Combination of Sensorless Energized Section Switching System and Double-LCC for DWPT

Abstract

Dynamic Wireless Power Transfer (DWPT) systems can improve cruising range and reduce the capacity of the battery of electric vehicles. DWPT system is required to achieve high efficiency of power transmission without complex circuits or control. In this study, a new DWPT system that combines sensorless energized section switching and double-Lee topology is proposed. It can transmit power safely by using Double-Lee topology and efficiently by using an energized section switching system with a sensorless vehicle detection method. The effectiveness of the proposed systems was verified by experiments.
