Abstract
In this paper, we propose a new SiC-VMOSFET single-ended converter that realizes a low-cost, compact and lightweight wireless EV charger, which is the key device for the popularization of electric vehicles in recent years. A three-fold transfer power and 1/6 power device loss have been achieved by an improved drive pattern, a newly developed V-groove trench SiC-MOSFET, and a new type of low switching loss circuit topology.
