Modern industries are installed with an adjustable speed drive (ASD), which is more sensitive to power quality issues. The most common reason for the tripping of ASD is the voltage sag. Hence, the impact of various types of sags on the performance of ASD is presented in this paper. The basic topology of ASD fed by uncontrolled rectifier is presented in this paper. Different types of voltage sags occurred at point of common coupling with their causes are also discussed. To study the impact of
