This paper presents unified power quality conditioner (UPQC) system based on three-level neutral point clamped (NPC) using Fuzzy and ANN controllers. The proposed UPQC is able to mitigate source current harmonics and compensate all voltage…

This paper proposes a simple control scheme for UPQC (Unified Power Quality Conditioner) system based on five-level NPC (Neutral Point Clamped) inverter capable to compensate all disturbances under all voltage conditions. The proposed UPQC is…

This paper presents the performance of shunt active power filters (Shunt APFs) which can compensate harmonic currents generated by no-linear load based on five and seven-level neural point clamped (NPC) inverters. Multilevel inverters are currently…

The dynamic performances of a permanent magnet synchronous motor (PMSM) and an asynchronous motor (ASM) connected to a photovoltaic (PV) array through an inverter are analyzed. The mathematical models of PV array, inverter/motor and controller are…

This study focus on the optimization of operating conditions for activated carbons preparation starting from synthetic waste (tires) and agricultural waste (date pits) by chemical activation. The experimental design was used in order to determinate…

يهدف هذا البحث إلى بيان الارتباط الوثيق بين الأحكام الجزئية الواردة في السنة النبوية وما يتعلق بها من الأصول العامة والمقاصد الكلية للشريعة الإسلامية، وذلك من خلال بيان منهج الرسول j ومن سار على نهجه من الصحابة الكرام في ربط المسائل الجزئية بأصولها…

The controversy in American public education over the issue of teaching evolution-creationism is one of the nation’s most serious undertakings. While Protestant fundamentalists exhibited strong opposition against all aspects of modernism, Darwin’s…
