Output voltage is controlled by proper selection of the switch modes, which is achieved by varying the duty ratio of the powering and free resonant modes. Each switch mode is analyzed and the DC transfer function obtained. Simulated and experimental results agree well. Advantages such as low current switching stress, low switching loss, low electromagnetic interference (EMI), high input power factor, and wide control range are obtained. Some of these characteristics are verified experimentally.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"12 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":"129595523","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}

Thus, exact measurement of both quantities for the relevant harmonics is theoretically possible. However, existing Z-transform estimation methods fail in such applications because of their sensitivity to the colored, nonGaussian noise present in most inverter topologies. An approach to Z-transform estimation is presented that is very insensitive to such colored noise. The approach is developed theoretically and experimental verified on a PC-AT-based signal acquisition system using actual inverter waveforms.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"359 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":"115894296","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}
