Single stage solar pv fed brushless dc motor

In today’s world renewable source of energy plays a vital role for producing electricity. Compared to other renewable sources solar is the most developing ways to producing electricity. It does not have any pollution. A single stage solar PV fed brushless DC motor is used for agricultural purpose which can be used in the water pump. It is the standalone system which can be installed in the agricultural field. A single stage solar PV fed energy conversion system eliminates conventional DC-DC converter which increases size, complexity and reduced efficiency. It is done by a simple voltage source converter which feeds BLDC motor-pump. DC link circuits are used primarily to balance the instantaneous power variations between the input source and the output load. The bulky capacitor at the dc link is replaced with a low valued capacitor using pulse width modulation switching of VSI. The capacitor is connected across PV array serves to provide constant voltage to converter circuit. The capacitor carries ripple current. A diode in series with the PV array prevents the flow of reverse current. The speed of the motor can also be adjusted accordingly.
