“…The three-phase inverter consists of three switching arms, each one is composed of two cells with a diode and a transistor in antiparallel with DC voltage as input and three AC voltage as output [28]. The inverter is modeled by associating to each arm a logic function F that determines its conduction states: where i=1, 2, 3.…”

This paper investigates the performances analysis of PV-RO desalination system under uniform and non-uniform irradiance conditions. The main objective is the application of Extremum Seeking Control (ESC) to the GPV side in order to overcome the generated power and water quantity losses to improve the performance of the whole system. The technical design of the developed system is based on an existing RO desalination unit beside that real climatic data taken from a local mast are involved in this study. The modeling of the whole system and the control techniques adopted in this study are fully formulated. The whole system is modeled and controlled using MATLAB/Simulink. Different scenarios (healthy and shaded) based on real climatic data have been used to carry out the results. The ESC used shows its effectiveness to extract maximum power under shaded conditions for all the proposed scenarios. Compared with conventional controllers, this technique can offer extra power surrounding 685W in several cases. Furthermore, the shading conditions can affect widely freshwater production whose losses are estimated at around 82.91% for critical scenarios. The findings results are very significant for industrialists working in this field.

“…The basics PWM topologies including single PWM produced by comparing rectangular reference wave with triangular carrier wave, the multiple PWM and the Sinusoidal PWM (SPWM)using sinusoidal reference wave and triangular carrier wave [10]. There are several advanced PWM topologies depending on the carrier used such as Alternative Phase Opposite Disposition PWM (APOD-PWM), Harmonic-Injection PWM (HI-PWM), Carrier Based Space Vector PWM (CB-SVPWM) and stepped modulation [10,11]. Although PWM is still widely used in industrial applications [12,13], it still has some limitations.…”

Broken rotor bar (BRB) is one of the most common fault types of induction motors. One of the common methods to detect the broken rotor bars is the observation of the characteristic sideband frequencies in the stator current. If the motor is lightly loaded, the sideband harmonics are attached to the fundamental frequency of the main supply and the amplitudes of these harmonics are quite low. Therefore, it is difficult to detect the broken rotor bars under light loading conditions by using conventional motor current signature analysis (MCSA) methods. Moreover, in some cases, the sideband harmonics of fundamental frequency may exist although there is no rotor fault in induction motors due to load oscillations. Therefore, there is a risk for false broken rotor bars alarm with the existence of lower amplitude of harmonics. This paper provides an alternative approach for the detection of broken rotor bars by applying Hilbert envelope analysis along with Shannon entropy to stator current signals. The proposed method includes two-stage evaluation system to eliminate false BRB alarms such as detecting sidebands from envelope spectrum and calculating entropy rates from envelope signals. The results are verified experimentally under 25 %, 50 %, 75 % and 100 % loading conditions.
