Resumo: Aiming to contribute to modulation strategies for converters with magnetically coupled parallel legs, a new strategy of discontinuous carrier modulation is developed for this class of converters. To clarify the strong points and limitations of the proposed modulation, an analysis between the discontinuous modulation and the phase shift carrier modulation with geometric approach is presented. Therefore, the synthesized multilevel equivalent output line voltage, the circulating currents between the parallel legs of the converter and the voltage and current THDs are investigated and compared in detail. First, the details of the geometric modulation for converters with parallel legs are presented. Next, the development of discontinuous carrier modulation by state machines is presented. The proposed modulation shows good results when compared to the phase shift carrier modulation strategy for interleaved converters. Experimental and simulation results show characteristics such as: (i) Limitation of circulating current; (ii) Reduction of THD of the output current; (iii) Reduction of current in switches; (iv) Reduction in the stress of the switching of switches; (v) Ease implementation are achieved by this modulation strategy.

Para esclarecer os pontos fortes e limitações da modulação proposta, foi estruturada uma análise entre a modulação descontínua e a modulação por deslocamento de fase com abordagem geométrica. Para tanto, a tensão de linha de saída equivalente sintetizada de vários níveis, as correntes circulantes entre as pernas paralelas do conversor e as THDs das tensões e correntes são investigadas e comparadas em detalhes. Primeiramente, são apresentados os detalhes da modulação geométrica para conversores com pernas paralelas. Em seguida, é apresentado o desenvolvimento de modulação descontínua com portadora por máquinas de estados. A modulação proposta apresenta bons resultados quando comparada com a estratégia de modulação por deslocamento de fase com portadora em conversores interleaved. Resultados de simulação e experimentais demostram que a estratégia de modulação proposta apresenta as seguintes características: (i) Possibilidade de limitação da corrente circulante; (ii) Reduzida THD da corrente de saída, sem comprometer a sua implementação; (iii) Reduzida THD de tensão de linha de saída; (iv) Redução do esforço de comutação dos interruptores; (v) Facilidade de implementação.porUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia ElétricaUFSMBrasilEngenharia ElétricaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessModulação descontínua com portadoraConversores interleavedControle de corrente circulanteModulação de conversoresPernas em paraleloDiscontinuous carrier modulationInterleaved converterCirculating current controlConverter modulationParallel legsCNPQ::ENGENHARIAS::ENGENHARIA ELETRICAModulação descontínua para conversores com pernas em paralelo magneticamente acopladasDiscontinuous modulation for converter with parallel legs magnetically coupledinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisPinheiro, Humbertohttp://lattes.cnpq.br/5900576762082210Carnielutti, Fernanda de Moraishttp://lattes.cnpq.br/3985702535358474Carvalho Júnior, Carlos Alberto Tenório dehttp://lattes.cnpq.br/2499599551388933Grigoletto, Felipe Bovolinihttp://lattes.cnpq.br/7906627505162145Farret, Felix Albertohttp://lattes.cnpq.br/5783619992936443Pinheiro, José Reneshttp://lattes.cnpq.br/2333794966860226http://lattes.cnpq.br/9613876404612535Ricciotti, Antonio Carlos Duarte3004000000076008aab6aac-f16b-4f23-8761-b8462475f0274d6b74c4-c02c-4886-8c4c-3de5f53f42c7afdd020f-c5be-4f2d-bdca-6882d625747d2ae39227-23a8-4392-a9eb-5cb3574f53e1e2fecd27-811e-4c76-85e6-af5c64d5b9c534475e46-7cb7-46a2-94f5-9fa6786991ee2e9a4591-cee9-4ca7-9e94-9a01328cdc8areponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALTES_PPGEE_2017_RICCIOTTI_ANTONIO.pdfTES_PPGEE_2017_RICCIOTTI_ANTONIO.pdfTese de Doutoradoapplication/pdf8600708http://repositorio.ufsm.br/bitstream/1/13372/1/TES_PPGEE_2017_RICCIOTTI_ANTONIO.pdfd1230924e63b97a89ab71920c83cb9dbMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

description Aiming to contribute to modulation strategies for converters with magnetically coupled parallel legs, a new strategy of discontinuous carrier modulation is developed for this class of converters. To clarify the strong points and limitations of the proposed modulation, an analysis between the discontinuous modulation and the phase shift carrier modulation with geometric approach is presented. Therefore, the synthesized multilevel equivalent output line voltage, the circulating currents between the parallel legs of the converter and the voltage and current THDs are investigated and compared in detail. First, the details of the geometric modulation for converters with parallel legs are presented. Next, the development of discontinuous carrier modulation by state machines is presented. The proposed modulation shows good results when compared to the phase shift carrier modulation strategy for interleaved converters. Experimental and simulation results show characteristics such as: (i) Limitation of circulating current; (ii) Reduction of THD of the output current; (iii) Reduction of current in switches; (iv) Reduction in the stress of the switching of switches; (v) Ease implementation are achieved by this modulation strategy.
