Application of The calculated PWM technique in the photovoltaic pumping system

This paper aims to reach at an improved control and optimization between the different functions of the elements of a solar pumping system. The solar panel can supply maximum power only for defined output voltage. The operation to get the maximum power depends on the terminals of load, mostly a non-linear load like induction motor. That is why we have given in this work two different solutions for two problems. Firstly, we used an intelligent control method for the tracking module inserted in the photovoltaic system under variable temperature and irradiance conditions. The tracking module can be used to maintain the operation of the photovoltaic panel at maximum power by controlling the voltage or current generator independently of the load. Secondly, ours pumping system was tested with the calculated pulse wide modulation technique inverter to order to reduce the noise, oscillations of the torque and current, also the disturbance on speed.
