摘要
传统的无线电能传输技术主要面向单向能量传输,随着无线电能传输技术应用领域的拓展,迫切需要双向无线电能传输(bidirectional wireless power transfer,BWPT)技术以实现无线充电设备间的能量交互。首先简述BWPT系统的基本工作原理,主要从BWPT系统的典型双向变换拓扑、谐振网络、同步控制技术、功率控制策略、软开关运行及其应用场景等方面论述其研究成果,分析电容式双向无线电能传输系统的发展现状和该技术亟待解决的关键问题,最后对BWPT系统未来值得关注的研究方向进行展望。
The traditional wireless power transmission technology mainly focuses on unidirectional power transmission.With the expansion of the application field of wireless power transmission technology,there is an urgent need for bidirectional wireless power transmission(BWPT)technology to realize the energy interaction between wireless charging devices.This paper first briefly describes the basic operating principle of a BWPT system,specifically discusses the main research achievements in terms of typical bidirectional conversion topologies,resonant networks,synchronous control techniques,power control strategies,soft switching operation and application scenarios of BWPT system,and analyses the development status of bidirectional capacitive power transfer system and the key issues that need to be addressed.Finally,prospects for research directions worthy of attention in the future are presented.
