An induced voltage constant of the commutatorless motor is affected by the over lapping angle and the armature reaction. In the present report, we proposed that the induced voltage constant can be treated as a linear function and the vari­ous kinds of transfer functions are given with the constants. Using these transfer functions, the transient performances of the over lapping angle and the allowable commutation angle etc. and the reliable commutation limits are examined. As a result, it is cleared that the effects of the ar­mature reaction and the over lapping angle to the induced voltage constant can be treated as a increase of the equivalent armature resistance and the reliable commu­tation limit is advanced by the large leading commutation angle, the large smoothing reactor, the large damper coefficient and the small mechanical time constant.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125897387","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 results are used to gauge the performance of currently available power MOSFETs and to project the capabilities of future devices. With proper design, the channel resistance can be negligible so that the on-state resistance is that of the bulk material (~8.3xl0-9 VdsB 2.5 Ω.cm2) plus the lead resistance. A transmission line effect associated with long resistive gate electrodes could limit the speed of certain devices. Devices with the capability of switching 10 kW per cm2 of chip area and hundred kilowatt per package are theoretically possible over a very wide voltage range. A new structure is proposed that could raise the power capability by an order of magnitude in very high voltage devices.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128155005","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}
