The primary inverter operates in the square-wave mode, handling most of the converted power, while its output harmonic currents are compensated by the much smaller secondary inverter. As a result, the tandem inverter, to be used for AC motor control, combines the best features of current-source and voltage-source inverters. In particular, in comparison with an equivalent voltage-source inverter, switching losses are greatly reduced, current-control dynamics are improved and EMI effects on the power system are alleviated. The operating principles of the tandem inverter are described and the results of computer simulations and experiments with a laboratory model are presented.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130483123","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 ballast is intended to supply instant-start fluorescent lamps from a DC 12 V source. The use of class E amplifiers in fluorescent lamps ballasts presents large advantages such as: high power density; simple structure (only one transistor); high efficiency; and optimum lamp driving. The class E amplifier uses a capacitive impedance inverter as the resonant tank and one diode in antiparallel with the switch; these elements allow the implementation of a dimming feature for the ballast. One of the main applications of this ballast is the supply of fluorescent lamps from solar cells. The design process has been simplified obtaining several characteristics and using mathematical programs. The designed electronic ballast drives a 21 W lamp and operates at a switching frequency of 400 kHz. Dimming is implemented using a SG3524 in a VCO fashion.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121719291","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}

This paper presents a packaging technology framework for designers to better understand, evaluate and communicate the technical needs for a 'physical circuit'. The framework goes further in proposing a systematic method to link technical power packaging issues to user requirements as the basis for developing a power electronics technology roadmap. This paper presents the framework as a three-dimensional coordinate of user requirements, levels of packaging and interfaces and pathways, cross-cut by a fourth dimension of energy forms. Examples assist the reader in understanding the framework and appreciating the potential for application of the framework in the future developments of power electronics packaging.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131999403","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}
