However, GTO and antiparallel diode integration causes turn-off-capability degradation and undesirable GTO triggering by excess carriers flowing from the diode section. An isolation structure that uses a p-base grooving method and a selective lifetime control technique to solve this problem is investigated. A novel isolation structure that contains the drain region is also described. A high-power RC-GTO (4.5 kV, 1000 A) that is based on the optimized isolation structure is presented. The fabrication and electrical characteristics of the device are described.<<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":"123158962","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}

Because of the time-varying nature of such converters, the result is not very useful in gaining an insight into their dynamics. An analytical method that is based on the small-signal frequency response theory and the measurement approach is introduced to overcome this problem. The key idea is to use a signal which is formed by passing a continuous sinusoidal signal through a sample-and-hold circuit as the injected signal instead of the traditional continuous sinusoidal signal. Only the case in which the sampling frequency of the sample-and-hold circuit equals the switching frequency of the converter circuit is discussed.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"3 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":"115640350","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 results show that the dielectric loss constitutes a large part of loss at high frequency and that thermal runaway can occur unless some precautions are taken in the design. In particular, the amount of dielectric loss depends very strongly on the type of insulating materials used.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"51 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":"127555768","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 technique has been developed for eliminating sub and partial harmonics by ensuring that the output waveforms exhibit quarter-wave symmetry. Practical results demonstrate that the technique is successful. The effects that imposing quarter-wave symmetry has on other aspects of the modulator's performance are also considered.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"106 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":"122642391","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 can be used to improve utility system operation economics and system stabilities. The power-conditioning circuit interfacing an SMES and a utility network consists of thyristor or gate-turn-off (GTO) device bridges of the combinations of thyristor bridges and GTO bridges. The special requirements for power-conditioning circuits are discussed, and an experimental model system for testing the performance of the proposed circuits is described. The experimental studies concern power transfer of the model system, current balance control, independent real (P) and reactive (Q) power control, online numeric P-Q measurement, and protection of the SMES system. The proposed GTO circuit topology appears to satisfactorily provide independent real and reactive power control and maintain the high efficiency and fast response properties of the SMES system.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"55 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":"131290657","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}
