Control strategies for unified power quality conditioner to mitigate voltage sag due to large motor starting during fault

As induction motors are the heart of industrial industries for electromechanical conversion, voltage sags during large motor starting have become the most frequent Power Quality (PQ) problem. Induction motors are one of the most prominent sources of voltage sag problem. These disturbances can cause...
