Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

This paper presents a performance analysis of control methods to track the maximum power point (MPP) of photovoltaic (PV) systems for water pumping stations in DJORF TORBA, BECHAR. The tracking takes place under different meteorological conditions. The investigated PV system consists of a solar panel, a DC/DC converter and a buck-boost converter connected to a load. The compared MPPT (Maximum Power Point Tracking) algorithms are the Perturb and Observe (P&O) method, the cascaded PI control, a Mamdani fuzzy logic technique and finally a sliding mode control. The parameters taken into account for the performance evaluation of the MPPT algorithm are the efficiency, the uniform and dynamic behavior of the system under changing conditions such as temperature and irradiation and thus the signal ripple. After comparing these methods and presenting the one with the best results using MATLAB Simulink software for further analysis with different irradiation and temperature conditions. The simulation results are presented and they demonstrate the effectiveness of the sliding mode control method in parameter variation scenarios. The simulation was performed with real data parameters courtesy of the Algerian National Company of Electricity Production (Sonelgaz).
There have been different methods to alleviate the fluctuations in voltage stability or its effects in appliances, one of such ways is the use of stabilizers. This paper expounds the study in the form of comparatively analyzing the two most commonly types of stabilizers in use, the transformer-based which is more common and the transformer-less stabilizers. Herein, the design methodology of the transformer-based and transformer-less stabilizers are shown and the waveforms of the performance stages of the two types of stabilizers are analyzed together with the output for the two cases. Finally, a tabular representation of the results of the comparative analysis is drawn.
