My research is focused on the optimization of various power electronic converters. I have a strong background in DC-DC converters (such as dual active bridge converter, LLC converter and phase-shifted full-bridge converter) in both EV charging and other grid connected applications and I have carried out analysis on their performance in different scenarios. I also have background in the design, analysis and testing of high-power medium-voltage converters of over 1 MW. I am proficient in various simulation tools including finite element simulation in Ansys. I have developed optimization algorithms for modular grid forming converter considering the number of parallel modules, design of all the main components (such as semiconductor switches, output filters, and cooling system) also considering the load profile and life-cycle costs. I have also worked with novel topologies such as the Five-level nested inverter with neutral point connection, that was also patented by few of the authors. I myself hold two patents related to power electronic converters. I have also been working with grid connected power electronic systems related to LVDC grids that have been designed, built and tested by the authors of the publications in my publication list and operated in a real environment as a part of the electricity grid in combination with a battery energy storage.
