This paper describes the design trade-offs made in selecting the PWM approach for this relatively high frequency application, and provides an overview of the performance characteristics of the circuit and key critical components. This is an off-line power supply which must operate over a wide range of MIL-STD-704 aircraft prime power interface conditions. This power supply delivers three output voltages, each f u l l y regulated, at up to 50 watts total delivered power. The design will be implemented in a high density, hybrid configuration of approximately 10 watts per cubic inch, and will include the power processor and all filtering and bypass functions, except for rectification of the AC input lines, which is done external to the module. The circuits and components used to implement the power processing stage, the feedback control and stabilization network, and the overall supervisory circuit are discussed. Performance under high frequency load conditions is covered, as well as general regulator performance. A brief comparison of operating characteristics and complexity between this topology and an equivalent series resonant circuit is also given. This paper concludes with highlights of advanced packaging techniques similar to those to be used to implement this circuit in the high density configuration.","PeriodicalId":302790,"journal":{"name":"1986 IEEE Applied Power Electronics Conference and Exposition","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131782724","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 Type I scheme [2,4], the hf inverter is switched off well in advance of the zero crossings of line voltage, allowing the line current to go to zero and enabling the LCI to turn off. A simple lossless forced commutation circuit is used in Type II [2] scheme. The effects of these schemes on line side and input dc side current harmonics are studied in the case of l-ϕ systems, neglecting the effect of controller action. The performance indices are evaluated. The results obtained from prototype experimental systems are used to verify the theory presented. The analysis presented for 1-0 systems is extended to 3-0 systems.","PeriodicalId":302790,"journal":{"name":"1986 IEEE Applied Power Electronics Conference and Exposition","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114737787","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}

Models are presented that were designed to aid the user in making financially responsible decisions concerning investment in infancy removal. A key assumption of this paper is that component infancy is the single most important factor needing attention in steady state products which have employed reasonably sound design and manufacturing practices. The value of the model is in its architecture; specific results from the application of the model will vary from business to business. The objective of this paper is to provide the Technical, Business and Financial communities the ability to communicate on such a diverse subject with a common language, toward a common goal.","PeriodicalId":302790,"journal":{"name":"1986 IEEE Applied Power Electronics Conference and Exposition","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124378061","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}
