Criteria of efficiency of converters for such systems are distinguished, values of which are mainly determined by the choice of the inverter module. These criteria are used to compare main classes of inverter modules: current inverters, voltage inverters with multiple pulse width modulation and multilevel formation of the output curve. Formulated directions of improving inverters with a multilevel formation of the output curve allow to increase their competitiveness in comparison with inverters of other specified classes, when they used in autonomous power supply systems.","PeriodicalId":277559,"journal":{"name":"2020 International Conference on Actual Problems of Electron Devices Engineering (APEDE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132799557","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}
