A static three-phase to five-phase transformer based on Scott connection
(
Elsevier B.V.
, 2014 , Article)
Multiphase machines have become challenging candidates for safety-critical applications that require wide fault tolerant capabilities and higher system reliability. However, this adds more complexity to the adopted power ...
Analysis of local time-frequency entropy features for nonstationary signal components time supports detection
(
Elsevier Inc.
, 2014 , Article)
Identification of different specific signal components, produced by one or more sources, is a problem encountered in many signal processing applications. This can be done by applying the local time-frequency-based Rényi ...
Investigations of multi-carrier pulse width modulation schemes for diode free neutral point clamped multilevel inverters
(
Korean Institute of Power Electronics
, 2019 , Article)
Multilevel Inverters (MLIs) are widely used in medium voltage applications due to their various advantages. In addition, there are numerous types of MLIs for such applications. However, the diode-less 3-level (3L) T-type ...
Hybrid-boost modular multilevel converter-based medium-voltage multiphase induction motor drive for subsea applications
(
Korean Institute of Power Electronics
, 2019 , Article)
This paper proposes a hybrid-boost Modular Multilevel Converter (MMC) for the Medium-Voltage (MV) Variable Speed Drives (VSDs) employed in subsea applications, such as oil and gas recovery. In the presented architecture, ...
Measuring time-varying information flow in scalp EEG signals: Orthogonalized partial directed coherence
(
IEEE
, 2014 , Article)
This study aimed to develop a time-frequency method for measuring directional interactions over time and frequency from scalp-recorded electroencephalographic (EEG) signals in a way that is less affected by volume conduction ...
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 ...
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, ...
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 ...
