The ZVS-PWM commutation cell applied to the DC-AC converter
(1997-12-01)
This paper presents the analysis of a dc-ac converter using a zero-voltage-switching (ZVS) commutation cell. First, we show the cell applied to the buck converter. The stages of operation are presented along with the main ...
An LMI Approach to Full- and Reduced-Order Switched Luenberger Observers for Switched Affine Systems
(2016-12-01)
This work deals with reduced-order Luenberger-like observer design and control for switched affine systems. Formulation of state-dependent and dynamic output-dependent switching laws for those systems was already addressed, ...
A new family of zero-current-switching PWM converters and a novel HPF-ZCS-PWM boost rectifier
(Institute of Electrical and Electronics Engineers (IEEE), 1999-01-01)
A new family of direct current (DC) to DC converters based on a zero current switching pulse width modulated (ZCS-PWM) soft commutation cell is presented. This ZCS-PWM cell is consists of two transistors, two diodes, two ...
Robust switched control design for electrically stimulated lower limbs: A linear model analysis in healthy and spinal cord injured subjects
(2020-09-01)
Functional electrical stimulation (FES) has been used to restore and aid motor functions in paraplegics, promoting better therapeutic results for its users. From experimental results, one can observe that there exists an ...
An iterated sample construction with path relinking method: Application to switch allocation in electrical distribution networks
(2013-01-01)
We present a metaheuristic approach which combines constructive heuristics and local searches based on sampling with path relinking. Its effectiveness is demonstrated by an application to the problem of allocating switches ...
Optimal Restoration/Maintenance Switching Sequence of Unbalanced Three-Phase Distribution Systems
(Ieee-inst Electrical Electronics Engineers Inc, 2018-11-01)
This paper presents a mixed-integer non-linear programming (MINLP) model for the optimal restoration/maintenance switching sequence of unbalanced three-phase electrical distribution systems. Once the protection coordination ...
Robust Control of Switched Linear Systems with Output Switching Strategy
(2015-10-29)
This paper investigates the robust control problem of continuous-time uncertain switched linear systems, using only a switching strategy depending on the plant output. The proposed method is based on linear matrix inequalities ...
Boundary Control of Full-Bridge ZVS: Natural Switching Surface for Transient and Steady-State Operation
(Institute of Electrical and Electronics Engineers, 2014-02)
This paper presents the use of a high-performance boundary controller for the full-bridge zero-voltage-switching topology. An enhanced dynamic response is obtained by employing the natural switching surface (SS), which is ...
Rise Time and Gain Fluctuations of an Electrooptical Amplified Switch Based on Multipulse Injection in Semiconductor Optical Amplifiers

Reconfiguracao de sistemas de distribuicao radiais utilizando o criterio de queda de tensao
(2000-09-01)
Network reconfiguration in distribution systems can be carried out by changing the status of sectionalizing switches and it is usually done for loss minimization and load balancing. In this paper it is presented an heuristic ...
