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

Abstract: 

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.
