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.
More information about me and my work can be found in my CV link provided above in this page.
I aspire to bring in aspects of practical utility, design and implementation to supplement theory in the courses which I would be offering.
I currently teach / have taught the following courses
1) Power Converter Analysis and Design
2) Power Converters Modulation Control and Applications
3) Power Electronics Simulation Lab
4) Power Systems and Renewable Energy Lab
