This proposed model is employed to simplify the mathematical formulation of the instantaneous as well as RMS currents of the converter, critically accountable for the system switching and conduction losses. Also, all the possible phase shift control methods, including single, dual, and triple phase shift modulations are rigorously studied and investigated in order to provide a generic and detailed insight on the applicability and benefits of using them on a wide range of gain and load demand while ensuring minimized conduction losses. A 400W proof-of-concept of DAB DC-DC converter has been developed to validate and establish the proposed frequency domain model-based theoretical analysis and claims. While the converter has a fixed input DC bus voltage of 160V, the output load power is varied within a range of 50W to 400W with a large swing in output voltage level, i.e., from 90V to 150V. With the implementation of the proposed optimal triple phase shift (TPS) control at extreme gain conditions, the experimental results show a system efficiency increment of 3.5% and 2.2 % compared to the conventional single-phase shift (SPS) modulation technique at 90V, 50W and 150V, 200W outputs, respectively.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131183989","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}

Through a combination the benefits of interlinking converter and switch, flexible transfer converters (FTCs), positioned at the interfaces between the utility grid and microgrids, are offered as a solution in this study. This paper proposes a control method for FTC and a universal control strategy for distributed generations, which contribute to proper power flow and flexible mode transfer in a communication-free design. They are convenient to control, easy to install based on existing assets, and hence promising in distributed microgrid applications. Also, an FTC for grid-connected microgrid system is analyzed and designed through small-signal modeling. Finally, comprehensive case studies in simulations and experiments are provided to validate its effectiveness.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127685206","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 SiC-based power semi-conductors can operate at higher switching frequencies with higher voltages and better stability than conventional silicon (Si) devices. Therefore, SiC-based power converters can achieve a high-power density. However, the high switching slew rate of SiC devices accompanied by high-speed switching operations can cause EMI noise problems. Conventional gate drivers cannot effectively control such EMI noise issues, including passive and active gate driver techniques under various system environments. This paper proposes an integrated active gate driver (AGD) to solve the EMI noise issues more effectively and flexibly. The proposed AGD controls the switching slew rate through controllable AGD voltages in real-time according to the system variables that can significantly affect switching characteristics such as the DC BUS voltage, output current, and device temperature. The proposed AGD enables switching devices to control the switching speed accurately under various system operational conditions. The proposed AGD method has been verified through experimental results.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116496090","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}
