These initial LEDs and posterior developments are widely used in very-low lighting level applications. Ternary and quaternary alloys are the bases of the present high-brightness LED's. Currently power LEDs are used in low-medium lighting applications: for instance, permanent emergency lighting systems (PELS), traffic lights, emergency exit indications, lighting in critical or strategic points, i.e. the limited lamp life in classical lamps 10.000-20.000 hours for fluorescent lamps implies short lamp-replacement times and, therefore, high maintenance costs. To overcome this situation a boost converter to supply a PELS system based in LED was developed. The topology and proposed control assure a constant current through LEDs for all the battery conditions. The long operation life (above 100.000 hours) of high efficiency LED's and a very simple electronics circuitry implies an interesting solution for this type of applications. Finally, a 30 lumens and 1 hour PELS has been built and tested.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123021849","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 integrated chips technology features structure compactness and process integrity, compared to other multilevel packaging methods. Thus, power switching module, including controller and driver, sensor and filter, and power switches can be manufactured with a planar integration technology and packaged in 3-D form. An example IPEM, incorporating power factor correction (PFC) and DC/DC switching stages for a distributed power system (DPS) front-end converter application, has been fabricated and characterized. The electrical performance improvement, which includes reduction in parasitics and increase in efficiency, has been demonstrated. Furthermore, a highly functional integrated PFC switching module with embedded capacitor, current sensor and doubled side cooling has been fabricated in an integrated planar process scheme. The obtained experimental results are presented with prototypes.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115920921","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}
