Current research areas:
Power Converters for Power System Applications
The work focuses on developing advanced converter topologies, and their modulation and control methods for medium to high-power applications. Recent development focuses on Modular Multilevel Cascaded Converters, Matrix Converters.
Flexible AC Transmission Systems Devices (FACTS) for Smart Grid
Noval control methods for FACTS devices such as STATCOM, UPFC and IPFC. Developing advanced PLL and filtering techniques. Recent work has led to the development of new optimal control and phase locking algorithms for UPFCs. A prototype active power filter using a four-limb flying capacitor multilevel converter.
Control of Islanded Micro Grid
Developing control schemes for STATCOM with energy storage components for both active and reactive power compensation in ialanded micro grid.
Module-Integrated Photovoltaic and Converter Units
Module–integrated PV and converter (MIPC) units have emerged as a promising technique for achieving maximum power generation for mismatched or partially shaded PV modules. The research investigates MIPC with different converter topologies and configurations and their control methods.
