The suitability of using a multi-phase machine is in applications such as EV, HEV, shipping industry, or electric aircraft. This is due to the better properties of multiphase machines, such as higher torques, lower phase loads, smoother torque, or better fault tolerance, which is ensured by further degrees of freedom of multiphase motors. We know that the stator windings of a five-phase induction motor can be connected in three configurations. It is a star connection, pentagon connection, and pentacle connection, while in all three cases the motor will have different properties. The basis of this article is to find out how the motor will behave in case of error conditions and what effect the different stator winding configurations will have on this. The result of the article is an evaluation in which of the connections the properties of the motor during the failure are the best. All results are compared with the state when the engine was running without failure. These facts are ascertained by simulation and subsequently verified on a real engine.","PeriodicalId":117091,"journal":{"name":"2021 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"203 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123041787","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 selection of the contribution of a negative voltage sequence to the formation of the reference current vector is possible. The current control is based on the GPCC (Generalized Predictive Current Control). The power responses to changes in power references and to grid failures are shown and discussed. The results of simulation and experimental validation are presented. The strategy is able to ensure that limit values of grid current magnitudes are not exceeded.","PeriodicalId":117091,"journal":{"name":"2021 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128481788","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}
