| Abstract | ||||
| In this paper the electrical performance of a DC series motor supplied by a photovoltaic power supply (PVPS) through a pc chopper is evaluated. A PVPS is operated at a maximum power point. this means that it consists of photovoltaic array and a maximum power traking system . The later is used to trak maximum power point. A DC chopper is used for controlling thr motor current and the motor torque the effect of insolation level on the motor current suppliing at different speed and at various firing anglesof thyristor is presented. The effect of series connections of solar cells on the motor performance is also studied. The effect of DC chopper-which is consider as a control unit- upon the motor performance is illustrated. The relationship between the motor current and intensity of radiation at different speed is studied. The study shows that: the motor current increases with increasing of the illumination and the main thyristor ON time. Besides, the motor current is inversely proportional to the motor speed. The effect of series combination is also illustrated. The study shows that a linear variation of motor current wiyh the number of series cells. | ||||
