Three phase Induction Motors (IM) are normally used in industries. The continuous process operations of the industries are controlled by Adjustable Speed Drive (ASD) fed IM. The power quality (PQ) problems which occur in the power system are mainly voltage sag and swell. They affect the performance of IM. This is due to the decrease in DC-link voltage of an ASD. It leads to the reliability problem and heavy financial losses happen to the industries. To maintain the constant
DC-link voltage of an ASD, ride-through alternate has to be provided.
In this paper, Cuk converter is provided as a ride-through alternate to mitigate both voltage sag and swell conditions. The MATLAB simulation and hardware validation have been done for 1.5 kW,
400 V, 50Hz three phase induction motor drive under type A voltage sag with 50% sag depth and instantaneous swell conditions.
