	abstract = {This investigation examines mathematical modelling and experimental validation of two types of solar cookers: a box type with tilted intercept area equipped with one external reflector, and a parabolic cooker with a new configuration. Experiments were carried out with the cookers filled with two kilograms of water from 08:00 to 15:00 solar time. During the experiments, temperature gain in the box-type solar cooker was recorded at about 69.8 {\textdegree}C and in the parabolic-type solar cooker at 73.6 {\textdegree}C at the stagnation point. Direct normal irradiation in three distinct study areas was observed and found that it varied from 7.6 to 10 kWh m-2. Cooking pot placed in parabolic cooker was varied between 130 and 132 {\textdegree}C. Centre and south-east regions of study areas where global irradiation varied from 8 to 8.4 kWh m-2 were found suitable for box-type solar cooker and cooking pot temperature were found in the range of 100 {\textdegree}C to 105 {\textdegree}C. Mathematical modelling was programmed in MATLAB. The theoretical results were consistent with experiential data for both types of solar cookers. The effectiveness of the two cooker types can be deduced from the maps. It is found the use of the cookers in Northern and Southern regions of the country was not identical. Their suitability for cooking depends on the amount of solar radiations received.},

	abstract = {Knowledge of solar residential device{\textquoteright}s thermal performance is necessary in order to optimize their output. This requires a database of solar radiation for locations for which the system is being installed. In this regard, temperature maps are generated for a realized parabolic solar cooker using an improved solar radiation model for 48 cities in Algeria. The maps are drawn for two cases: clear and cloud skies in winter and summer seasons, which allow comparison between cooker performances. The developed approach consists in converting obtained results from optical simulation to thermal values based on Stefan-Boltzmann law. Experimental data for receiver temperatures and solar radiation measured at Gharda{\^\i}a city in January month were used for the validation. It was found that cooker temperature values obtained from the measurements and that estimated using the proposed approach were in good agreement. The mapping results indicate that the realized cooker is efficient in all the country throughout the summer season with temperatures exceeding 110 {\textdegree}C. The use of the cooker will be reduced by going in South to North regions during the winter months, depending on the amount of solar radiations received. Nevertheless, the major area of the country is favorable for the use of the cooker during this period of the year even when the sky remains cloud.},

	To reach the increasing demand for power quality and power rating along with lower harmonic distortion and lesser electromagnetic interference, the multilevel inverter is needed. Solar energy is one of the favorable renewable energy resources, and the multilevel inverter has been proven to be one of the important enabling technologies in photovoltaic utilization. This paper is based on the study of behavior of a nine levels NPC three-phase inverter topology interfacing multistring photovoltaic system to the electric grid. This inverter is controlled by the pulse-width modulated strategy. Eight carrier waves of the same frequency and different amplitudes are compared with two references (a sine wave and its opposite) for generating the control signals of the switches. Some DC/DC boost converters are used to amplify the voltage produced by the photovoltaic generators. Each of these converters is controlled by a fuzzy Logic-based maximum power point tracking algorithm (FLBMPPTA) in order to track the maximum power point of the GPV; results of simulation in Matlab environment are given and discussed.

The solar cooker was designed with an inclined aperture area, realized and experimentally tested at Applied Research Unit on Renewable Energies of Gharda{\"\i}a (32.39 {\textdegree}N, 3.78 {\textdegree}E, 463 m), Algeria. The developed cooker is equipped with one reflector mirror on its lid. The experiments have been carried out with the cooker empty, filled with one or two liters of water from 08:00 to 15:00 solar time, the thermal profiles of various components of the cooker were assessed at Gharda{\"\i}a site Sahara climatic conditions on clear days in both winter and summer months. According to the values of two figures of merits suggested by International Standards and evaluated by the experimental studies, the configuration with an inclined aperture area of the cooker resulted in good cooking performances, especially in winter when the sun{\textquoteright}s elevation is low; keeping the realized cooker performances in range of the international standard tests. The results of this study indicate also that the average daily energy and exergy efficiency of the realized cooker was 16.2 \% and 0.90 \% respectively, during the experimental period, which indicate a significant difference between the results of energy and exergy analyses. Thus developing such a box solar cooker can improve the efficiency of the design and use a position of the system to prepare food in a shorter time.},
