Desenvolvimento de um sistema de baixo custo para monitoramento remoto do consu...
Aquino, André Teixeira de; Almeida, Bruno Ricardo de; Guimarães, Jéssica Santos; Pacheco, Juliano de OliveiraIn order to facilitate the monitoring of electric energy consumption, the present paper presents the development of a low cost system, with mobile device interface, capable of measuring the active power consumed by electric charges and calculat-ing the energy consumed by them. To measure the active power demanded by the load, the system uses the ESP8266 NodeMCU module, connected to an MCP 3909 energy analyzer C...

Santos, Kristian Pessoa dos; Santos, Cícero Alisson dos; Bascopé, René Pastor Torrico; Praça, Paulo Peixoto; Almeida, Bruno Ricardo deThe converters CA-CC are a most used converters in industry and be present in practically all electronic devices, illumination systems, laptops, biomedical equipment and others. However, this converter behaves as nonlinear load to electric system and producing a non-linear current and have high value of Total Harmonic Distortion (THD). To around this issue, the Power Factor Correction (PFC) is made using dedica...
Modelo equivalente e controle digital de um conversor CC-CC boost intercalado c...
Chaves, Breno Bezerra; Brito Júnior, Francisco José Barbosa de; Damasceno, Debora Pereira; Almeida, Bruno Ricardo de; Bascopé, René Pastor TorricoThis work presents a methodology for modeling and designing the digital control of a DC-DC Boost converter with high voltage gain based-on the three-state switching cell (TSSC). The control strategy adopted is the averaged current mode control with four internal current loops, one for each phase of the TMIFs (Multi-Interphase Transformer), which receive the same reference signal coming from an external voltage ...
Conversor monofasico multiportas aplicado a microgeração residencial
Barbosa, Samanta Gadelha; Almeida, Bruno Ricardo de; Pacheco, Juliano de Oliveira; Oliveira Júnior, Demercil de SouzaThis paper presents a multi-port single-phase isolated converter applied to a residential microgeneration, with one port in alternate current (AC) and anothers in direct current (DC). It's main characteristics, operating steps and working modes are presented. The results are obtained through simulation for a AC voltage of 220 V and voltage on DC ports of 400 V, 96 V and 48 V, switching frequency of 50 kHz and 1...
Avaliação da percepção do aluno de Engenharia com relação aos principais Teorem...
Almeida, Bruno Ricardo de; Guimarães, Jéssica Santos; Oliveira, Átila Girão de; Jaguaribe, Daniel Rebouças; Paz Filho, Mauro Cezar PereiraKnowing the great importance of the competence development of the knowhow of analyzing and designing electrical circuits in the engineering courses that involve electricity (such as Electrical Engineering, Electronic Engineering, Control Engineering and Automation, among others), this article aims to perform a research to identify the difficulties encountered by students in applying the main theorems and method...
Conversor CA-CC trifásico de único estágio, bidirecional, isolado em alta frequ...
Almeida, Bruno Ricardo deThis work proposes the study and implementation of a single-stage three-phase bidirectional ac-dc converter with high-frequency isolation and power factor correction. Based on the dual active bridge (DAB) converter associated with the three-state switching cell (3SSC), it is possible to state that this topology is adequate for telecom power supply applications operating at 380 V-400 V. Another interesting appli...
Sistema de controle digital para WECS de eixo vertical
Almeida, Bruno Ricardo deAn option to minimize the energetic problems using renewable energy sources is the distributed micro generation in urban areas. In this kind of environment, where the winds are not regular ande turbulent, the efficiencies from vertical axis wind turbines are comparable to those ones from horizontal axis wind turbines, with the additional vantage of producing low mechanical vibrations at low rotation speeds.
