Design of Free-Positioning Wireless Power Transfer using a Half-Rectangular Prism Transmitting Coil

Free-positioning wireless power transfer (WPT) system has been drawn attention in recent years. Traditionally, WPT system can transfer energy in one or two directions on the same plane leading to the restrictions of angle and axis misalignment between a transmitter and receiver coil. In this paper,...

Description
Summary:Free-positioning wireless power transfer (WPT) system has been drawn attention in recent years. Traditionally, WPT system can transfer energy in one or two directions on the same plane leading to the restrictions of angle and axis misalignment between a transmitter and receiver coil. In this paper, we propose a wireless power transfer system with a half-rectangular prism (HRP) transmitting coil for free-positioning. A small receiving coil is placed inside the transmitter to achieve the transferred energy through the magnetic resonant coupling. It is shown that the wireless power transfer system can charge in spatial freedom.
