A single-stage three-phase DC/AC inverter based on Cuk converter for PV application
Darwish, A.; Elserougi, A.; Abdel-Khalik, A. S.; Ahmed, S.; Massoud, Ahmed; Holliday, D.; Williams, B. W.... more authors ... less authors ( IEEE , 2013 , Conference Paper)This paper presents a new three-phase dc-ac inverter based on the basic Cuk converter. The main feature of the proposed topology is the fact that the energy storage elements as inductors and capacitors values can be reduced ... -
A single-stage three-phase inverter based on cuk converters for PV applications
Darwish, A.; Holliday, D.; Ahmed, S.; Massoud, Ahmed; Williams, B. W. ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)This paper presents a new three-phase inverter based on the Cuk converter. The main feature of the proposed topology is that the energy storage elements, such as inductors and capacitors, can be reduced in order to improve ... -
Fault current contribution scenarios for grid-connected voltage source inverter-based distributed generation with an LCL filter
Darwish, A.; Abdel-Khalik, A. S.; Elserougi, A.; Ahmed, S.; Massoud, Ahmed ( Elsevier , 2013 , Article)Inverter-based distributed generation (IBDG) is characterized by its negligible fault current contribution compared with synchronous generators due to its inherent non-overload capabilities. Thus, IBDG hardly affects the ... -
The One Dimensional Inverse Spectral Problem Of A Generalized Stationary Schrodinger Equation
Megahed, F. A. [ف . ا. مجاهد]; Darwish, A. A. ( Qatar University , 1996 , Article)In this paper we study the inverse problem on the half line for a generalized stationary one dimensional Schrodinger equation. We consider the solutions of the differential equation and study its properties. Given the ... -
Simplified generic on-line PWM technique for single phase grid connected current source inverters
Abdelsalam, A. K.; Massoud, Ahmed; Darwish, A.; Ahmed, S. ( Institute of Electrical and Electronics Engineers Inc. , 2012 , Conference Paper)Mandatory restrictions for a current source inverter's (CSI's) proper operation, like continuity of the DC link current, complicate the corresponding PWM generation especially in the case of single phase systems. Classical ... -
Single phase grid connected current source inverter: Mitigation of oscillating power effect on the grid current
Darwish, A.; Abdelsalam, A.K.; Massoud, Ahmed; Ahmed, S. ( Institution of Engineering and Technology , 2011 , Conference Paper)Although voltage source inverters (VSIs) are the most common DC-AC grid-tied converters, current source inverters (CSIs) are considered to be promising candidate, thanks to their low THD voltages/currents and inherent ...
