With a constant-frequency controller, this ringing is shown to result in a widely fluctuating small-signal loop gain for relatively small changes in operating conditions. This fluctuating loop gain, which cannot be predicted by present-day smal1-signal-modeling techniques, may result in instability if not allowed for in the design process.","PeriodicalId":164857,"journal":{"name":"1986 17th Annual IEEE Power Electronics Specialists Conference","volume":"1966 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129733580","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}

This theory, unlike other methods, can be applied to both resonant and PWM converters, and gives analytic results in closed form for ideal converters. This paper discusses the special case of ideal two-switched-network converter systems in PWM, programmed, and bang-bang operation. For the examples under study, theoretical prediction and experimental results are found to differ by at most 2dB in amplitude and 10 degrees in phase at most frequencies up to three times the switching frequency. Examples are given in this paper for which the theory gives the correct prediction, while other methods fail.","PeriodicalId":164857,"journal":{"name":"1986 17th Annual IEEE Power Electronics Specialists Conference","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122108740","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}

A piecewise linearization with respect to current is crucial for extending the Floquet theory based variable transformations to this case. However, any smooth function in rotor angle 8 can be used to approximate the flux linkage characteristics. The details of a nonlinear voltage control which produce a desired torque are given in the paper. The main result can be used as a method of generalizing the Floquet theory based variable transformations for any drive, when the saturation has to be included. In this sense, the method could be used as a rigorous method of extending the vector control techniques to the case with the saturation.","PeriodicalId":164857,"journal":{"name":"1986 17th Annual IEEE Power Electronics Specialists Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132219731","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}
