Metodologia de projeto de conversores integrados aplicando técnicas de redução de capacitâncias em drivers de LED
(Universidade Federal de Santa Maria, 2023-09-29)
This work presents a methodology for the design and analysis of integrated converters, using
buck, boost and buck-boost topologies operating in discontinuous conduction mode, as power
factor correction and power control ...
Controle hierárquico para inversores formadores de rede em microrredes AC
(Universidade Federal de Santa Maria, 2023-12-14)
This work presents the operating modes of a medium voltage Microgrid, addressing
hierarchical control with a focus on primary and secondary control. In primary control,
current control, voltage control, virtual impedance ...
Metodologia para identificação de crescimento microbiano em tempo real empregando técnica de medição não invasiva
(Universidade Federal de Santa Maria, 2023-07-28)
This thesis discusses the creation of a new methodology for the real-time, non-invasive monitoring of microbial growth in food microbiology. In the face of the complexity and time required by conventional microbiological ...
Metodologia de modulação space vector ótima aplicada a conversores estáticos
(Universidade Federal de Santa Maria, 2023-12-13)
Power converters are main components in many electrical systems. They are composed by
semiconductors switches that operate in relatively high frequency compared with the ones
of interest in order to synthesize the required ...
Fonte ininterrupta de energia de dupla conversão com integração de energia fotovoltaica
(Universidade Federal de Santa Maria, 2024-03-02)
This work presents topologies and designs for the integration of photovoltaic systems with
a double-conversion uninterruptible power supply (UPS). Based on the literature review,
two topologies are derived and selected ...
Análise técnica e de custo-benefício do sistema não convencional trifásico a dois fios para a distribuição de energia elétrica em média tensão no meio rural
(Universidade Federal de Santa Maria, 2024-03-14)
This Doctoral Thesis presents a technique to support the hypothesis that the Three-Phase Two-
Wire (TPTW) system is an excellent economic alternative for rural properties that do not have
their electricity needs met by ...
Metodologia de projeto otimizado de filtros de entrada e saída de fontes ininterruptas de energia: volume, perdas e tempo de vida
(Universidade Federal de Santa Maria, 2024-02-20)
In this work are developed design methodologies for LCL and LC filters, considering
their impact on the entire system. The proposed methodology seeks, through a parametric
sweep, to obtain the optimal design points for ...
Impacto das mudanças climáticas nos atuais sistemas fotovoltaicos e projeções de longo prazo
(Universidade Federal de Santa Maria, 2024-04-12)
This thesis presents some proposals related to climate change that can influence photovoltaic systems and, possibly, infer the influence of solar cycles on their performance. Projections of these climate changes were carried ...
