摘要
在无线电能传输过程中,航天仪器不可避免地会出现发射机构与接收机构位置偏移,这会使功率及效率发生骤减。为了解决这个问题,基于双十字组合式线圈偏移适应性,提出了具有抗偏移性的LCC-LCC及S-S拓扑并联构成的混合拓扑无线电能传输系统。首先,通过COMSOL有限元仿真,分析了机构的磁场分布特性;然后,对LCC-LCC与S-S补偿并联混合拓扑的电路特性及发生偏移振动等条件下的特性进行了分析;最后,通过仿真及实验,验证了所采用的双十字线圈与失谐混合拓扑下无线电能传输系统抗偏移的可靠性与有效性。实验表明:接收线圈在位置偏移下,系统的输出功率与传输效率基本保持不变。
In the process of wireless power transfer,the position misalignment of the transmitter and receiver for aerospace instruments is inevitable,which decreases the power and efficiency sharply.To solve this problem,a misalignment tolerant hybrid topology WPT system consisting of LCC-LCC and S-S topologies parallel is proposed based on the misalignment insensitive double-cross coil.Firstly,COMSOL finite element simulation is used to analyze the magnetic field distribution characteristics of the mechanism.Then,the circuit characteristics of LCC-LCC and S-S compensated parallel hybrid topology and the characteristics of vibration misalignment are analyzed.Finally,the reliability and effectiveness of misalignment tolerance using the double cross coil and detuned hybrid topology WPT system are verified by simulation and experiment.The experiment results show that the output power and the transmission efficiency of the system under the position misalignment of the receiver coil basically remain unchanged.
