This, however, must be paid for with a relatively high voltage stress across the switch causing problems when the converter is operated from the mains. A 500 kHz 21 W electronic lamp ballast for 220 V mains is presented. A cascoded BIMOS incorporating a TV deflection transistor combines rapid switching with the required excessive voltage capability for mains drive. An excellent efficiency of 93% could be achieved.","PeriodicalId":153760,"journal":{"name":"1985 IEEE Power Electronics Specialists Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132151230","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 input filter has a general form including any number of harmonic traps. In addition, the characteristics of the converter gating circuit are also simulated. The set of equations derived in this paper are valid for all modes of operation of the bridge converter including single and double commutation periods, freewheeling period, and operation under faulty conditions. The method is used for the steady state, transient and fault studies. Several examples illustrating the applications of the simulation method are included. The experimental results are used to verify the accuracy of the simulation method.","PeriodicalId":153760,"journal":{"name":"1985 IEEE Power Electronics Specialists Conference","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126252543","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}

In the same type of converters made public recently, which use two six-pulse fully-controlled bridge rectifiers, high frequency current pulses must be fed to load tank circuit through two thyristor switches in series. But in the system presented here, each pulse flows through either one switch or parallel two switches, so that it is expected to provide good efficiency with the advantage of a small parts count. Features inherent in this type of converter such as stable operation, high power factor and low harmonics are also maintained. The operation of the circuit along with circuit parameter requirements are described using a simplified model of the converter.","PeriodicalId":153760,"journal":{"name":"1985 IEEE Power Electronics Specialists Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115903377","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}
