Abstract

Wireless power transfer (WPT) is a device that transmits electrical energy from a power unit to an electrical load through the air wirelessly or without the interconnection of any conductors. The designs of current WPT are quite large and inappropriate for many applications, especially for electronic devices. The small scale (mid-range WPT) with 1 meter distance was investigated to develop a wirelessly transmitted energy for the use of electronic devices, particularly to charge portable devices. The distance of a mid-range WPT can be increased by placing the resonators between the transmitter and receiver to achieve the 1-meter distance of the WPT. The power transfer efficiency (PTE) was significantly enhanced when the resonators was placed. The high efficiency was maintained due to the increasing distance of the WPT. As a result, more power can be transmitted from transmitter to the receiver respectively.

利用继电器效应的磁共振耦合设计与优化
无线电力传输(WPT)是一种将电能从动力单元通过无线或不需要任何导体互连的空气传输到电气负载的设备。目前WPT的设计相当大,不适合许多应用,特别是电子设备。研究了1米距离的小规模(中程WPT),以开发用于电子设备的无线传输能量,特别是为便携式设备充电。通过在发射器和接收器之间放置谐振器,可以增加中程WPT的距离,以实现WPT的1米距离。当放置谐振腔时,功率传输效率(PTE)显著提高。由于WPT的距离增加,保持了较高的效率。因此,可以从发射机分别向接收机传输更多的功率。
