As a relatively new power semiconductor device, little effort has been made thus far in creating an accurate model used for simulation. The only MCT model available to date is that based on the two bipolar transistor-behavioral subcircuit model. This model works well for static operation, but it has limitations in predicting the dynamic behavior of the device due to the omission of the internal device physics. The use of the lumped-charge modeling technique facilitates the inclusion of internal physical processes and the structural geometry of the device into the model. As a result, this technique provides a more realistic and accurate model than any other presently available. This model is verified through Saber(R) simulation and experimental results.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"9 1","pages":"23-28 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79910287","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 converter can be operated with PWM control because ZVS operation is achieved with an auxiliary resonant circuit that has few switching losses and handles much less power than the main power circuit as it is activated for only a small fraction of the switching cycle. Moreover, peak switch stresses are lower than those found in other proposed converters because some of the energy circulating in the auxiliary circuit is fed to the load. In the paper, the modes of converter operation are explained and analyzed, design guidelines are given, and experimental results are presented.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"104 1","pages":"76-82 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80470873","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 approach is based on the fact that the time of appearance of a voltage pulse traveling on a channel is directly proportional to the electrical length of the channel. Thus, if power pulses are fed into the inputs of a group of transmission lines sequentially, they may reach the end points simultaneously, if certain measures are taken. The first pulse should be applied to the input terminals of the longest transmission line, the second to the next, shorter transmission line and so on, the last pulse in the cycle is fed into the shortest transmission line. If the system is composed of m transmission line segments, the difference in the electrical length from line to line should be T/m, where T denotes the period of the cycle. The output peak power will be m times higher than the input peak power, due to either a rise in voltage, in current, or a combination of both. The current/voltage magnification would be defined by the choice of a suitable connection mode at the end points. The main advantages of the transmission line based topology are: (a) the switching elements the system consists of need to withstand a much lower power than the power experienced by the load, and (b) the system can operate either at extremely high frequencies or with very short rise and decay times of rectangular pulses.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"85 1","pages":"1323-1328 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80663296","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}

Since current-feedback magnetic multivibrators are highly efficient and are suitable for high-frequency operation, they are widely used as power sources for electronic equipment. Unlike voltage-feedback multivibrators, however, their circuits have no ability to protect themselves from overloading. We therefore proposed a new current-feedback multivibrator with overload protection. In this paper, the conditions for cessation of oscillation are derived by using our model of bipolar junction transistors. This model takes account of power dissipation, because the common-emitter static forward current transfer ratio depends on the collector current and the junction temperature.","PeriodicalId":19979,"journal":{"name":"PESC Record. 27th Annual IEEE Power Electronics Specialists Conference","volume":"68 1","pages":"975-980 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1996-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74491356","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}
