Year by year, the demand for recycling energy is raising up. As a result, the usage of solar panels have been growing up. In this presentation, we will create model of solar photoelectric module with program MATLAB. We have started to program model of solar panels' main aspects and qualities of photovoltaic effects of progress modeling physics of semiconductor. To this purpose, we will make form of whole module by using photovoltaic effects. First, we saw model by the main formula account measurement of photocurrent. Then, we gathered every model assesses (shunt resistance current, saturation current and reverse saturation current) turn by turn. By adding to this panel 200-Watt- panels, given assessed amount of solar lights and temperature, exchanged electric parameters of photoelectric module. We have found maximal measures of current and voltage because of this special algorithm. As a consequences, affecting variety of solar lightening and temperature, we took characteristics of volt-ampere and volt-power, studied their extensive effects of current and voltage. We can see, the normal condition of temperature for the solar panels recognized as 25°C and solar lightening as 1000 W/m². [ABSTRACT FROM AUTHOR]

This article substantiates the criteria for placing a current transformer in the stator wedges and obtaining an output voltage that can be used to control and regulate the reactive power of asynchronous motors. As a result of the passage of current through the stator windings in a sensitive element located in the wedges, an output signal is obtained; this output signal is generated in the form of voltage due to magnetic currents that determine the reactive power of an asynchronous motor. The use of this signal in monitoring and regulating reactive power leads to increased accuracy, saving energy and resources. Research has shown that the output voltage of the current converter is linearly related to the change in the stator current of an asynchronous motor, and the results obtained in practice are adequate to theoretical calculations.

Third harmonic generation of ultra-short femtosecond laser pulse (up to duration of 5 fs) in argon has been analysed numerically. The influences of gas ionization and dispersion effects up to the third order on change of the efficiency conversion of the nonlinear optical process have been investigated. The role of chirped incident pulse and its transform limited form on forming the harmonic has been discussed. Determination of high efficient regimes of the harmonic in the presence of ionization and high order dispersions has been discussed. [ABSTRACT FROM AUTHOR]
