Effect of heat input in Fe-based nanostructured weld overlay
(Taylor & Francis, 2015-11)
In the last few years, several welding consumables have been developed that deposit hard iron-based nanostructured alloy coverings with high resistance to abrasive wear. The erosive and abrasive wear resistances are mainly ...
Novel high-power-factor ZCS-PWM preregulators
(Institute of Electrical and Electronics Engineers (IEEE), 2001-04-01)
This paper introduces novel zero-current-switching (ZCS) pulsewidth-modulated (PWM) preregulators based on a new soft-commutation cell, suitable for insulated gate bipolar transistor applications. The active switches in ...
Current controller for a bidirectional boost input stage equipped with an LCL (inductance-capacitance-inductance) filter
(Elsevier, 2015-05)
A control strategy for a low resonance frequency LCL filter used in the input stage of dc-dc bidirectional boost converters is proposed. When compared with the classical L filter, an LCL filter allows to obtain a cheaper ...
Voltage-oriented input-output linearization controller as maximum power point tracking technique for photovoltaic systems
(Institute of Electrical and Electronics Engineers, 2015-06)
This paper presents a robust input-output linearization controller as maximum power point tracking (MPPT) technique in a photovoltaic (PV) buck dc-dc converter with applications to dc microgrids, solar vehicles, or stand-alone ...
Input normalization by global feedforward inhibition expands cortical dynamic range
(Nature Publishing Group, 2009-11)
The cortex is sensitive to weak stimuli, but responds to stronger inputs without saturating. The mechanisms that enable this wide range of operation are not fully understood. We found that the amplitude of excitatory ...

THE EFFECT OF A DIELECTRIC COVER ON THE CURRENT DISTRIBUTION AND INPUT IMPEDANCE OF PRINTED DIPOLES
(Ieee-inst Electrical Electronics Engineers IncNew York, 1984)
Effect of welding parameters on microstructure of Fe-based nanostructured weld overlay deposited through FCAW-S
(Taylor & Francis, 2016-08)
Lately, modern hardfacing tubular wires for semiautomatic welding with gas protection and without it have been developed. These wires deposit Fe-based nanostructured alloys with high abrasive wear resistance. The information ...
Automatic dimming multi-lamp fluorescent management system with active input power factor corrector stage
(Inst Engineering Technology-iet, 2012-01-01)
This study presents the development and implementation of an automatic multi-lamp lighting fluorescent system, based on electronic ballasts with capacity of ideal programmable preheating and dimming capabilities, and digital ...
