(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
In this work, a new dc-ac converter is proposed for grid integration purposes, namely, capacitor-tapped multi-module dc-ac voltage source converter. The main advantages of the proposed converter when compared with the ...
A five-phase induction machine model using multiple DQ planes considering the effect of magnetic saturation
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multiphase phase induction machines are usually modeled using multiple dq planes, where complete decoupling between these sequence planes is usually assumed. This assumption may be accepted if the magnetic circuit is assumed ...
Maximum Power Transfer Of Pv-fed Inverter-based Distributed Generation With Improved Voltage Regulation Using Flywheel Energy Storage Systems
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
One of the main issues accompanied with the high penetration of PV distributed generation (DG) systems in low voltage (LV) networks is the overvoltage challenge. The amount of injected power to the grid is directly related ...
Transformer-less Grid-Connected High-Voltage Marx Pulse Generator with Unity Power Factor for Domestic Drinking Water Disinfection
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Qatar has no rivers, thus the main natural water resource in Qatar is the groundwater table. The average groundwater recharge from rainfall is approximately 55.9 million m3/year, in addition to 2.2 million m3/year inflow ...
Symmetrical Nine-Phase Drives with a Single Neutral-Point: Common-Mode Voltage Analysis and Reduction
(
MDPI
, 2022 , Article)
Power converters generate switching common mode voltage (CMV) through the pulse width modulation (PWM). Several problems occur in the drive systems due to the generated CMV. These problems can be dangerous to the insulation ...
A sensorless Kalman filter-based active damping technique for grid-tied VSI with LCL filter
(
Elsevier Ltd
, 2017 , Article)
Employing the LCL passive filter in inverter-based distributed generation to ensure high quality power delivery comes at the expense of poor performance due to the resonance phenomenon. Literature elucidated several active ...
