A Single-Ended 6kW Wireless V2H with a New Asymmetric Power Transfer Coils for Offset Position Operation

Abstract

In this paper, we propose a wireless V2H system using a new structure of asymmetric transfer coils with a small variation of coupling coefficient against the misalignment between the feeding and receiving coils. Conventional bi-directional wireless V2H systems consist of a bridge converter which is large and high-cost device. In this study, wireless V2H is configured with a single-ended converter that operates with a single power device to achieve a compact and low-cost system. Single-ended converters have a problem that they do not operate stably when the coupling coefficient fluctuates greatly. Therefore, developed have new structure asymmetric transfer coils with less fluctuation of coupling coefficient to realize a compact, lightweight and low-cost single-ended wireless V2H system.
