The gating pulse pattern of the converters is chosen so that no circulating current flows between the converters when they are operated simultaneously. A good input power factor is obtained with less ripple in the output current. A symmetrical type of gating is worked out in which all the GTOs in the converter are switched an equal number of times during each cycle of the source voltage. The motor current is free to reverse naturally at any moment, hence discontinuous conduction of the motor current can not occur. A four-quadrant closed-loop speed-controlled DC motor drive fed from the proposed dual converter has been designed, constructed, and tested. The experimental results obtained are shown to be in good agreement with theory.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114704219","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 provides flexibility in choosing the settling time, the profile of the response of the system, and the order of the controller. The algorithm is very simple and fast. Good results have been achieved even when the plant has an unstable zero. The technique is extremely useful in matching the performance of the servos in a multiaxis motion control system to minimize path errors.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124727943","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 circuits are current-source rectifiers, so that suppressing the overvoltage on the GTOs during commutation is an important consideration. Moreover, to get high conversion efficiency it is necessary to handle the commutation energy properly. Two circuits are presented for this purpose, and the detailed computer simulation of these circuits is discussed. The resulting design policies and characteristics for both circuits are described, and the best choice of converter circuit for SMES is determined.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123159330","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 energy emanates from a source (single of polyphase voltage source generating unipolar of bipolar waveforms), and is transmitted to a network (load) in a specific form (unipolar or bipolar, single or polyphase voltage waveforms). A discussion of the stability of the energy transfer in relation to the excitation voltage leads to a clarifying description of the possibilities for the control of the resonant energy transfer for any conversion ratio. A control strategy is applied to adapt the characteristics of the resonant circuit to the rapidly varying voltages. The results of a simulation program, developed particularly for this class of conversion systems, confirm the processes.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"295 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123181477","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}

An easy and elegant approach to the synthesis of optimal discrete pulse modulation waveforms is presented. Utilizing the finiteness of the set of possible waveforms, an exhaustive search algorithm is deployed to derive a set of optimum waveforms simultaneously satisfying specified fundamental voltage constraints and cost functions. For frequency ratios of up to around 80, the technique is tractable and gives excellent results. For aerospace applications with 400 Hz outputs, which result in frequency ratios of 50 for 20 kHz link frequency, the strategy results in substantially higher levels of performance. For larger frequency ratios of 100-2000, typical of industrial resonant link inverter drive systems, this technique requires unworkably high computation times. A suboptimal limited search technique is proposed with reasonable performance characteristics is proposed for this case.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127302058","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}
