An LCL filter-based grid-interfaced three-phase voltage source inverter: Performance evaluation and stability anaylsis
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Power converters in grid connection applications commonly employ Sinusoidal Pulse-Width Modulation (SPWM) technique. Passive filters are employed in order to attenuate the generated switching current ripples and reduces ...
A Modular Multilevel Converter with Ripple-Power Decoupling Channels for Three-Phase MV Adjustable-Speed Drives
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
This paper presents a drive system based on a modular multilevel converter (MMC) with high-frequency magnetic channels between adjacent-arm submodules (SMs), suitable for medium-voltage, high-power three-phase variable-speed ...
Robust Hybrid EKF approach for state estimation in multi-scale nonlinear singularly perturbed systems
(
IEEE
, 2014 , Conference Paper)
In this paper a general framework is developed for state estimation in a class of nonlinear continuous-time singularly perturbed systems. Our approach is based on the hybrid extended Kalman filter in which observations are ...
A Collaboration Incentive Exploiting the Primary-Secondary Systems' Cross Interference for PHY Security Enhancement
(
IEEE
, 2016 , Article)
We investigate the spectrum sharing possibility as an incentive to enhance the physical layer security. The concept behind is that a legitimate source-destination pair, communicating in the presence of a passive eavesdropper, ...
Optimized micro-climate controller of a greenhouse powered by photovoltaic generator
(
IEEE
, 2014 , Conference Paper)
Energy resources and food security are the most important issues for many countries around the world. Climatic conditions affect the agriculture production which is the backbone of the food security for all countries. ...
Phase noise mitigation in OFDMA uplink
(
IEEE
, 2014 , Conference Paper)
This paper addresses the problem of the phase noise induced spectral spread in an OFDMA uplink scenario. Accompanied with power differences between the users at the receiver in a multiuser case, the phase noise induced ...
A component map tuning method for performance prediction and diagnostics of gas turbine compressors
(
Elsevier Ltd
, 2014 , Article)
In this paper, a novel compressor map tuning method is developed with the primary objective of improving the accuracy and fidelity of gas turbine engine models for performance prediction and diagnostics. A new compressor ...
Parameter identification of five-phase induction machines with single layer windings
(
IEEE
, 2014 , Article)
Despite the increased interest in multiphase induction machines for safety-critical applications, machine parameter identification for the different sequence planes is still a challenging research point. In most available ...
Opportunistic spectrum sharing in relay-assisted cognitive systems with imperfect CSI
(
IEEE
, 2014 , Article)
In this paper, we consider spectrum sharing between cognitive radio (CR) users and a licensed primary user (PU) to enhance the spectrum efficiency. In the considered scenario, the PU is not able to successfully transmit ...
ANN-based system for a discrimination between unbalanced supply voltage and phase loss in induction motors
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
It is documented that almost 98% of all voltage generated by electric utilities has up to 3% unbalance. Single phasing fault deserves special attention since phase loss is considered the worst case of unbalanced supply ...
