报告摘要：Wireless power transfer (WPT) using inductive resonance has become increasingly popular in recent years. Now this emerging technology is being applied to charge wearable devices, cellphones, household appliances, electric vehicles, and even very high-power trains. Currently WPT working at kilohertz shows rapid improvement thanks to the new development in power electronics. Meanwhile, it is attractive to further increase the resonance frequency such as to several megahertz (MHz) especially for a higher level of spatial freedom, namely a longer transfer distance and higher tolerance to coupling coil misalignment. A higher frequency also helps to build more compact and lighter WPT systems. Therefore, WPT systems working at MHz are now widely considered to be suitable for low-power applications. This presentation will provide an overview of megahertz wireless power transfer. It will discuss the general issues and solutions for a 2D WPT system, such as: maximum efficiency point tracking, multiple-coils coupling mechanism, cross coupling compensation, and power distribution among multiple receivers. Finally, a 3D WPT system is proposed to further improve the user experience for charging small portable devices.
