中文摘要
本文研究了全向无线电能传输(WPT)系统,因其比平面系统具有更高的灵活性。文章选用LCCL-LC谐振变换器拓扑,利用其电流源特性,并将系统频率提升至兆赫兹(MHz)级别以增加空间充电自由度。
English Abstract
Recently, omnidirectional wireless power transfer (WPT) systems have been studied intensely, due to their improved flexibility as compared to their planar counterparts. The LCCL-LC resonant converter topology is selected due to its current source characteristics in this article. The system frequency is pushed to megahertz (MHz) to increase the spatial charging freedom. In a megahertz WPT system, t...
