The subject of the workshop was \"Power Conversion Technology in the Year 2000\". The object of the workshop was for a group of knowledgeable individuals to project trends and needs for commercial power products (computing, communications, and general electronics). The areas of power that were discussed fell into three categories: AC-DC converters up to 500 watts; DC-DC converters 50 to 300 watts; and portable DC-DC converters 10 to 25 watts. These categories were chosen because they are expected to be high volume power systems, and the areas that are projected to grow significantly in the years upto 2000.<<ETX>>","PeriodicalId":335367,"journal":{"name":"Proceedings of 1995 IEEE Applied Power Electronics Conference and Exposition - APEC'95","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117112423","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}

Design for end-of-life is the consideration during the design process for the cost effective disposition of a product when it is no longer needed or wanted. We are familiar with DFM (design for manufacturing) and DFA (design for assembly), but these activities, if not done properly, can be in conflict with design for end-of-life. The author briefly discusses the incentive for recycling of materials, and then briefly discusses ways to minimise end-of-life costs including: design for disassembly, material selection, and material identification.<<ETX>>","PeriodicalId":335367,"journal":{"name":"Proceedings of 1995 IEEE Applied Power Electronics Conference and Exposition - APEC'95","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124834520","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 proposed topology combines both passive and active filters to obtain the lowest power converter VA rating as compared to the power converter rating in the active filter and the series-active hybrid filter configurations. This is demonstrated with experimental results from a laboratory model. Transient and steady state operation of the hybrid-active filter is also presented. The control of the proposed filter is extended to provide damping of resonances due to neighboring loads. Simulation results showing the effect of active damping are presented.<<ETX>>","PeriodicalId":335367,"journal":{"name":"Proceedings of 1995 IEEE Applied Power Electronics Conference and Exposition - APEC'95","volume":"334 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123775060","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}

Its basic structure is that of a quasi-resonant power converter, with an additional two active switches and four diodes. The resonant capacitors are not discrete elements, the parasitic capacitances of the MOSFETs play the role of resonant capacitors. All switches are subjected to voltage and current stresses at the same level as those in their PWM hard-switching counterparts. The power converter exhibits high efficiency and large regulation capability, based on a duty-cycle control. The soft-switching condition is maintained for a wide line range and load range.<<ETX>>","PeriodicalId":335367,"journal":{"name":"Proceedings of 1995 IEEE Applied Power Electronics Conference and Exposition - APEC'95","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129435416","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}
