The switches turn on a zero current, and can use the thyristor-dual principle to virtually eliminate turn-off losses, an inherent advantage of the LVI topologies being a constant-frequency operation. A half-bridge LVI power-processing cell utilizing thyristor-dual switches is analyzed, its properties are discussed, and experimental results illustrating these properties are reported. It is demonstrated that the implementation is feasible and that it results in extremely low switching losses. The transient-stability problem inherent in topologies with thyristor-duals is discussed, and a simple and highly reliable solution is proposed. Steady-state analysis has been carried out, and the boundary of the fail-safe commutation of the switches is determined. The numerical results obtained can be directly incorporated into straightforward design programs; the design procedure is summarized in a comprehensive flowchart.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"21 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":"121202886","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 scheme can be regarded as a digital alternative of the analog subharmonic method (SHM) in the sense that online real-time PWM control is possible and synchronization between carrier wave and signal wave is unnecessary. The maximum output voltage is 15% larger and the number of switchings is 30% less than those obtained by SHM. The PWM pulse creation principle is explained. As the calculation of the optimal PWM pattern needs only three multiplications, it can be executed online with a minimum ROM capacity using a conventional microprocessor. Experimental results are reported demonstrating the validity of the proposed scheme.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"5 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":"134604172","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 application of the state-space averaging technique to the ICB circuit analysis is somewhat different from the well known DC-to-DC converter cases such as buck, boost, and flyback of Cuk converter analysis in that the first-order approximation of the state transition matrix will give trivial results. The results, which were previously obtained in infinite Fourier series form, are in closed form. A comparison is also made with the Fourier result. The ICB is a two-quadrant power supply for superconductive energy storage magnets. Closed-form expressions are found for the average current, voltage, and power behavior of the ICB. This application is somewhat different from the analysis of other DC choppers such as buck, boost, flyback, and Cuk converters in that the first-order terms are identically zero and the second-order terms have to be used.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"1 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":"128800378","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}
