Appropriate mathematical expressions, that enable evaluation of detuning, have become available and performance deterioration due to iron loss has been evaluated for rated speed operation in the constant flux region. The available studies are based on the measurement of iron loss with sinusoidal supply of rated frequency. This paper at first describes an experimental procedure for determination of iron loss and hence an equivalent iron loss resistance over the frequency range of interest. The procedure is based on no-load tests with PWM inverter supply and it can be executed during commissioning of the drive. The second part of the paper evaluates detuning introduced by iron loss in a rotor flux oriented induction machine, utilising the experimentally determined values of equivalent iron loss resistance. The emphasis is placed on operation in the braking region and on operation in the field weakening region. It is shown that detuning characteristics in the braking region differ from those valid in the motoring region. Detuning in the field-weakening region is found to significantly exceed the one at rated flux, rated speed operation, especially if the machine runs at high speeds with light loads. Finally, a modified rotor flux estimator, that enables compensation of the iron loss, is introduced and verified by simulation.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"9 1","pages":"1555-1561 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82512599","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}

Krishnan","doi":"10.1109/PESC.1996.548827","DOIUrl":"https://doi.org/10.1109/PESC.1996.548827","url":null,"abstract":"A new converter topology for switched reluctance motor drives is proposed in this paper. It has the advantages of minimum number of power switching devices, same voltage rating for all of them, variable DC link voltage for application to the motor windings to reduce the switching frequency of the phase switches and hence the switching and core losses but higher and fixed DC link voltage for faster commutation of phase currents. The converter provides a full four quadrant operation with the advantageous and important control features of independent energization and commutation of each phase winding. Further it requires no snubbing for its phase switches and only a minimum set of logic power supplies as all the phase switches have the same common. It has the disadvantages of requiring a chopper section with its attendant passive filter for reducing the DC link voltage for motor winding application. It is found that it is superior to many other (m+1) switch configurations, where m is the number of machine phases, due to the advantages described earlier. The principle of operation, modes of operation, design of the chopper stage, performance constraints and evaluation of the commutation time and rise in the source capacitor voltage for design of the machine side converter, merits and demerits of the proposed converter topology for the switched reluctance motor drives are systematically developed in this paper.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"8 1","pages":"1811-1816 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80860534","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}
