Design of a Feedback-Controlled Wireless Converter for Electric Vehicle Wireless Charging Applications


Electric vehicles (EVs) have played an important role in the modern transportation system in recent years. However, current generations of EVs face unsolved drawbacks such as short driving range, long charging time, and high cost due to expensive battery systems.  Wireless Power Transfer (WPT) is a promising technology that is able to mitigate the drawbacks EVs are facing. This paper focuses on investigating and building a complete high-efficiency WPT system that is capable of efficiently charging electric vehicles. The goal is to design and apply two different configurations of compensation networks to the WPT system. In this paper, the two compensation network configurations studied are LLC (inductor, inductor, and capacitor) and LCC (inductor, capacitor, and capacitor). After comparing their operational characteristics and efficiencies, the most suitable configuration is proposed. Moreover, a phase-shifted controller is applied in order to regulate the power transferred through the WPT system.



Dr. Mohamed Badawy is an Assistant Professor in the Electrical Engineering Department at San Jose State University. He joined the department in Fall 2016 as an assistant professor. Dr. Badawy is the director of the Center of Power Electronic Converters (CPEC) that he established after joining the department. The CPEC serves the research needs in the power electronics area, and it supports the power electronic classes in both undergraduate and graduate levels. Dr. Badawy research interests span the areas of power electronic configurations and control structures for advanced applications and technologies such as: electric vehicles (EVs) and renewable energy systems. Dr. Badawy was an awardee for several grants from National Science Foundation, the Department of Transportation and the Department of Energy in addition to his continuous collaboration with industrial partners in terms of sponsored projects (Delta Electronics, EiQ Energy, OPAL-RT, Texas Instruments, etc…). Dr. Badawy is an active IEEE member as he is an associate editor for IEEE-IAS Transactions, and a reviewer for several IEEE conferences and Journals. Dr. Badawy had been on the organizing committee of several IEEE international conferences such as IEEE COMPEL and IEEE ECCE.
