Power Electronics converters : circuit topology, control, and applications


Power electronics converters are vital for many applications such as interfacing systems of renewable resources, electrical drives, electric vehicles, and others. The research on ciruit topologies and control of power electronics converters are motivated by improving the performance and functionality of the existing converters. New topologies of power electronics converters are investigated and analyzed. My research work focus on the operation and control of proposed converters which are verified using computer simulation and experimental setups. Applications includes integration of Photovoltaic systems and wind turbines with the electrical grids or microgrids, current flow controllers used for the multi-terimal DC grids, uninterruptible power supplies, dynamic voltage restorers,  and energy storage systems.
