Generalization of Wye and Delta auto-connections: Analysis of voltages and currents
(2010-12-01)
Multipulse rectifier topologies based on autoconnections, or differential connections, are more and more applied as interface stages between the mains and power converters. These topologies mitigate many low-order current ...
Nilsequences and a structure theorem for topological dynamical systems
(ELSEVIER, 2010)
We characterize inverse limits of nilsystems in topological dynamics, via a structure theorem for topological
dynamical systems that is an analog of the structure theorem for measure preserving systems. We
provide two ...
Superconductivity in a topological weyl semimetal
(2024)
In this work, we determine the possible superconducting states produced in a type-I Weyl semimetal under a generic interaction, according to the topological nature of the Cooper pair. Once identified, we study the competition ...
Asymmetrical 17-Level Inverter Topology with Reduced Total Standing Voltage and Device Count
(2021)
Voltage source Multilevel Inverters (MLIs) are vital components for medium voltage and high-power applications due to their advantages like modularity and better power quality. However, the number of components used is ...
Traces in symmetric monoidal categories
(Medellín - Ciencias - Maestría en Ciencias - MatemáticasEscuela de matemáticasUniversidad Nacional de Colombia - Sede Medellín, 2019-09-13)
The objective of this work is to generalize basic ideas from linear algebra and topology, such as traces and fixed points, into a categorical context. Each of those generalizations has important objects and ideas behind, ...
Fault-Tolerant inverter for Power Flow Control in Variable-Speed Four-Wire Permanent-Magnet Generators
(Institute of Electrical and Electronics Engineers, 2015-11)
A strategy for fault detection and tolerance on the inverter that controls power flow in variable-speed permanent-magnet generators is proposed in this paper. The performance of the proposed strategy is analyzed in two ...
Classes características de variedades topológicas e generalizadas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2022-03-24)
In this work, we will initially present generalized bundles, a concept developed by Fadell with
the objective of generalizing vector bundles, Stiefel-Whitney classes andWu’s formula from the
context of smooth manifolds ...
Modeling and control of emerging DC-DC topologies for renewable energy applications
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2021-06)
The main topic in this dissertation is the penetration of renewable energy into the grid, since it has been increasing considerably over the years. In this topic, it is involve the study of DC-DC and DC-AC power conversion. ...
