Tri-state Space Vector Modulation for Three-phase integrated inverters
(2011-12-28)
The aim of this work is to present a modified Space Vector Modulation (SVM) suitable for Tri-state Three-phase inverters. A standard SVM algorithm and the Tri-state PWM (Pulse Width Modulation) are presented and their ...
Uma introdução aos espaços vetoriais topológicos
(Universidade Estadual Paulista (Unesp), 2021-01-21)
Neste trabalho estudamos os espaços vetoriais topológicos e suas propriedades. Para isso utilizamos como referências principais [1] e [2]. A primeira mais voltada ao estudo da Topologia Geral e a segunda ao estudo dos ...

On the Norm with Respect to Vector Measures of the Solution of an Infinite System of Ordinary Differential Equations
In the present paper we give some necessary conditions that satisfy the solutions of an infinite system of ordinary differential equations. We investigate the behavior of the solutions of a general system of equations, ...

Unit vectors are dimensionless vectors having a magnitud of 1. Unit vector are used to specify a given direction and have no other physical significance. They are used only in describing a direction in space. We shall use ...
Generalized interval vector spaces and interval optimization
(Elsevier B.V., 2015-08-01)
This paper presents a method for endowing the generalized interval space with some different structures, such as vector spaces, order relations and an algebraic calculus. With these concepts we formulate interval optimization ...
Modulação Space Vector ótima para conversores estáticos
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2019-06-03)
This work proposes an optimal space vector modultation methodology based on the FCSMPC
approach for static converters relying on a cost function in order to decide, among
the redundant vectors, those which forms the ...
Sliding Vector Fields via Slow-Fast Systems
(Belgian Mathematical Soc Triomphe, 2008-01-01)
This paper concerns differential equation systems on R(n) with discontinuous right-hand sides. We deal with non-smooth vector fields in R(n) having a codimension-one submanifold M as its discontinuity set. After a ...
