Significant association of close homologue of L1 gene polymorphism rs2272522 with schizophrenia in Qatar
(
Wiley Online Library
, 2012 , Article)
Introduction: Previous reports have found that polymorphisms in the close homologue of L1 (CHL1) gene located on chromosome 3p26 are associated with schizophrenia among different ethnic populations. The aim of this study ...
Sensorless sliding mode observer for a five-phase permanent magnet synchronous motor drive
(
Elsevier
, 2015 , Article)
This paper deals with the sensorless vector controlled five-phase permanent magnet synchronous motor (PMSM) drive based on a sliding mode observer (SMO). The observer is designed considering the back electromotive force ...
Modelling and analysis of a three-phase to five-phase transformer
(
Walter de Gruyter GmbH
, 2014 , Article)
Multi-phase systems are the focus of research in recent times due to their inherent advantages compared to the three-phase counterpart. A lot of research effort has been put to develop commercially feasible multi-phase ...
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 ...
Post fault operation of a dual matrix converter fed open-end load
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the fault tolerant control strategies for a three to five-phase dual matrix converter fed open-end load system. There are two three to five phase matrix converter at both the ends of the load. In ...
Modelling and implementation of SVPWM technique for a fifteen-phase voltage source inverter for sinusoidal output waveform
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper space vector model of a fifteen-phase voltage source inverter (VSI) is presented. The space vector Pulse Width Modulation (SVPWM) of a fifteen-phase voltage source inverter (VSI) with the aim of producing ...
High performance backstepping control of a fivephase induction motor drive
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multiphase electric drives have been investigated and proposed for applications where the highest overall system reliability and the reduction in the total power per phase are required. This paper deals with the high ...
Finite set model predictive current control with reduced and constant common mode voltage for a five-phase voltage source inverter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multiphase drives are now becoming serious competitor to traditional three-phase drives due to reasons of better fault tolerant property and reduced per-phase converter rating that are especially suited to high power drives ...
Common-mode voltage control through vector selection in three-to-five phase matrix converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multi-phase matrix converters (more than three phase) are distinctively advantageous as because of reduced per-phase current and unity power factor operation. The electrical motors supplied through these converters do have ...
Space vector pulse width modulation scheme for three to seven phase direct matrix converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper a generalized multi-phase space vector theory is considered for developing the space vector modulation of a three-phase to seven-phase direct matrix converter (DMC). The modulation is based on the control of ...
