A Five-Level Common Grounded Boost Inverter Topology with Model Predictive Control for Grid-Tied Photovoltaic Generation
(IEEE Computer Society, 2021-10-13)
This paper presents a new common grounded (CG) multilevel boost inverter (MI) topology for single-phase grid-tied photovoltaic (PV) applications. The proposed topology has the capability to fully eliminate the leakage ...
A New Five-Level Grid-Connected PV Inverter Topology Controlled By Model Predictive
(IEEE Computer Society, 2022)
The transformer-based inverters in PV systems increase the weight, size, and cost of the inverter while reducing efficiency. This research presents a new PV inverter topology to increase efficiency using a reduction of ...
Model Predictive Control for An Improved Transformer-less Five-level PV Inverter Topology
(Institute of Electrical and Electronics Engineers Inc., 2022)
Power inverters have been located at the heart of photovoltaic (PV) applications. Transformer-less inverters possess several benefits over transformer-based PV inverters such as low volume, low cost, and higher effectiveness ...
Five-level cascade asymmetric multilevel converter

Desenvolvimento de conversores de cinco níveis com capacitor chaveado e grampeamento ativo do ponto neutro
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2022-06-28)
This work aims to propose a five-level converter topology. The proposed converter
uses the switched capacitor concept with an active neutral point clamped structure, with
one floating capacitor per phase and only one ...
Structural and electronic transformations upon heating of the topological insulator Bi2Se3
(Universidade Federal de Minas GeraisUFMG, 2017-03-15)
Bismuth Selenide (Bi2Se3) is a topological insulator compound with a lamellar structure formed by the repetition of stacks of five atomic monolayers, each of them consisting of layers with either Se or Bi atoms. Each ...

Stratifying the potential local transmission of Zika in municipalities of Antioquia, Colombia
(Blackwell Publishing Ltd, 2017-10-01)
OBJECTIVE To stratify and understand the potential transmission processes of Zika virus in Colombia, in order to effectively address the efforts on surveillance and disease control. METHODS We compare R-0 of Zika for ...
A search for C-H···O type hydrogen bonds in Lamivudine (3TC). An exploratory conformational and electronic analysis
(Elsevier Science, 2001-06-22)
A conformational study of the molecule Lamivudine (3TC), or cis-1-[2′-hydroxymethyl-5′-(1,3-oxathiolanyl)] cytosine, was carried out. Rotation about the C-N bond (φ1) and about the C-CH2(OH) bond (φ2), which connects the ...
