Experimental results demonstrate that strong eccentricity levels are easily predicted for different load values, either with a delta or a wye connection of machine stator windings.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"15 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120905382","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}

A shunt APLC and/or shunt passive power filters (PPFs) are used to reduce harmonic distortion. Special attention is given to the shunt APLC rating when it is used with shunt PPFs for harmonic distortion reduction.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124972003","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}

Both converters use capacitive output filters, solving the problem of high reverse recovery losses associated with hard turn-off transients of the rectifier diodes. The comparison is based on a state space analysis of the converters. The effects of the parasitic switch capacitances are considered. Optimum design criteria for minimum component stress of both converters are derived. Thus, the ratings of all components are minimized and the efficiency of the converters is enhanced considerable. The advantages of the converters are compared using voltage gain characteristics and stress characteristics. Practical applications of both converters are presented and verified in experimental prototypes.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125543492","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}

A charge coupled device (CCD) line sensor was used to detect the object pattern, and a DSP (TMS32025) performed the spatial filtering calculations. Because the selectivity of the spatial filter was fixed, the measurement accuracy of this approach is generally influenced by the condition of the object pattern. A method that improves the accuracy of the velocity measurement by using two pairs of spatial filters with phases orthogonal spatial weighing functions was developed. The new method of velocity measurement is described with some experimental results.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128359156","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 new control philosophy is dedicated to the reduction of the harmonic voltage distortion caused by many distributed harmonic generating loads. Harmonic disturbance problems, the neural network control algorithm of the active filter, and test results on a small-scale power system simulator are presented. The voltage distortion becomes lower than 1% because of the active filter operation, even under the condition that maximum voltage distortion exceed 7% without the active filter.
