The method utilizes a numerical optimization procedure which facilitates computer-aided design. It is found that better performance can be achieved than with a traditional two-step design process where the power stage and controller are designed sequentially. Optimization and simulation results for a buck power converter are presented to illustrate the design process and benefits.","PeriodicalId":126938,"journal":{"name":"5th IEEE Workshop on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122798853","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}

An interval mathematics (IM) approach is adopted to evaluate the interval extensions of DC conversion ratio and AC frequency response of switching converters, to be used in control systems design, accounting for the joint action of all the uncertainty sources. The analysis of a DC-DC quadratic converter is considered, with a discussion of various techniques for minimizing the IM overestimate of true sensitivity. The differences between the results obtained using both averaging-based and exact models are highlighted and the most remarkable computational aspects connected to IM-based numerical computing are emphasized.","PeriodicalId":126938,"journal":{"name":"5th IEEE Workshop on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124915650","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 general scheme for constructing small-signal difference equations used in sampled-data models is given. This scheme overcomes the limitations of current approaches used in obtaining input-to-output responses. However, in common with all other sampled-data modelling approaches, problems of accuracy and appropriate choice of formulation of difference equations still remain. Consequently, the use of sampled-data models to determine frequency response is not recommended. However, the difference equation formulation scheme developed here may be used in a small-signal describing function modelling approach which is demonstrated by the authors to be accurate, have no ambiguity of use and no frequency limitations-in contrast to sampled-data modelling.","PeriodicalId":126938,"journal":{"name":"5th IEEE Workshop on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126186627","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}

Use of /spl mu/, the structured singular value, is made which obviates the need for time intensive Monte-Carlo simulation runs and also guarantees the assessment of the worst case condition of the system. Furthermore, through the use of newly developed software routines for /spl mu/, the effect of up to a hundred uncertainties may be taken into account. The analysis procedure entails isolating component value uncertainties from the nominal system and arranging into a standard /spl Delta/-M structure. Subsequent determination of /spl mu/ for this structure along with the small-gain theorem enables a robustness assessment to be made for the system under study. Two procedures are given which enable reduction of a switching regulator system to /spl Delta/-M form. The first considers uncertainties to exist only in inductor and capacitor values. The other extends the formulation to encompass resistance uncertainties as well. An example is given of a regulator design for which an assessment is made of the allowed component tolerances which guarantees a lower limit of the phase margin.","PeriodicalId":126938,"journal":{"name":"5th IEEE Workshop on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116899134","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}
