Bifurcation analysis in a self-oscillating series resonant converter
Ponce, Enrique; Benadero García-Morato, Luis; El Aroudi, Abdelali (De Gruyter Open Sp. z o.o., 2020-02-10)
Part of book or chapter of book
Restricted access - publisher's policyIn 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 ... -
Bifurcation analysis of a DC–DC bidirectional power converter operating with constant power loads
Cristiano, Rony; Pagano, Daniel J.; Benadero García-Morato, Luis; Ponce, Enrique (2016-04)
Article
Open AccessDirect current (DC) microgrids (MGs) are an emergent option to satisfy new demands for power quality and integration of renewable resources in electrical distribution systems. This work addresses the large-signal stability ... -
Delay effects on the limit cycling behavior in resonant inverters with state feedback
Benadero García-Morato, Luis; El Aroudi, Abdelali; Ponce, Enrique (2019-10-01)
Article
Restricted access - publisher's policyBifurcations 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, ... -
Limit cycle bifurcations in resonant LC power inverters under zero current switching strategy
Benadero García-Morato, Luis; Ponce, Enrique; El Aroudi, Abdelali; Torres Peral, Francisco (2018-01)
Article
Open AccessThe 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 analysis of interconnected power converters: a case study
Benadero García-Morato, Luis; Cristiano, Rony; Pagano, Daniel J.; Ponce, Enrique (2015-09-01)
Article
Open AccessIn this paper the nonlinear dynamics of interconnected power converters in an islanded direct current (DC) microgrid is analyzed. By using a simplified scheme based on two cascaded converters we analyze the dynamical ... -
Nonlinear dynamic modeling and analysis of self-oscillating H-bridge parallel resonant converter under zero current switching control: unveiling coexistence of attractors
El Aroudi, Abdelali; Benadero García-Morato, Luis; Ponce, Enrique; Olalla Martinez, Carlos; Torres Peral, Francisco; Martínez Salamero, Luis (2018-12-14)
Article
Open AccessThis 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 ... -
Sliding mode control of interconnected power electronic converters in DC microgrids
Stramosk, Vinicius; Benadero García-Morato, Luis; Pagano, Daniel J.; Ponce, Enrique (2013)
Conference lecture
Restricted access - publisher's policyIn this work, a typical structure of cascaded converters present in DC microgrids is analyzed. From the control point of view, converters acting as loads add a nonlinear effect to the supply bus, caused by its constant ... -
Suppression of undesired attractors in a self-oscillating H-bridge parallel resonant converters under zero current switching control
El Aroudi, Abdelali; Benadero García-Morato, Luis; Ponce, Enrique; Olalla Martinez, Carlos; Torres Peral, Francisco; Martínez Salamero, Luis (2018-11-08)
Article
Open AccessResonant 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 ...
