My research interest is primarily on power quality. Topologies and Control of power converters for Custom Power Devices, FACTS, Renewable Power, Electric Vehicles etc are present interests. The multi functional control of Solar PV based grid connected systems and the MPPT (Maximum Power point Tracking) control of solar PV Inverters demands more attention. Moreover, wind and fuel cell based power generation systems are also fascinating. Some of our journal publications are;
