Abstract |
Recently, wireless power transfer (WPT) system is widely studied. WPT system is very attractive because it removes power cables from home appliances, office equipment and battery chargers for electric vehicle. However, pickup's posture affects the performance greatly. In this paper a new pickup system whose output voltage is less sensitive to its posture is proposed. The proposed pickup system is composed of three coils perpendicular to each other. A prototype is constructed and tested, and its usefulness is verified. |
