Three-phase half-controlled boost converter operating in quasi-critical conduction mode
(2019-01-25)
AC-DC converters, which operate in discontinuous conduction mode, can be used as power factor correction. Operating with constant duty cycle, the control system presents low complexity, however, for low static voltage ...
Three-phase Half-controlled Boost Converter Operating in Quasi-critical Conduction Mode
(Ieee, 2018-01-01)
AC-DC converters, which operate in discontinuous conduction mode, can be used as power factor correction. Operating with constant duty cycle, the control system presents low complexity, however, for low static voltage ...
Applying a new methodology to verify transmission line model performance - the equivalent impedance test
(IEEE, 2001-01-01)
The objective of this paper is to present a methodology to analyze a transmission line model used in electromagnetic transitory simulators, called equivalent impedance test. Initially the definition of equivalent impedance ...
Controlador MRAC-SM aplicado a um conversor QUASI-Z-SOURCE fotovoltaico conectado à rede monofásica
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2019-08-02)
This dissertation deals with the design and development of an Adaptive Control by Model
Reference (MRAC) structure together with a Sliding Mode (SM) controller through a simplified
first order reference model, neglecting ...
Compact modes in quasi one dimensional coupled magnetic oscillators
(IOP Publishing Ltd., 2017)
In this work we study analytically and numerically the spectrum and localization properties of three quasi-one-dimensional (ribbons) split-ring resonator arrays which possess magnetic flatbands, namely, the stub, Lieb and ...

The stationary instability in quasi-reversible systems and the lorenz pendulum
(2001)
We study the resonance at zero frequency in presence of a neutral mode in quasi-reversible
systems. The asymptotic normal form is derived and it is shown that in the presence of a
reflection symmetry it is equivalent to ...
