Gautam Rituraj, Ph.D.

Interests

Research interests include analysing and designing the wireless charging coils and developing the power electronic circuits in the WPT system for charging of EVs. Furthermore, I am interested in developing the charging strategies for wired and wireless charging system to extend the battery life. Apart from that, it includes the design and development of the smart solar home system with multiple charging strategies for rural areas in India. At my leisure, I used to explore the technological advancements in the related field that helps me to refine the research work.
