With ever increasing pollution from use of fossil fuel and their ever depleting resources for energy source, the need for more eco-friendly renewable energy source is more imperative than ever. Moreover with integration of human society into a Global Village, the use of IT network and computing devices is ever increasing. Now is the high-time to accomplish a self-sustained eco-friendly human society for us and our future generations, which is primarily powered by renewable energy sources which will save our planet Earth from ecological destruction. To do so, the need for high efficiency reliable electrical power conversion systems for harnessing electrical power from renewable energy sources like PV and wind, driving electric vehicles and eco-friendly IT networks is more important than ever. Power Electronics is that field of electrical engineering which deals with solid state electrical power conversion systems. It is a multi-disciplinary field involving knowledge of semiconductors both low and high power, electro-magnetics, control theory etc. This presentation will give you some basic knowledge about how power electronic energy conversion systems work, and introduce you to some of his previous and on-going work on power converters for various industrial applications like data-centers, LED lighting, E-actuation in More Electric Aircraft, Battery Charging in Pure Electric Vehicles, PV energy harnessing etc. Based on his experience gained through research projects he would introduce his research vision on power electronics for a GREENER ECOFRIENDLY future.

Pritam Das was born in Calcutta, India in 1978. He received the Bachelor of Engineering Degree in Electronics and Communication Engineering from the University of Burdwan, India. He also received the Master’s of Applied Science Degree and the Ph.D, both in Electrical Engineering from the University of Western Ontario, London, ON, Canada in 2005 and 2010 respectively. He was a recipient of Ontario Graduate Scholarship all throughout his Ph.D studies in the University of Western Ontario. From 2010 to 2011, he was a post-doctoral fellow at the Queen’s Centre for Energy and Power Electronics Research (ePOWER), Queen’s University Kingston, Ontario, Canada. As a post-doctoral researcher at Queens University he was also involved in a Freescale sponsored project for plug-in Electric Vehicles developed by Peugot (PSSA), France. He was also with Murata Power Solutions, Markham Ontario, where was involved in research and development of high power converters conforming to 80Plus.Org Platinum efficiency standards for powering network servers, data centers, telecom devices for Cisco, Alcatel Lucent etc. Since 2013 he is an Assistant Professor in the Department of Electrical and Computer Engineering, National University of Singapore where he is actively researching on Power Converters for industrial applications which include data centers, LED lighting, E-actuation in More Electric Aircrafts, harnessing solar energy, energy storage in Smart Grid etc. His research has attracted funding of more than 1Million Singapore Dollars. He is involved in teaching courses on Power Electronics for bachelors, masters and Ph.D students. He has also founded Powereff, a power solutions company. His research interests include high frequency and high efficiency ac-dc and dc-dc power converters, power factor correction, soft switching techniques, design of high frequency magnetic components for power converter and modeling and design of control of ac-dc and dc-dc converters, application of wide band gap devices in power converters etc. He has published over 65 technical papers in leading IEEE journals and conferences. He has also two applied US patents. He is a reviewer of IEEE Transactions on Power Electronics, IEEE Transactions on Industrial Electronics, IEEE Transactions on Industrial Informatics, IEEE Journal on Emerging and Selected Topics in Power Electronics.
