Two active switches and two power diodes are used in each converter leg which is different from conventional AC/DC and three level converters. The scheme is adopted with simple commutation procedure to reduce the complexity of control to ensure effective power transformation. Conventional AC/DC converter and three level converters usually have large value of capacitor at the DC side with neutral balancing which will increase the structural complexity. This paper encloses a converter topology with simple commutation procedure to have good voltage transfer ratio capacity, leading power factor and pure sine wave with only higher order harmonics in the line side. By providing small LC filter on the line side even this harmonics can be eliminated. Switches in each leg of same phase will turn on and turn off at zero current. Theoretical analyses and simulation results are provided to verify its performance.","PeriodicalId":262597,"journal":{"name":"2006 International Conference on Power Electronic, Drives and Energy Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130583163","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}

In a switched reluctance motor (SRM), the non-sinusoidal flux waveform with different frequencies of flux reversals in various parts of the motor makes the core loss calculation difficult. The conventional method for calculation of the core loss is based on the stator pole flux density variation in the triangular fashion with the peak flux density at the rotor position corresponding to the conduction angle from the unaligned position, which will not give accurate results. In this paper, an accurate method for the calculation of the core loss based on actual flux waveforms in various parts of the SRM is presented. The proposed method is validated using the FE analysis. The difference in the core loss estimated using the proposed and the conventional methods with the one obtained using the FE analysis is 4.89% and 17.23% respectively.","PeriodicalId":262597,"journal":{"name":"2006 International Conference on Power Electronic, Drives and Energy Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130151884","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}

Design of a direct drive, Brush less DC motor is presented. Many constraints have been considered, such as the size of the motor, maximum driving current and maximum output power. The diameter and the stack length are limited by using modern analytical tools of the prototype vehicle. Nobel analytical tools are used to obtain static and dynamic characteristics of the motor and geometrical verifications for low cost efficient design.

If there is no saturation in the ferrous portion of the mutual-flux path, the flux wave in the motor approaches a sine-wave shape, but some amount of saturation always exists in a typical three phase induction motor that has the effect of reducing the peak value of the flux wave. To study this phenomena, initially, 60 Hz saturation curves were used for the teeth as well as core yoke and performance analyses of the 2 motors (5 hp 4 P, and 15 hp 4 P) were done by FEM and then in turn, separate AC saturation curves for the teeth and the core yoke derived from the normal DC saturation curve were used, and FEM analyses were done to calculate all the electrical parameters of the motors. In both the cases, computational results are compared with the tested results, and it has been found that the percentage error between computational and tested results is less in case of separate saturation curves for teeth and core yoke compared to the other case.","PeriodicalId":262597,"journal":{"name":"2006 International Conference on Power Electronic, Drives and Energy Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130815580","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}
