Evaluation of a multilevel cascaded-type dynamic voltage restorer employing discontinuous space vector modulation
(
IEEE Industrial Electronics Society
, 2010 , Article)
In this paper, the application of a cascaded multilevel inverter as a dynamic voltage restorer (DVR) is investigated. Two discontinuous multilevel space vector modulation (SVM) techniques are implemented for DVR control ...
Channel modelling and performance analysis of V2I communication systems in blind bend scattering environments
(
EMW Publishing
, 2014 , Article)
In this paper, we derive a new geometrical blind bend scattering model for vehicle-to- infrastructure (V2I) communications. The proposed model takes into account single-bounce and double- bounce scattering stemming from ...
Pulse width modulation technique for a three-to-five phase matrix converter with reduced commutations
(
Institution of Engineering and Technology
, 2016 , Article)
Variable-speed multiphase drive systems have become an increasingly important topics compared with conventional three-phase one due to their distinct advantages. This study presents a new pulse width modulation (PWM) ...
A Pulsewidth Modulation Technique for High-Voltage Gain Operation of Three-Phase Z-Source Inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Z-source inverter (ZSI) was recently proposed as a single-stage buck-boost dc-ac power conversion topology. It augments voltage boost capability to the typical voltage buck operation of the conventional voltage source ...
HVDC shunt tap based on three single-phase half-bridge series-connected MMCs operated under 2L modulation
(
Institution of Engineering and Technology
, 2019 , Article)
In this study, a cost-effective HVDC shunt tap with low-number of relatively low-voltage semiconductor devices and small-sized passive components is proposed. The proposed architecture is based on employing three single-phase ...
Capacitor voltage balancing using redundant states of space vector modulation for five-level diode clamped inverters
(
IEEE
, 2010 , Article)
A redundancy balancing technique for the five-level diode-clamped inverter is presented, which balances the four dc-link capacitor voltages at high modulation index and high power factor. The technique is based on dividing ...
Studying the effect of over-modulation on the output voltage of three-phase single-stage grid-connected boost inverter
(
Elsevier B.V.
, 2013 , Article)
Voltage boosting is very essential issue in renewable-energy fed applications. The classical two-stage power conversion process is typically used to interface the renewable energy sources to the grid. For better efficiency, ...
DC-link capacitor voltage balancing for a five-level diode-clamped active power filter using redundant vectors
(2013 , Article)
This paper investigates the compensation and modulation processes of the five- level diode-clamped active power filter, compensating a three-phase rectified resistor-inductor load with redundant vectors. From the analysis, ...
Precoding-Aided Spatial Modulation for the Wiretap Channel with Relay Selection and Cooperative Jamming
(
Hindawi Limited
, 2018 , Article)
We propose in this paper a physical-layer security (PLS) scheme for dual-hop cooperative networks in an effort to enhance the communications secrecy. The underlying model comprises a transmitting node (Alice), a legitimate ...
