This paper deals with a DFIG model employing nine switches AC/AC converter. As compared to the conventional DFIG employing Back to Back power converter the nine switch converter requires fewer switches and gate drive circuits. Therefore proposed topology results in reduction of installation area and cost. The nine switch converter DFIG is applied to the wind turbine and integrated with the grid. The results reveal that even though change in wind speed occurred, the generator terminal voltage and frequency remain same. The generator output power follows the wind speed and delivers the more power to the grid.
