Delay effects on the limit cycling behavior in an H-bridge resonant inverter with zero current switching control strategy
(2018)
Conference report
Open AccessIn 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 ... -
Sliding bifurcations in resonant inverters
(2017)
Conference report
Restricted access - publisher's policyIn this paper, the switching dynamics of a dc-ac resonant self-oscillating inverter is considered. Using bifurcation analysis coexisting steady-state solutions are predicted, which are increasingly ... -
Analysis of nonlinear and non-smooth dynamics of a self-oscillating series resonant inverter
(2017)
Conference report
Open AccessIn 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. Our system is defined by two symmetric configurations and its ... -
Efeito do dopante Ba sobre as propriedades estruturais e microestruturais de ceramicas Bi0.5Na0.5TiO3
(2015)
Conference report
Restricted access - publisher's policyRecently, Bi0,5Na0,5TiO3 (BNT) based ceramics has been widely studied as one promising material lead-free for piezoelectric applications. The Ba addition in BNT ((Bi0,5Na0,5)1-xBaxTiO3 - BNT-xBT) has attracted considerable ... -

Stability analysis of periodic orbits in a class of duffing-like piecewise linear vibrators
(EDP Sciences, 2014)
Conference lecture
Open AccessIn this paper, we study the dynamical behavior of a Duffing-like piecewise linear (PWL) springmass-damper system for vibration-based energy harvesting applications. First, we present a continuous time single degree of ... -
Preparation of top seeded YBa2Cu3O7 large single-domain tiles
(1997)
Conference lecture
Restricted access - author's decisionSingle domain superconductors with diameters up to 40 mm have been prepared by top seeding growth using Nd123 melt textured ceramics as seeds. We show that the use of these seeds is preferred over MgO single crystals to ... -
Fabrication of melt-textured cylinders and bars of (YBa2Cu3O7-Y2BaCuO5) superconductors
(1996)
Conference lecture
Restricted access - author's decisionCylinders and bars of bulk YBa2CuO7-Y2BaCuO5 textured ceramic composites (123-211) have been prepared through different directional solidification processes. Green ceramic preforms for the directional solidification process ... -
Sliding mode control of interconnected power electronic converters in DC microgrids
(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 ... -
