For an efficient machine operation, a proper control strategy has to be implemented. Because of the inherent non-linearities, the control is often based on lookup tables covering the entire operating area. The proposed control strategy relies on lookup tables only containing points on the edges of the operating area. This minimizes storage requirements and determination effort, while maintaining a sufficient level of accuracy.","PeriodicalId":122797,"journal":{"name":"2010 Emobility - Electrical Power Train","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114284780","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}

Providing easy and appropriate interfaces all special issues can be solved efficient on system level. Such a module can be mass produced even in a time where a high diversification in systems can be seen in the test fleets and prototypes. The selected cell is a basis on which a battery system is built. In the case of electric vehicles specific energy is still a very important issue. So is the thermal management as temperature influences performance and life time. In the design process of Akasol an effective thermal management with a temperature imbalance of less than 1°C within a module in a standard cycle was achieved.

DC traction motors are normally designed for medium voltage and high current (1.2kV–1.5kV and 1200–1500A). Front-End Buck-Rectifiers are a viable solution for direct conversion of high ac voltage to low dc output voltage. However several buck-rectifier modules need to be connected in input-series output-parallel (ISOP) configuration, in order to achieve the input voltage and output current sharing. In the paper, stability of the input-series-output-parallel configuration for buck rectifier is analysed through small signal model. Common duty ratio scheme is implemented. The proposed scheme is capable of equal voltage sharing, irrespective of large variation in design parameters and retains stability for perturbations in load. The configuration is extremely simple for hardware implementation, as no extra controllers are required. The performance of the circuit is verified through simulation results.","PeriodicalId":122797,"journal":{"name":"2010 Emobility - Electrical Power Train","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125460590","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}
