In three level NPC IGCT converter, because of the complex commutation transient process, the IGCT works in different conditions such as anti-parallel diode forward recovery, reverse recovery, current commutated from anti-parallel diode to GCT and so on, the Gate-Unit must judge the conditions and do the correct responses such as status feedback, decrease the back-porch current and inner retrigger.

Due to its high power density, high reliability and easy cooling in magnets, this motor is a good candidate for electric vehicle (EV) applications. This paper proposes a new remedial control strategy for fault-tolerant operation of the R-FSPM motor drive, in which the copper loss is minimized. When the amplitudes of the remaining phases of the faulty motors are the same value, the reduced torque during fault can be remedied with minimum copper loss. The proposed remedial operation is compared with the existing one by analyzing the torque ripple and the copper loss. Finite-element analysis (FEA) is resulted, confirming that the proposed remedial operation can offer the acceptable torque performance and minimize the copper loss during the loss of one coil.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116630577","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}

Most importantly, the novel structure solves the problems of low power factor and complex process which exist in conventional transverse-flux permanent-magnet machines (TFPMs). In this paper, a staggered structure is applied for the adjacent stator teeth of a transverse-flux machine. This kind of structure has two topologies: three phases in the axial direction and three phases in the circumference direction. To minimize flux leakage, stator and permanent magnet dimensions are optimized by three-dimensional finite-element method (3-D FEM). As the key technology of TFPMLM, the method to increase power factor and force density has been investigated. And low thrust fluctuation, high power factor and force density are achieved by further optimization. The simulation results prove that the machine has both higher power factor and high efficiency.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122512745","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}
