Resumo: | This work contains the study of basic topologies of hybrid converters classified as serious impedance, the converters presented here are said to be hybrid because they associate two technologies, the switched converters and the linear amplifiers, the objective here is to extract the best in each structure, to get from amplifiers responses with high speed and without distortion (high fidelity) and from switched converters the ability to bring greater energy density to the load. There are several ways to associate both Technologies. The switched converter, the load and the linear amplifier can be placed in parallel or in series, the linear amplifier may or may not have a power source, when the amplifier does not have a power source, linear uses energy from the switched converter. This dissertation deals with a series association and with the sourceless linear amplifier, with these characteristics the linear amplifier can be observed as an impedance. A general study carried out on both technologies is presented. On the MOSFET amplifiers, the characteristics (structure, form of construction and the physical phenomena present), the forms of operation (operation points such as cuts, triode and saturation, identifying at this moment what is the linear region and how to maintain the operation in this region), the limitations (such as threshold voltage, capacitive and resistive couplings and the dependence of the gain in relation to the drain current) and finally a methodology for projects of MOSFET amplifiers controlled by operational amplifiers. The design of each of the hybrid converters is demonstrated followed by an analysis carried out through the simulations responses, at the end the experimental design is presented, for which the Buck converter was chosen, then an analysis of the results of this experiment follows. |

Existem algumas formas para associar ambas as tecnologias. O conversor chaveado, a carga e o amplificador linear, podem ser colocados em paralelo ou em série, o amplificador linear pode ainda possuir ou não fonte de energia, quando não possui fonte de energia o amplificador linear utiliza a energia provinda do conversor chaveado. Essa dissertação trata de uma associação série e com o amplificador linear sem fonte, com essas características o amplificador linear pode ser observado como uma impedância. Um estudo geral realizado sobre ambas as tecnologias associadas é apresentado. Sobre o amplificador a MOSFET, são apresentadas as características (estrutura, forma de construção e os fenômenos físicos presentes), as formas de operação (pontos de operação como cortes, triodo e saturação, identificando nesse momento qual é a região linear e como manter a operação nessa região), as limitações (como tensão de limiar, acoplamentos capacitivos e resistivos e a dependência do ganho em relação a corrente de dreno) e por fim é apresentada uma metodologia para projetos de amplificadores a MOSFET controlados por amplificadores operacionais. O projeto de cada um dos conversores híbridos é demonstrado seguido de uma análise realizada através das respostas de simulações, no fim é apresentado o projeto experimental, para esse foi escolhido o conversor Buck, segue-se uma análise dos resultados desse experimento.Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de TecnologiaPinheiro, José Reneshttp://lattes.cnpq.br/2333794966860226Vidor, Dalton Luiz RechBisogno, Fábio EckeCunha, Vagner Maciel2022-05-30T17:37:54Z2022-05-30T17:37:54Z2022-03-16info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/24586porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2022-05-30T17:37:54Zoai:repositorio.ufsm.br:1/24586Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-05-30T17:37:54Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
