A correct prediction of electromagnetic interference (EMI) (conducted and radiated) requires not only accurate models for the EMI sources and conduction paths, but also a combination of simulation/analysis tools. This multidomain simulation approach is comprised of circuit simulation tools, finite element analysis (FEA) tools, and computational tools for post processing data. For this information to be meaningful, a correct understanding of the EMI standards and the relationship between emissions and susceptibility is required. A full and flexible switching model is developed and implemented with a differential equation-based continuous simulation tool (simulink). Experimental results show that this model accurately predicts conducted EMI up to 300 kHz on a lower voltage/horsepower system. The model is then appropriately applied to the full multiMW drive system and multidomain modeling techniques are demonstrated. Circuit-based simulators (simpIorer/PSim) which better reflect power semiconductor impact on conducted EMI are used in cosimulation with the existing simulink model. Stator currents generated from this full multiMW drive model are fed into a FEA model which is used to predict the radiated magnetic field of a given cable grouping between the motor and drive. Matlab scripts are used to post-process data for comparison with EMI standards. The multidomain simulation approach is shown to be effective in predicting both conducted and radiated emissions, thus helping to make design decisions to ensure compatibility of the final medium voltage, multiMW drive system.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128804753","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, a kinetics model was developed to characterize the chemical reactions taking place in a nonthermal plasma denitrification processes using a Matlab programs. The typical gas composition in this model is N/sub 2//O/sub 2//H/sub 2/O/CO/sub 2/=74/5/6/15 with 500 ppm NO and 1000 ppm SO/sub 2/ at the atmospheric pressure and 300 K. The calculations indicate that nitrogen oxide is removed principally by reactions with OH radicals to produce nitric acid. The removal rate of NO increased with increasing water vapor and oxygen content in the flue gas indicates. The presence of both O/sub 2/ and H/sub 2/O in the gas mixture gives the possibility to form a more extensive and reactive set of radicals for the oxidation of NO.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129262779","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}

Major problems in large lighting systems with luminaries equipped by standard electromagnetic ballasts are inducted current oscillations. Those oscillations occur under normal operating conditions because of presence of good-quality resonant circuit formed by parasitic net inductance and compensation capacitors of luminaries. Current oscillations causes power loses and can cause malfunction of power grid. This paper contains results from the comparison of four basic layouts of large lighting systems with electromagnetic ballasts. For analysis and verification of this problem was used mathematical model of lighting system and measurements on real systems.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116256824","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}

By incorporating integration technologies into, and on, the PCB structure, improvement in power density and thermal performance of critical components are achieved without the addition of extra, expensive material.

Theory to evaluate the thermal management efficiency is applied to a case study flyback converter that has been geometrically integrated and thermally revised. The improvement of the thermal management efficiency in conjunction with a geometrical integration process forms the core of the paper, validated by experimental measurements.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116498123","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 scheme, the five-phase permanent magnet (PM) motor continues operating safely under loss of up to two phases without any additional hardware connections. This feature is very important in traction and propulsion applications where high reliability is of major importance. The five-phase PM motors with sinusoidal and quasi-rectangular back-EMFs have been considered. To obtain the new set of phase currents to be applied to the motor during fault in stator phases or inverter legs, the torque producing MMF by the stator is kept constant under healthy and faulty conditions for both cases. Simulation and experimental results are provided to verify that the five-phase motor continues operating continuously and steadily under faulty conditions.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124104757","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}
