摘　　要：针对无线电能传输WPT(wireless power transmission)系统耦合机构发生偏移时,输出电压波动的问题,提出1种基于恒压输出区间追踪的WPT系统抗偏移方法。首先,建立CLC-S型WPT系统的模型,分析该系统在谐振和非谐振状态下的互感与输出电压增益之间的关系,由分析可知,系统工作在非谐振状态下的恒压输出区间内抗偏移能力更强;然后,设计电感补偿序列,提出恒压输出区间追踪控制策略,实现WPT系统输出电压恒定控制,提高系统的抗偏移能力;最后,搭建仿真模型和实验平台,仿真及实验结果均表明,采用恒压输出区间追踪控制策略,可以有效减小输出电压的波动,验证了系统在强互感干扰下的鲁棒性。相较于无恒压输出区间追踪的WPT系统,所提系统具有更好的输出电压动态调节能力。An anti-offset method for a wireless power transmission(WPT)system based on constant-voltage output interval tracking is proposed to deal with the problem of output voltage fluctuation when the coupling mechanism in the WPT system is shifted.First,a model of a CLC-S WPT system is established,and the relationship between the mutual inductance and output voltage gain in resonant and non-resonant states of the system is analyzed.Based on the analysis,it is found that the system has a stronger anti-offset capability in the constant-voltage output interval when it works in the non-resonant state.Second,an inductance compensation sequence is designed,and a constant-voltage output interval tracking control strategy is proposed to realize the constant output voltage control of the WPT system and improve its anti-offset capability.Finally,a simulation model and a test platform were built,and simulation and experimental results show that the constant-voltage output interval tracking control strategy can effectively reduce the output voltage fluctuation,thus verifying the robustness of the system under strong mutual inductance interference.Compared with the WPT system without constant-voltage output interval tracking,the CLC-S WPT system has a better dynamic regulation capability of output voltage.
