Two circuits are reviewed in consideration: a Buck DC-DC converter and a resonant parallel-loaded inverter. The difference between the two circuits is only in the relationship between the switching frequencies and the resonant frequency. In the first case, the operating frequency is equal to the resonant, and in the other case, the control frequency significantly exceeds the resonant tank frequency (at least over 2-3 times). The main purpose of the manuscript is to present the influence of the tolerances of the resonant elements on the operating modes of devices that share the same topology. This way, an assessment is made of the dependence of the output indicators on the tolerances and, accordingly, how to look for solutions to ensure the output parameters.","PeriodicalId":178356,"journal":{"name":"2020 XXIX International Scientific Conference Electronics (ET)","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133924097","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}
