It is confirmed that the LC constants can be determined by using a simple circuit model, and that setting a low resonant capacitor voltage is effective for reducing the main circuit loss.

This system used a dumping resistor for protection, but the stored energy in the magnet was successfully transferred back to the power line by the phase control operation of the thyristor converter in the dummy quenching test. Operation in the permanent-current mode was also verified, and the decay time of the permanent current was consistent with loss due to the forward voltage drop of the thyristor switch.<<ETX>>","PeriodicalId":283605,"journal":{"name":"PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference","volume":"118 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":"125028636","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.

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}
