The device consists of a microcomputer, keyboard and display, and an I/O interface, of which the first two are standard, and the third dedicated for the particular plant. The nature of the structure simplifies man-machine interaction, permitting the management of plant and the displaying of measurements, apparatus status etc. on two levels: local by keyboard and display, and remote by linkage with the supervision center. The authors describe mCS, illustrating its structural and functional characteristics from both the hardware and software points of view.<<ETX>>","PeriodicalId":272740,"journal":{"name":"Conference Proceedings., Eleventh International Telecommunications Energy Conference","volume":"290 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123746046","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 variation in switching frequency required to regulate the output voltage constant is narrow, and the converter has load short-circuit capability.<<ETX>>","PeriodicalId":272740,"journal":{"name":"Conference Proceedings., Eleventh International Telecommunications Energy Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122028925","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 model relies on the widely used assumption of a variable minority carrier but, unlike other analytical models, it takes into account both the majority and the minority carriers in the whole structure. Thus, exact boundary conditions can be applied to carriers and currents at the interfaces. Photocarrier generation, too, is analytically treated as a nonhomogeneous term. In order to improve the model, the authors assume hyperbolic expression of the electric field in the intrinsic region. Self-consistent determination of the field profile is obtained, minimizing the error related to the hyperbolic approximation.<<ETX>>","PeriodicalId":272740,"journal":{"name":"Conference Proceedings., Eleventh International Telecommunications Energy Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121173527","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}
