摘　　要：针对感应耦合电能传输系统负载切换时输出电流不稳定问题,提出一种用于恒压输入、恒流输出的二次侧补偿网络。该补偿网络将松耦合变压器及补偿元件等效为导抗变换器,不仅可以实现输出电流与负载无关,而且可以保证系统处于完全谐振状态。依据互感模型,利用二端口理论建立了系统的阻抗模型,推导了输出电流与输入电压关系,给出了整个系统实现输出恒流以及单位功率因数输入的参数配置方法,并分析了主要参数对系统性能的影响。另外,对系统参数进行了优化设计,以便减小装置体积,降低成本。仿真与实验结果证明了理论分析的正确性。To maintain the stability of output current from an inductive coupled power transfer(ICPT)system under switching load,a novel compensation network is proposed on the secondary side to realize constant output current under constant voltage input.The loosely coupled transformer and compensating elements are regarded as an immittance converter,thus this compensation network can not only realize the output current which is independent of loads,but also ensure the system to be in a complete resonance state.First,according to the mutual inductance model,an impedance model is established using the two-port theory,and the relationship between output current and input voltage is deduced.Then,a parameter configuration method for the whole system is given to realize constant output current as well as unit power factor input,and the influence of main parameters on the system performance is also analyzed.Furthermore,the system parameters are optimized for minimizing size and lowering cost.Finally,the validity of the theoretical analysis was verified by simulation and experimental results.
