The proposed DFC exhibits inherent semiconductor current balance, low commutation losses, unrestricted frequency output, high dynamic response and requires small AC filter compensation. Moreover, the converter offers 73% higher voltage than the traditional indirect frequency converter. Simulation based on a discrete state instantaneous transfer matrix is introduced to model the complex circuit structure. The fast processing, accuracy and generality of the model presented is used to obtain a performance comparison in a per unit basis between the proposed DFC and the widely used indirect frequency converter.<<ETX>>","PeriodicalId":432127,"journal":{"name":"Proceedings of the 1990 IEEE Colloquium in South America","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132702278","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 the various glide slope systems and the highly directional localizer antenna arrays successful ILS performance can now be achieved under the most adverse electromagnetic conditions. Several disadvantages prevent ILS from meeting the needs of aviation indefinitely. These disadvantages are discussed, and a microwave landing system is described.<<ETX>>","PeriodicalId":432127,"journal":{"name":"Proceedings of the 1990 IEEE Colloquium in South America","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123344964","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 notion of a process is crucial to its success; and in addition, a new type of engineering, based on disciplined team work, supported by systematic analysis to determine the degree and quality of the value to be added by each function or operation, forms the basis of the underlying methodology. The authors discuss the process view, process engineering, value adding analysis and lead time reduction.<<ETX>>","PeriodicalId":432127,"journal":{"name":"Proceedings of the 1990 IEEE Colloquium in South America","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125755123","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}
