If the filtering out is not strictly performed, the AC input current of each module is affected with the appearance of non-characteristic harmonics, sub-harmonics or inter-harmonics; thus, the RMS currents in the multi-pulse transformer secondaries increases. This problem may become even more evident if the converter output frequency is lower than the AC mains frequency, because the capacitor presents higher impedance at low frequency, causing that part of the harmonic currents demanded by the inverter is supplied directly by the rectifier. This paper presents an alternative to eliminate the unexpected harmonics and thus reduce the RMS values of the power cells input current in cascaded multilevel converters. The proposed solution uses magnetic couplings between the power modules of the converter; such approach is presented as a low cost solution compared to the conventional oversized DC-link capacitors.","PeriodicalId":196284,"journal":{"name":"IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114979184","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 research conducted so far includes various aspects pertinent to the topology, such as different inverter topologies connected to each side of the stator winding, different ratios of dc-bus voltages, operation with differing switching frequencies of the two inverters, comparison of performance with equivalent single-sided supply topologies, etc. In vast majority of cases supply of inverters at the two sides of the winding is provided from isolated dc sources. This paper investigates for the first time a five-phase open-end winding topology, which is obtained by connecting a two-level five-phase inverter at each side of the stator winding and supplying both inverters from a common dc source. In such configuration it is essential to eliminate the common-mode voltage (CMV) that is inevitably created by usual PWM techniques. Based on established criteria, the switching states that create zero CMV are indentified and plotted, giving a space vector pattern that is characterized with large redundancy of switching states. Suitable space vectors are selected to realize the required voltage reference at the machine terminals with zero CMV. The large number of redundant states enables some freedom in choice of switching states to impress these space vectors. Out of numerous possibilities, two particular switching sequences are chosen for further investigation. Both are simulated and also implemented in an experimental rig, and the results are presented.","PeriodicalId":196284,"journal":{"name":"IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society","volume":"28 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121005765","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}
