I broadly work in the area of Power Electronics

Over the course of my PhD, I  have worked extensively with voltage source inverters, induction motors, and their control. More specifically, I worked with the inverter dead-time effect (a system non-ideality) and dead-time induced instability issues in Volts-per-Hertz induction motor drives. Such motor drives are commonplace in fans, pumps and compressors used for various industrial applications. The work involved all aspects of research - extensive analysis, simulations and experiments.  Further, me and my advisor Prof G. Narayanan also collaborated with L&T technology services, Bangalore and Integrated Electric, Bangalore, in studying and mitigating instability observed in certain inverter-fed motor drives.

At ABB, I worked with an international R&D team on the control development and fault studies of a new Modular Multilevel Converter topology for high power HVDC power transmission. I also worked briefly on power electronic systems for FACTS and DC Traction applications.

I am interested in research on power electronic converters and their control spanning across motor drives, HVDC and FACTS, electric traction systems, and  renewable integration.

Currently I am working on modular energy storage systems for grid connected applications with Mr Aby Joseph, CDAC Thiruvananthapuram. I am also  collaborating with Dr Vijay, IIT Palakkad on switched reluctance motors, and on power conversion systems of a low altitude glider. I also work with PV inverter fed motor drives.
