Conversor trifásico bidirecional de três níveis com alto fator de potência para...
Reis, Francisco Everton Uchôa; Bascopé, René Pastor Torrico; Costa, Marcus Vinicius SilvérioThis paper proposes a bidirectional three-phase and three-level converter (3L-SNPC) and proposes its application to a charging station for electric vehicles. The proposed converter is capable of operating at high power factor either as a DC-to-AC converter or as an AC-DC converter employing the same control and modulation strategy. The converter has the advantages of providing three voltage levels in each leg, ...
Análise e simulação do controlador MPC-AW-LMI aplicado ao conversor CCTE operan...
Rego, Rosana Cibely Batista; Costa, Marcus Vinicius Silvério; Reis, Francisco Everton Uchôa; Bascopé, René Pastor TorricoThis paper proposes a model predictive control with anti-windup (AW) atuator optimized via linear matrix inequalities (LMIs) approach applied to three state switching cell (3SSC) boost converter operating in saturation mode. This work are shown a state space converter model, besides the proposition and test of MPCAW-LMI control strategy applied to numerical model of converter and compared with MPC-LMI control e...
Controle digital backstepping para spmp aplicado em sistema fotovoltaico
Silva, Robson Taveira Gonçalves da; Veras, Caio Kerson Oliveira; Costa, Marcus Vinicius Silvério; Freitas, Antônio Alisson AlencarA energia solar pode ser transformada em energia elétrica com o uso de sistemas fotovoltaicos, entretanto a eficiência desta conversão nestes sistemas depende, em grande parte, de condições ambientais, comoa variaçãoda irradiação e temperaturaambiente. Portanto este trabalho propõe o desenvolvimento de um algoritmo, através de simulação computacional,para o seguimento dos pontos de máxima de potência-SPMP(Maxim...
Controle MPC robusto aplicado ao conversor Boost CCTE otimizado por inequações ...
Costa, Marcus Vinicius SilvérioThis work proposes a MPC predictive control strategy applied to a three-state switching cell boost (3SSC) converter that gives more simplicity and systematization to the control design steps and analysis. The integral gain controller can adjusted, eliminating the re-design the weighting matrices. Besides, the stability elipsoid theory are used to simplify the stability analysis of converter. The proposed MPC be...

Costa, Marcus Vinicius SilvérioThis work involves the application of robust controls D-LQI and D-pole placement via LMIs in a high-gain boost with three states switching cell. This converter consists of a modern topology derived the classic boost converter . This boost converter is considered a step-up converter, which a range of 4254V voltage input to 400V voltage output. The proposed boost converter is reduced to equivalent model and is mo...
