They change the operating area and define the low frequency characteristics. These effects are described together with their mathematical backgrounds. To optimize a resonant converter, e.g. to reduce the stresses and to improve the efficiency, the proper design of filter and energy storage components is also necessary, as well as the design of the resonant elements. As an example a zeo voltage switching multiresonant Cuk converter is investigated. It is shown that by shrinking the rating of the typical Cuk capacitor and by altering the winding ratios of the transformer and coupled inductor, the operating area will be improved.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130598899","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 study is applicable to boost, buck-boost, flyback, SEPIC, and Cuk topologies. The main conclusion is that the switching frequency variation range using a half-wave resonant switch is lower than that using a full-wave resonant switch if the load connected to the output is almost constant. Moreover, using topologies with a transformer (flyback, SEPIC or Cuk), this variation range can be minimized choosing an adequate value of the normalized switching frequency at the peak of the sinusoidal input voltage. However. this range increases greatly when the load changes in the same manner. In this case, a reduced switching frequency variation range is obtained using a full-wave switch. However, this type of resonant switch decreases the efficiency because it handles reactive energy, and then a trade-off between switching frequency variation range and efficiency must be considered.<<ETX>>","PeriodicalId":402706,"journal":{"name":"PESC '92 Record. 23rd Annual IEEE Power Electronics Specialists Conference","volume":"35 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133215474","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}
