摘要

摘要: 针对无线电能传输系统中单个逆变器输出功率难以满足大功率应用需求的问题，研究了无线电能传输系统多路逆变器功率合成机理，通过建立基于2路逆变器功率合成拓扑结构的无线电能传输系统等效电路模型，得出了基于多路逆变器功率合成的无线电能传输系统的输出功率、传输效率规律。研究结果表明，基于多路逆变器功率合成的无线电能传输系统的输出功率、传输效率均由各支路逆变器共同承担，且因各支路功率驱动能力不同而在各支路互补转移分配；多逆变器功率合成后的系统特性与单逆变器工作时一致。

Abstract: For the problem that output power of a single inverter in wireless power transmission system could not satisfy large power requirement, power combination mechanics of wireless power transmission system based on multi inverters was researched. An equivalent circuit model of wireless power transmission system was built which was based on power combination topology of two inverters, and laws of output power and transfer efficiency of the system were obtained. The research results are as following. Output power and transfer efficiency of the system are shared by each branch inverter, and distributed in each branch complementarily because of different power driving ability of each branch. System characteristics of wireless power transmission system based on power combination of multi inverters is identical with that of the system based on single inverter.
