With the advancement of the power semiconductor in the forms of Si IGBT, there was an increasing drive to use power converters for the pulsed power supply at high voltage high power due to its relatively lower conduction losses. However, their performances still need to be improved in terms of power density, efficiency, and faster transient responses. And these can be achieved using the wide bandgap (WBG) devices like Silicon Carbide (SiC) and Gallium Nitride (GaN). One of my primary research interests is to develop pulsed power converter with the WBG devices for various applications in medical and other industrial processes. Further, I want to continue my research on WBG based power converters for grid integration of renewable resources. Broadly I am also interested in working on power converters with applications in electric transportation including traction drives, DC-DC converters, fast chargers, and green hydrogen.
