The first paper by Katta of the Teito Rapid Transit Authority and eight colleagues from Hitachi present the details of a control strategy for a 1,500 V, 1,000 KVA PWM inverter drive for a transit car. At low speeds the torque is adjusted by increasing the inverter current amplitude and frequency proportional to a torque demand. Upon reaching a predetermined inverter output voltage at high speed a control automatically switches over to a voltage regulated system. The system is operational on a standard TRTA transit car and measured results of various tests are given in the paper.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"59 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120848295","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 non-dissipatively controlled, nonlinear resonant oscillator is used to extract electric energy directly from the phase pairs of the polyphase supply line and to generate a mixed amplitude and frequency modulated carrier. The demodulated carrier and the therefrom resulting 20 kHz pulse train produces, after being pro­cessed by a high frequency filter, an active, low frequency filtering effect for attenuation of the 360 Hz ripple of the apparently \"rectified\" three phase supply line.The system is governed by means of a pulse area control mechanism with a verified response time of one 10 kHz cycle, or 100 micro­-seconds. The customary dc link between the three phase line and the converter's 20 kHz pulse processing mechanism in the form of a common rectifier­-filter is completely eliminated. Data obtained from the test of a 3 kW feasibility model are ana­lyzed in support of presentation of the significant aspects of design and technology.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"92 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":"123537366","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}

However, due to the leakage inductances of transformer and the resistance components of the circuit, there appear the regulation errors in the cross-regulated outputs. This paper presents a new method to compensate the cross-regulation errors and regulate all of the multiple output voltages precisely. This precise regulation is performed by making use of an auxiliary switch in each output circuit, and therefore the additional power loss is not wasted in principle. Further, from the analysis of this new converter circuit, two different operation modes are clarified.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"175 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":"134168137","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}

Low weight and cost of apparatus is enhanced by the time proven reliability of its significant functional elements. The potential for the construction of megawatt capacity systems is derived from experience with the basic class of those converters and is reinforced by the report of reduction to practice of some of the described techniques in the form of a 3 kW model in a companion paper.","PeriodicalId":101593,"journal":{"name":"1979 IEEE Power Electronics Specialists Conference","volume":"72 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":"127280962","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}
