Implementation of Power Quality Enhancement using Hybrid Series Active Filter

The quality of the power supply is an important concern over the years. The quality of the power can be considered with the factors like current, voltage, and power factor etc. The parameters like the stability and reliability of the power plays an important role in deciding the quality of supply. The end user always faces the economic losses if the quality of the supply is inadequate. The main cause of degradation in power supply is the harmonics. The voltage and current harmonics are the issues to be addresses to enrich the power quality. The active filters are helpful to improve the quality of power by means of mitigating the harmonics. Authors have implemented the hybrid active power filter to improve the quality of the power supply. The sliding mode of the controller is implemented to assure the better performance of the system.
