Fundamentals of Power Electronics

I received the B.Sc. degree (Hons.) in physics from St. Stephen’s College, Delhi (India) in 1985; the integrated M.E. degree in electrical engineering from the Indian Institute of Science, Bangalore, India, in 1990; and the Ph.D. degree in electrical engineering with specialization in power electronics from the University of Victoria, British Columbia, Canada, in 1994. After a brief stint with Statpower Technologies, Burnaby, Canada, as a Research Engineer during 1994–1995, I joined the Department of Electrical Engineering, Indian Institute of Technology–Bombay, Mumbai, India, where I am currently a Professor. I mainly work in the field of power electronics with focus on power quality issues, renewable energy conditioning, and microgrids. I serve on the editorial boards of the IEEE Transactions on Power Electronics, IEEE Transactions on Industry Applications and IET proceedings on Renewable Power Generation. I am a past editor of the IEEE Transactions on Smart Grid. I am a fellow of the Indian National Academy of Engineering (INAE), the Institution of Electronics and Telecommunication Engineers (IETE) and IEEE.
