The method is aimed at providing a suitable data structure for time-domain simulations, supporting the automatic determination of the topology entered by SRLC nets after forced commutations of any switching device. The data structure consists in a Master-Slave Connection Matrix, defined using the compensation theorem, which permits a straight evaluation of the influence of the forced commutation of any switch upon the currents of all switching devices in the net. Problems connected to the presence of controlled sources are discussed. Some applications to the simulation of power electronic circuits are presented.","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":"127946718","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 focus is on the first-order reliability method (FORM). Two circuits are analyzed: an open-loop updown power converter; and a similar closed-loop circuit that is currently in mass production. The open-loop circuit provides an example from which rich quantitative data can be obtained for various methods. The closed-loop production design circuit provides a proof-of-concept for a FORM application on a complex design. The implementation includes parallel gradient computations across six networked workstations. The parallel environment is described in detail.","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":"128495828","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 tracking application, on the other hand, a controller works to cause an average output voltage or current to follow a desired reference waveform as a function of time or some other variable. This paper describes a large-signal linear, multirate digital controller for, among other possible applications, charging electric vehicle batteries. This controller permits the charger to track and deliver a desired current trajectory for a wide range of loads while providing a unity-power factor interface to the electric utility.","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":"128587657","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 method utilizes switching operations, which are a characteristic feature of a power electronic circuit, to express a variation of a period. There is no need to include a period T as an unknown variable. This modification eliminates two disadvantages of the conventional method; one is failure of finding solutions due to wrong initial values and the other is that an initial time does not coincide with a starting time of a circuit topological mode.","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":"131299778","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 paper presents an analysis, by the finite element method, of a magnetic device (coupled three-phase inductor) used as current injection interface in a third harmonic modulation circuit. The magnetic device is designed to block fundamental currents and to offer least resistance to third harmonic currents. In order to reduce its zero sequence inductance, which may affect the operation of the diode bridge, a conductive shield is added to cover the coupled inductor. On the other hand, the conductive shield produces excessive power losses due to high eddy currents induced by the third harmonic field. The electrothermal aspect of the coupled inductor is therefore investigated. The analysis is performed using a realistic 3D model of the magnetic device.","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":"114602108","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 general, the charging process can be divided into two periods referred to as the \"bulk\" charge and the \"trickle\" charge. Since the trickle charge is restricted to relatively low battery currents, the ability to reduce the charging time depends on delivering as much current as possible during the bulk charging period. This is especially true for those instances where the trickle charge occurs infrequently or not at all. It is expected that this will be the case where some mechanism other than a trickle charge is used to equalize the individual battery voltages. Here, the authors calculate the IGBT junction temperature of electric vehicle battery chargers in order to maximize charging current delivery.","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":"116128971","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}
