A space vector algorithm suitable for this PRDCL inverter is presented. The algorithm eliminates narrow PWM pulses which impede DC link operation.

Based on the small-signal analysis, the design procedure for the current and voltage error amplifiers is shown in detail. The system relative stability is investigated to ensure that the performance requirements are satisfied. It is pointed out that the loop-gain function in a multiple-loop system is not as useful as that in a single-loop system. In other words. the current and voltage error amplifiers or compensators need to be selected based on the system characteristic equation, which is uniquely defined for a system.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126129933","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}
