This system has to convert a 1-phase ac or a dc voltage into a 3-phase 50 or 60 Hz voltage. This paper presents solutions built on power electronics. Compared to rotating equipment the power electronic solution offers important advantages regarding weight, losses and mechanical flexibility. The transient behaviour at pantograph bounces and switching in the load is also dealt with.","PeriodicalId":227481,"journal":{"name":"1980 IEEE Power Electronics Specialists Conference","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134101941","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 system consists of a regulated switching dc-to-dc converter, a solar-cell-array simulator, a solar-array EMI filter, battery chargers and linear shunt regulators. Loss mechanisms in the converter power stage, including switching-time effects in the semiconductor elements, are incorporated into the modeling procedure to provide an accurate representation of the system without requiring frequency-domain measurements to determine the damping factor. The small-signal system model is validated by the use of special measurement techniques which are adapted to the poor signal-to-noise ratio encountered in switching-mode systems. The complete electrical power system with the solar-array EMI filter is shown to be stable over the intended range of operation.","PeriodicalId":227481,"journal":{"name":"1980 IEEE Power Electronics Specialists Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122181831","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 inverter employs a high frequency dc-chopper for shaping the output current, providing unity power factor operation and minimizing the size of the output filter. The isolation of the solar array from the utility is accomplished with a high frequency transformer, eliminating the need for large, 60 Hz magnetics. The dynamics of the power circuit are analyzed to determine proper compensation of the output current control loop. This analysis shows that a minor loop is required to stabilize the power circuit and that system response varies during the 60 Hz cycle. A Parity Simulation of the power circuit/control system is performed to verify this analysis. The results of this simulation are presented and compared to waveforms from a test inverter. The special considerations required for properly loading a photovoltaic array with a line interfaced inverter are discussed.","PeriodicalId":227481,"journal":{"name":"1980 IEEE Power Electronics Specialists Conference","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116236858","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}
