摘　　要：LCL型非接触电能传输系统在高频运行过程中,负载的变化会导致输出电压不稳定。针对此类问题,建立了系统的动态模型,对电路交流变量进行复数分析,设计了一种基于自调整模糊控制算法的功率控制策略来控制原边逆变全桥脉冲的相移角,以保证系统输出电压随期望电压而变化。仿真结果表明:负载发生变化时,该控制器可以有效地使系统输出电压恒定;负载不变时,能够使系统输出电压达到期望值。The output voltage of the LCL resonant inductive coupled power transfer（ICPT）system may be unstable inthe high-frequency operation when the load changes. For such problems,the dynamic model of the system was estab-lished. In order to ensure that the output voltage of the system could change with the desired voltage,a self-adjustingfuzzy control strategy was designed to control the primary side full-bridge inverter pulse phase shift angle. The simula-tion results show that when the load changes,this control method can effectively make the output voltage constant by ad-justing the primary side full-bridge inverter pulse phase shift angle,and when the load is constant,the output voltagecan be controlled with the desired voltage.
