Operation with discontinuous input current and variable switching frequency is considered. Equations for average input current are presented, showing that quasi-sinusoidal waveforms are obtained. Also, the switching frequency equation shows an almost constant frequency operation. A design procedure is presented, where simulation and practical results show the good performance of the approach. Comparison with constant frequency operation also shows that a better harmonic distortion is obtained if the voltage in the switch (with switch off) is not far from the input voltage. Also, in this case, the high-order harmonic content is easily filtered.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126789482","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 electro-thermal simulations are performed using the Saber circuit simulator and include the control logic circuitry, the IGBT gate drivers, the physics-based IGBT electro-thermal model, and the thermal network component models for the power device silicon chips, packages, and heat sinks. It is shown that the thermal response of the silicon chip determines the IGBT temperature rise during the device switching cycle. The thermal response of the device TO247 package and silicon chip determines the device temperature rise during a single phase of the 60-Hz sinusoidal output. Also, the thermal response of the heat sink determines the device temperature rise during the system start-up and after load impedance changes. It is also shown that the full electro-thermal analysis is required to accurately describe the power losses and circuit efficiency.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"2018 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121617429","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}

Although prototype current resonant DC link topologies for AC-AC power conversion have had such problems as irregular high current peaks and uncontrollable pulse width, this new topology enables the AC-AC conversion system to have the properties wherein the current peak is limited and the pulse width is adjustable. The system begins to assume an adjustable-width flat-topped current shape, whereby the system becomes particularly suitable for high power application. With control of the pulse width a very fine load current regulation can be obtained. In this system, an open loop PWM control has been adopted and almost the same quality of output waveforms as the conventional current source inverter has been achieved.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133149974","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 power electronic system is split into a linear main circuit and nonlinear modules which are modeled by appropriate nonlinear time-varying voltage source and/or current sources. A state space model of minimum complexity is then generated using MNA, while avoiding the graph theory approach. A power electronic system can be simulated by iteratively solving the state space model thus formulated together with nonlinear modules. Moreover, the effect of switching actions on the coefficient matrix of circuit equations to be solved can be eliminated by the proposed approach. The approach is found to be compatible with the SPICE data structure. It can be used to develop powerful multilevel simulators based on SPICE or to improve SPICE capabilities for power electronic system simulation.<<ETX>>","PeriodicalId":358822,"journal":{"name":"Proceedings of IEEE Power Electronics Specialist Conference - PESC '93","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124282488","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}
