Evaluation of Omnidirectional Receiving Performance of Magnetic Coupled Feeding by 3D Spherical Winding-Receiving Coil and Multi-Rectification
Hideaki Abe WPT2017-78
Abstract (in Japanese) (See Japanese page) 
(in English) Contactless power supply is being studied from a variety of perspectives. The authors have studied new possibilities of simple contactless power feeding systems that can be placed. This is a research that can suppress the fluctuation of the receiving voltage by eliminating the non-feeding point even if the device is placed at an arbitrary inclination or direction with respect to the transmission coil face. As a result, three windings perpendicular to the spherical surface are wound, and each output passes through each rectifier circuit and is independently connected, enabling omnidirectional power reception. In this paper, firstly, the magnetic characteristics of each coil with respect to the inclination angle from the reference position of the 3D winding coil were examined. In addition, the three-coil output was independently rectified and the load voltage characteristics were examined by the difference between series and parallel connections after rectification. As a result, it proved that the parasitic point is eliminated and the voltage fluctuation becomes small in both cases.
