Bifurcation analysis in a self-oscillating series resonant converter
(De Gruyter Open Sp. z o.o., 2020-02-10)
Capítol de llibre
Accés restringit per política de l'editorialIn this paper, the dynamics of a dc-ac resonant self-oscillating LC series inverter is analyzed from the point of view of piecewise smooth dynamical systems. The system under study is defined by two symmetric configurations ... -
Centers of quasi-homogeneous polynomial differential equations of degree three
(2014-03-20)
Article
Accés restringit per política de l'editorialWe characterize the centers of the quasi-homogeneous planar polynomial differential systems of degree three. Such systems do not admit isochronous centers. At most one limit cycle can bifurcate from the periodic orbits of ... -
Counting configurations of limit cycles and centers
(2023-04-10)
Report de recerca
Accés obertWe present several results on the determination of the number and distribution of limit cycles or centers for planar systems of differential equations. In most cases, the study of a recurrence is one of the key points of ... -

Delay effects on the limit cycling behavior in an H-bridge resonant inverter with zero current switching control strategy
(2018)
Text en actes de congrés
Accés obertIn this paper, bifurcations of limit cycles in a H-bridge LC resonant inverter under a zero current switching control strategy with delay in the switching action are analyzed. Mathematical analysis and numerical simulations ... -
Delay effects on the limit cycling behavior in resonant inverters with state feedback
(2019-10-01)
Article
Accés restringit per política de l'editorialBifurcations of limit cycles in an H-bridge LC resonant inverter are reexamined taking into account a time delay in the switching transition. The analysis is accomplished by means of a model of the inverter that compresses, ... -
Dynamic analysis of self-oscillating H-bridge inverters with state feedback
(2020-01)
Article
Accés obertThis paper presents a comprehensive approach to analyze the dynamics of a generalized model of resonant inverters using nonsmooth dynamical system theory. The model simultaneously covers both parallel and series resonant ... -
In-depth analysis of smooth and nonsmooth bifurcations for an open-loop boost converter feeding constant power loads in discontinuous conduction mode
(2023-03-30)
Article
Accés obertThis paper presents a study of the existence conditions of limit cycles and mechanisms when losing their stability in an open-loop DC–DC boost converter loaded with a constant power load and operating in discontinuous ... -
Limit cycle bifurcations in resonant LC power inverters under zero current switching strategy
(2018-01)
Article
Accés obertThe dynamics of a DC-AC self-oscillating LC resonant inverter with a zero current switching strategy is considered in this paper. A model that includes both the series and the parallel topologies and accounts for parasitic ... -
Nonlinear dynamic modeling and analysis of self-oscillating H-bridge parallel resonant converter under zero current switching control: unveiling coexistence of attractors
(2018-12-14)
Article
Accés obertThis paper deals with the global dynamical analysis of an H-bridge parallel resonant converter under a zero current switching control. Due to the discontinuity of the vector field in this system, sliding dynamics may take ... -
On the 16th Hilbert problem for limit cycles on nonsingular algebraic curves
(2011-01-15)
Article
Accés restringit per política de l'editorialWe give an upper bound for the maximum number N of algebraic limit cycles that a planar polynomial vector field of degree n can exhibit if the vector field has exactly k nonsingular irreducible invariant algebraic curves. ... -
Structure of cycles and local ordering in complex networks
(Springer, 2004-03-01)
Article
Accés obertWe study the properties of quantities aimed at the characterization of grid-like ordering in complex networks. These quantities are based on the global and local behavior of cycles of order four, which are the minimal ... -
Suppression of undesired attractors in a self-oscillating H-bridge parallel resonant converters under zero current switching control
(2018-11-08)
Article
Accés obertResonant converters under zero current switching control strategy can exhibit coexistence of attractors, making it difficult the startup of the system from zero initial conditions. In this paper, the problem of multiple ...
