摘　　要：针对多负载感应耦合电能传输系统中由于单向传输特性所产生的电能回馈困难与系统传输效率低下的问题,提出一种多负载感应耦合电能双向传输模式,以实现能量发射端与接收端之间的能量双向传输。阐述在软开关工作状态下运行于能量注入模式和自由振荡模式双工作模式的多负载感应耦合电能双向传输原理,并提出基于谐振软开关的多负载高频电能双向变换拓扑。以状态空间法构建并分析系统数学模型,通过仿真实验,实验结果论证了本文所提的多负载能量双向传输模式的可行性。To solve the issue of energy feedback difficultly and low efficiency brought by system open-loop running caused by unidirectional energy transfer in traditional inductive coupled power transfer （ICPT） system, a novel multi-load inductive coupled power bi-directional transfer mode was proposed to realize direct conversion between energy transmitter and receiver. The general principle about multi-load inductive coupled power bi-directional transfer based on energy injection mode and autonomous running mode was discussed, and at the same time, the topology of multi-load high frequency energy bi-directional transfer with resonant soft-switched technology was put forward to fulfill the energy hi-directional transfer requirement. Furthermore, the corresponding state-space model with energy injection mode and autonomous running mode and the topology parameters design method of resonant part for the maximum power transfer capability were analyzed. Finally, the simulation results validate the validity of multi-load inductive coupled power bi-directional transfer mode.
