings and to connect a resistor network in parallel. The concept is investigated at a planar spiral topology of a coil. An appropriate equivalent circuit is developed and calculated. Systematic investigations of the coil allow stating approximations about inductance, the parasitic capacitance and resonant frequency. The concept is finally approved by real measurements on a prototype coil. In a last step the proposed HF-Coil is assembled to a prototype filter.","PeriodicalId":268582,"journal":{"name":"2009 IEEE International Symposium on Electromagnetic Compatibility","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123745315","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}

At close ranges, the fields from a Part 15.247 compliant emitter may exceed minimum standard immunity testing levels. This does not imply interference will occur, only that the device may not be qualified to operate in the EM environment near the emitter. Some recent studies have shown minimal interference between Section 15.247 equipment and commercial devices [3, 4]. Other studies have indicated that (EU) UHF interference potential can exist [5, 6]. The range at which Part 15 devices may pose a risk to electronic devices compliant with standard immunity regulations is estimated and compared to these studies. Because Radio Frequency Identification (RFID), especially passive UHF RFID, emitters may be deployed in numerous locations and in close proximity to many devices, it has been the focus of many of the studies of interference potential. RFID emitters may be one of the largest populations of the Part 15 devices, but the EMI potential of general Section 15.247 emitters is addressed.","PeriodicalId":268582,"journal":{"name":"2009 IEEE International Symposium on Electromagnetic Compatibility","volume":"30 23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133949498","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 regard to the measurement of electric field strength the test set up consist of a table with metallic surface, on which the EUT and a specified length of cable harness is to be located. This set-up is placed in an absorber lined shielded enclosure (ALSE). The question of suitability of a certain ALSE for this measurement is not yet solved. A joint task force (JTF, between CISPR/D and CISPR/A) has been established to develop an appropriate validation method. In preparation of the international work in the JTF the authors of this paper propose a validation method, which is based on an arrangement similar to the test set-up. In contrast of a real cable harness the proposed radiator is well defined, which allows using results from numerical field computations as reference values. An ALSE including table and test set-up is suitable for measurements according CISPR 25, if the deviations between measurement results and theoretical results are within certain limits. In the paper the results of the field computations and measurement results obtained in different ALSEs are shown and evaluated.","PeriodicalId":268582,"journal":{"name":"2009 IEEE International Symposium on Electromagnetic Compatibility","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123107777","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}

Solutions to resolve these problems are often not straightforward and involve the correction application of filtering and shielding devices. The process of identifying effective solutions is also not straightforward. This paper describes a real-world case study where the use of several high horsepower ASDs caused EMI problems with a cable tester in an industrial plant. Included are the approaches for investigating the problem and mitigating the problem. It is shown that the correction application of an isolation transformer combined with the application of a custom power-line filter designed for mitigation of ASD-related conducted emissions resolved the problem. Modeling is also used to show the effects of adding a shield and a filter on the motor drive cables, and then a ground noise filter between the ASD system ground and the chassis ground.","PeriodicalId":268582,"journal":{"name":"2009 IEEE International Symposium on Electromagnetic Compatibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124350017","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}

Intermodulation distortion, responsible for spectral spreading, is affected by slow memory effects. Pulsed IV measurements are used to obtain model current equations that have appropriate steady-state quiescent bias dependences related to channel temperature and trap occupancy. Thermal resistance can be measured in silicon devices by using ambient temperature adjustments to measure channel temperature changes due to quiescent self-heating. The presence of trap states in GaN HEMTs makes the assessment of thermal resistance much more difficult; however, the presence of these effects can be determined by comparing two sets of IV curves taken from quiescent bias points of equal power dissipation. Results are presented showing accurate prediction of third-, fifth-, and seventh-order intermodulation projects using an electrothermal model for a power Si MOSFET.","PeriodicalId":268582,"journal":{"name":"2009 IEEE International Symposium on Electromagnetic Compatibility","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132572523","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}
