Journal ArticleDOI
Interleaved-Boost Converter With High Voltage Gain
Gustavo Alves de Lima Henn,R. N. A. L. Silva,Paulo P. Praca,Luiz H. S. C. Barreto,Demercil S. Oliveira +4 more
TL;DR: In this article, an interleaved-boost converter, magnetically coupled to a voltage-doubler circuit, is presented, which provides a voltage gain far higher than that of the conventional boost topology.
Journal ArticleDOI
A quasi-resonant quadratic boost converter using a single resonant network
Luiz H. S. C. Barreto,Ernane Antônio Alves Coelho,Valdeir J. Farias,J.C. de Oliveira,L.C. de Freitas,J.B. Vieira +5 more
TL;DR: According to the simulation and experimental results, this quadratic boost converter provides a larger conversion ratio than that provided by the conventional boost converter (for a given duty ratio D), and presents optimum performance, which operates with soft-switch commutation using a single resonant network.
Journal ArticleDOI
High-Voltage Gain Boost Converter Based on Three-State Commutation Cell for Battery Charging Using PV Panels in a Single Conversion Stage
TL;DR: In this paper, a three-state commutation cell for battery charging using PV panels and a reduced number of conversion stages is presented, which operates in zero-voltage switching (ZVS) mode for all switches.
Journal ArticleDOI
Soft switching high-voltage gain dc-dc interleaved boost converter
Ranoyca Nayana Alencar Leão e Silva Aquino,Fernando Lessa Tofoli,Paulo P. Praca,Demercil de Souza Oliveira,Luiz H. S. C. Barreto +4 more
TL;DR: This study presents the qualitative and quantitative analyses, design procedure and experimental results on a soft switching cell applied to a high-voltage gain interleaved boost converter with main advantages of a hard switching topology.
Journal ArticleDOI
ICA feature extraction for the location and classification of faults in high-voltage transmission lines
Aryfrance Rocha Almeida,Otacílio da Mota Almeida,Bartolomeu Ferreira dos Santos Junior,Luiz H. S. C. Barreto,Allan Kardec Barros +4 more
TL;DR: In this article, the authors proposed an approach by combining independent component analysis (ICA) with travelling wave theory and support vector machine (SVM) to locate and recognize faults in highvoltage (HV) transmission lines, while the acquired signals are noisy.
