This precision regulated charging system is used in the transmitter to charge the PFN in a 14- megawatt peak power modulator to over 3,000 volts. The technique used completely eliminates the need for the con­ ventional regulated, high voltage power supply and the dissipative tube-type shunt regulator used in older line type modulators. The circuit stores a measured amount of energy in a transformer in proportion to transformer in­ ductance and current flow (E = 1/2LI2), and then transfers this energy to the PFN with the resulting voltage being pro­ portional to PFN capacitance (E = 1/2CV2). This is ac­ complished by utilizing two banks of 36 parallel connected transistors, in conventional T0-3 packages, to switch cur­ rents in excess of 500 amps.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130411225","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 first is that a ramp function, used to eliminate a potential instability, can be chosen uniquely to assure both stability and the fastest possible transient response of the programmed current. The second is the development of an extension of the state-space averaging technique by means of which both the input and output small-signal properties of any such converter may be accurately represented by a linear small-signal equivalent-circuit model. The model is presented and experimentally verified for the cuk converter and for the conventional buck, boost, and buck-boost converters.

The tableau approach, whose principle of analysis is mathematically equivalent to the state-space approach, is nontrivially modified for thyristor circuits and its numerical performance is shown to be distinct from that based on the statespace approach. It should be stressed that the initial-value computation after switching actions and the detection of network disconnection due to ideal switching actions are automatically handled without any recourse to the network graph of the given thyristor circuit. Another feature is that any program thus implemented can be extended for more complex thyristor circuits, say from static to kinestatic energy conversion systems. An extension to an induction-motor load will be presented.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122111071","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}

It differs from prior approaches in that it addresses converters according to func­ tion rather than topology, and in the way conver­ ter analyses are approached. Relationships be­ tween converters are clarified, the inherent un­ desirable aspects of switching converters are seg­ regated from those specific to particular cases and the act of commutation is shown to be an in­ dependent function of internal converter operation with little influence on external terminal per­ formance. The theory has been well tested in the classroom and used to provide the basis for analy­ ses in a practical working development laboratory. It has withstood both tests; students grasp it readily and from it develop a good understanding of Power Electronics, while in the working environ­ ment it has proved beneficial in facilitating studies and comparisons of converters for many applications, and in aiding design efforts.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132864199","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}

Power transistors are switched by PWM voltage made of the core unit mentioned above. This switching action eliminates the harmonics lower than n-th from supplied squarewave source. This output is followed by a simple lowpass filter and becomes sinusoidal wave. In temperature stability, reliability and power consumption, this method is superior to the conventional PWM method by comparing sinusoidal wave to triangular wave or using a digital circuit, because the number of constructing elements is less than that in conventional method.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114401328","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}
