Modified transformerless dual buck inverter with improved lifetime for PV applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The Dual Buck Inverter (DBI) possesses no shoot-through concerns and it can improve the efficiency by utilizing power MOSFETs. This is because at accidentally triggered shoot-through states; two inductors are in-parallel ...
Dual Active Full Bridge Implementation on Typhoon HIL for G2V and V2G Applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The Dual Active Full Bridge (DAFB) is one of the promising isolated DC/DC converter topologies that will play a significant role in the future integration of Electric Vehicle (EV) into Smart Grids (SGs). This is due to its ...
Novel shunt-less filters for grid-connected transformerless photovoltaic applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The existing ground leakage current suppression methodologies are effective when Photovoltaic (PV) arrays' stray capacitors are small (in several nano-Farads). In such case, the High Frequency (HF) content of the inverter's ...
Novel LCL filter for non-isolated photovoltaic inverters with CM current trapping capability for weak grids
(
IEEE
, 2018 , Conference Paper)
© 2018 IEEE. In this work, a novel LCL filter topology for non-isolated Photovoltaic (PV) applications is developed. This topology has the ability to trap the High-Frequency (HF) Common Mode (CM) current inside the PV ...
Electrolytic capacitor-less dual buck inverter with CM and DM active resonance damping control for Non-isolated grid-connected PV applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The shoot-through problem of conventional H-Bridge inverters imposes a threat to system's reliability and efficiency. This is because the unintentional shoot-through state short-circuits the DC-Link capacitor. To overcome ...

(
Springer New York LLC
, 2019 , Article)
The present research work focuses on the synthesis, characterization and properties of novel polyelectrolyte multilayered microcapsules used as smart additives in organic coatings for corrosion protection of steel parts. ...
Self-healing performance of multifunctional polymeric smart coatings
(
MDPI AG
, 2019 , Article)
Multifunctional nanocomposite coatings were synthesized by reinforcing a polymeric matrix with halloysite nanotubes (HNTs) loaded with corrosion inhibitor (NaNO3) and urea formaldehyde microcapsules (UFMCs) encapsulated ...
Switchless power decoupling and switchless leakage current elimination in grid-tied inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
This paper presents a grid-tied single-phase transformerless inverter that eliminates simultaneously the leakage current issue and the double grid frequency power pulsation without additional active circuitry. The control ...
Semi-transparent thermo-electric cells based on bismuth telluride and its composites with CNTs and graphene
(
National Institute of Optoelectronics
, 2019 , Article)
In this paper, semi-transparent thin film thermo-electric cells based on the composite of bismuth telluride (Bi2Te3, p-type and n-type) with graphene and carbon nanotubes (CNTs) have been reported. The voltage, current and ...
Development of innovative indoor/outdoor air quality monitoring for environmental impact assessment in the State of Qatar
(
WITPress
, 2014 , Article)
Air pollution is one of the most crucial factors affecting the quality of life and health of increasingly urban populations; a country with a fast-growing economy based on hydrocarbons such as Qatar is no exception. In ...
