It uses a linearized switch characteristic and a nonideal equivalent circuit model for each semiconductor device to avoid the drawbacks of the ideal switch concept. To obtain a more accurate switch model for simulation, we use not only the linearization of characteristic of switching devices, but also we take into account their dynamic properties. The switch model consists of a current source in parallel with a resistor-inductor-voltage source series network. Since the modelling resistance and inductance in the equivalent circuit are constant, the system matrix is constant, regardless of the state of the switch. The linearized switch characteristic is obtained by arranging the value of current source in the model, during the simulation. No switching relationship between the externally and internally controlled switches is assumed. No prior knowledge of circuit operating is necessary in order to conduct the simulation. The network equations are generated by using modified nodal formulation, and thus, a reduction of circuit formulation and computing time is obtained. An example is included. The results confirmed the accuracy and generality of the method.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124183911","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}

With the 75-300 MHz and faster clock rates of today, computer manufactures are faced with problems never seen before. It is no longer possible to ignore the inductance and resistance of device pins and power planes or the 0.5 V ring that occurs after a TTL (transistor-transistor logic), clock or signal edge. Power supplies can no longer be connected to systems with 6 ft power cables, at least not without adding large amounts of bulk decoupling capacitors. With today's newer ECL (emitter coupled logic), NTL (NMOS transistor logic) or GTL (gunning transistor logic) that only have a 0.8 to 1 V logic swings, a 0.5 V ring is going to cause definite problems in the signals. Powering today's processors and associated high speed data buses has brought a new world of challenges from a power supply stand point. Within some areas in a system, \"distributed power\" is the only practical solution. Bus terminators are one of these areas. Though, at a circuit card level, distributed power is not new, having to mount the power supply in very close proximity to the circuits that are being powered is fairly new to many. This article aims to help understand the problems involved and to point toward possible solutions.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117024241","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 system has continuous sinusoidal time behavior of the input currents and high-frequency isolation of the output voltage which is controlled in a highly dynamic manner. As compared to a conventional two-stage realization, this system has substantially lower complexity and allows to realize several isolated output circuits with minimum effort. The basic function of the new PWM rectifier system is described based on the conducting states occurring within a pulse period. Furthermore, a straightforward space vector oriented method for the system control is proposed which guarantees a symmetric magnetization of the transformer. Also, it makes possible a sinusoidal control of the mains phase currents in phase with the associated phase voltages. By digital simulation the theoretical considerations, the stresses on the power semiconductors of the new converter system are determined. Finally, problems of a practical realization of the system are discussed, as well as the direct start-up and the short circuit protection of the converter. Also, the advantages and disadvantages of the new converter system are compiled in the form of an overview.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121969509","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}
