It is based on the space vector representation of the output voltages and input currents in the complex plane. The resultant output line voltages and input phase currents do not contain low frequency harmonics. The input current displacement factor and the converter voltage gain can be freely varied, regardless of the load power factor; the only restriction being the equality of input and output active powers. The modulation technique holds for any input and output frequencies, so that it can be also applied for 3 Phi AC to DC and DC to 3 Phi AC conversion, thus making FCC a universal power conversion module.<<ETX>>","PeriodicalId":294244,"journal":{"name":"Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting","volume":"35 3-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114045788","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}

Depending on the lamp and ballast configuration the savings could be as large as 60%, and this does not include secondary savings, such as air-conditioning (higher-efficiency lamps and ballasts put less heat into the conditioned space). It is noted that most high frequency ballasts today have solved the problems of living with dirty power lines and do not inject large amounts of harmonics back on the power lines. The author discusses how this is done and at what cost. It is argued that the cost is affordable in consideration of the energy reduction capabilities, but more support is needed from the power companies to reduce the payback times for the end user.<<ETX>>","PeriodicalId":294244,"journal":{"name":"Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134175028","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}

A survey is first presented which briefly deals with the general adaptation and suitability of programmable controllers in some Swedish plants. The reasons behind the decision to use or not to use PLCs in safety systems are then investigated. The aspects of a burner control system for a certain boiler are considered. Safety and risk aspects are discussed in terms of reliability, installation, and the human element. The study shows the superiority of PLC systems over conventional relay technology, but also that PLCs are seldom used in safety connections mainly due to nontechnical factors such as human conservatism.<<ETX>>","PeriodicalId":294244,"journal":{"name":"Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134324531","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}

A noncirculating current cycloconverter drive is the most suitable for large-scale and low-speed drives, such as hot reversing mill main stands, while a circulating current cycloconverter drive is best suited for a tandem cold mill, which requires a high capability of speed control. The system can drive the mill at a quick speed response of omega /sub c/=60 rad/s in a wide speed range. This control performance increases the possibilities for improvements in the gage thickness accuracy control and in the production yield rate.<<ETX>>","PeriodicalId":294244,"journal":{"name":"Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114012790","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}

It provides self-isolation in the event of IGBT destruction, possible self-derived power supply from the IGBT power terminal voltage, and direct mounting (including electrical contacts) in the form of a PCB onto an ISOTOP package IGBT, all resulting in a reliable and modular construction, easy for maintenance.
