Common-mode voltage and vibration mitigation of a five-phase three-level NPC inverter-fed induction motor drive system
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Common-mode (CM) voltage is one of the main reasons for the flow of bearing currents in induction motors (IM) that ultimately leads to the bearing failure and causes severe vibrations. For three-phase IM drives, many works ...
Micro-Doppler characteristics of elderly gait patterns with walking AIDS
(
SPIE
, 2015 , Conference Paper)
In this paper, we analyze the micro-Doppler signatures of elderly gait patterns in the presence of walking AIDS using radars. The signatures are based on real data experiments conducted in a laboratory environment using ...
Space vector pulse width modulation techniques for a five-phase impedeance source and quazi impedeance source inverters
(
IEEE
, 2015 , Conference Paper)
Impedance source inverter (ZSI) and its variant quasi impedance source inverter (qZSI) are single stage inverters that transform dc to ac and boost the source voltage at the same time. These topologies have attracted great ...
Performance of Mixed RF/FSO with Variable Gain over Generalized Atmospheric Turbulence Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we consider a free-space optical (FSO) communication scheme with the help of a variable gain relay where the links from the source to the relay are radio-frequency (RF) links while the links between the relay ...
Effective area spectral efficiency for wireless communication networks with interference management
(
Springer International Publishing
, 2015 , Article)
In this paper, we introduce a new metric, namely, effective area spectral efficiency (EASE), to quantify the spectral efficiency as well as the spatial properties of point-to-point transmission systems and decode and forward ...
Energy-efficient cooperative relaying protocol for full-duplex cognitive radio users and delay-aware primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper considers a network in which a primary user (PU) may cooperate with a cognitive radio (CR) user for transmission of its data packets. The PU is assumed to be a buffered terminal operating in a time-slotted ...
Microcontroller-based inverter topology integrated in PV systems
(
Emerald Group Publishing Ltd.
, 2015 , Article)
Purpose - The purpose of this paper is to study the problem of the leakage currents in transformerless inverter topologies. It proposes a novel topology and how important the adopted control strategy on the power quality ...
A nine-arm modular multilevel converter (9A-MMC) for six-phase medium voltage motor drives
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Dual three-phase (asymmetrical six-phase) induction motors have received significant attention in high power medium voltage drive applications. Typically, two three-phase voltage source converters are needed to feed such ...
Performance Analysis of Amplify-and-Forward Hybrid Satellite-Terrestrial Networks with Cochannel Interference
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we consider an amplify-and-forward hybrid satellite-terrestrial co-operative network in the presence of cochannel interference (CCI). More specifically, we assume that both the satellite-destination and the ...
Flywheel Energy Storage Systems
(
John Wiley & Sons, Ltd
, 2015 , Book chapter)
Flywheels are one of the oldest and most popular energy storage media owing to the simplicity of storing kinetic energy in a rotating mass. Flywheel energy storage systems (FESSs) can be used in different applications, for ...
