Gautam Rituraj, Ph.D.

Former Ph.D. student of E-Mobility Lab, Department of EEE, IIT Guwahati-781039, Assam, India.

I earned my Ph.D. degree at the Electronics and Electrical Engineering (EEE) Department, IIT Guwahati, India. I developed various approaches to maximizing the transmission efficiency (TE) and power transfer capability (PTC) of the wireless power transfer (WPT) system for EV charging applications, which are well documented in my PhD thesis. Currently, I am actively looking for job opportunities.

Thesis Supervisor: Dr.ing. Praveen Kumar, Professor, Dept. of EEE, IIT Guwahati.

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.
