Research
In power electronics we process electric power through semi-conductor switches. These power devices (MOSFET or IGBT) are at the heart of any power electronic converter. In many of our work we try find new topologies (configuration of switches) and modulation strategy (switching scheme), that improve power conversion efficiency and reduce size and cost. We emphasise on design, fabrication and testing of state of the art and advanced power converters. We do work on cutting edge embedded solutions for power electronic applications.

APPLICATIONS
Grid integration of Renewables
In power electronics we process electric power through semi-conductor switches. These power devices (MOSFET or IGBT) are at the heart of any power electronic converter.
Powering Electric Vehicles
Electric Vehicles (EV) pose a wide range of challenging problems to the power electronic engineer. In EV basically we drive an electric motor (Engine) from a battery (Fuel).
Space Power Electronics
Satellites are primarily powered by solar energy and hence require power converters to supply the onboard loads. We are working with ISRO to develop a high frequency power system for the satellites.
