The conditions take fully into account the interaction of the current and voltage feedback loops, and give explicit limits for the loop gains as a function of the duty ratio and the slope of the compensation ramp. The conditions are confirmed by experiment, and it is shown that they provide more stringent limits than the conventional stability analysis. The authors also introduce the concept of subharmonic susceptibility, which is closely related to the stability conditions. This is a useful design parameter which provides a measure of the degree of stability.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129002338","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 goal is to minimize weight and cost for known thermal conditions. Alternatively, the incremental weight loss characteristics generated provide additional design information for space use when total system weight is critical. The calculated figures of 60 g of additional inductor weight per watt of loss saved can be used as part of an overall system optimization procedure.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131559822","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}

Both vehicles are equipped with modern AC traction technology and digital control systems. The author describes the design of the vehicles, the power circuits of both converter systems, the induction traction motors, and the microcomputer-based control. Both projects clearly show that AC drive systems using induction motors and GTO (gate turn-off thyristor) PWM (pulse width modulation) inverters can be successfully used in modern rail vehicles. Multisystem circuits can be implemented without excessive additional cost. Individual axle control is now state of the art for high-performance vehicles. Microcomputer controls for traction and central functions have made it possible to provide future-proof concepts.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132087607","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}
