Abstract: Solar energy is becoming one of the most expanding renewable energy it is getting more prominence. Sun trackers can substantially improve the electricity production of a photovoltaic (PV) system. This paper proposes a novel design of a dual-axis solar tracking PV system that utilizes the feedback control theory along with a four-quadrant light-depe... Show More

Abstract: In this paper, a dual-conversion online static UPS and Line-Interactive UPS system were modeled and simulated using PSIM software. The components of the proposed design were specified based on pre-defined constrains, and the dynamic behavior of the system was modeled through state-space equations. With the system components characterized, a suitabl... Show More
