摘要:
      为实现感应耦合电能传输(ICPT)系统在负载及气隙变化时的输出电压和工作频率恒定,提出了一种采用CCL/LCC复合谐振网络的电流型ICPT系统。首先,在基波条件下,依据变压器漏感模型建立系统等效电路,得到了输出电压增益与输入阻抗的表达式;然后,通过系统参数优化设计,推导出了动态负载下系统恒压供电和谐振工作频率稳定的条件。另外,当气隙变化时,利用动态调谐技术重新补偿耦合电感,可使得输出电压和工作频率在气隙变化前后保持不变。系统特性分析表明,所提出的CCL/LCC复合谐振网络电流型ICPT系统,在负载和气隙变化时可以保证输出电压和工作频率稳定。最后,实验验证了理论分析的正确性和有效性。
Abstract:
      In order to achieve constant output voltage and operation frequency of the inductively coupled power transfer(ICPT)system when the load and the air gap vary, this paper proposes a current-type ICPT system with the CCL/LCC composite resonant network. Firstly, under the fundamental harmonic condition, the system equivalent circuit is established according to the transformer leakage inductance model, and the equations of the output voltage gain and the input impedance are obtained. When the load varies, the conditions of constant-voltage supply and stable operation frequency are derived by system parameter optimization. In addition, when the air gap varies, the dynamic tuning technology is used to compensate the coupled inductor again, to achieve constant output voltage and operation frequency before and after the air gap changes. The analysis of system characteristics shows that the proposed ICPT system can achieve constant output voltage and stable operation frequency when the load and the air gap vary. Finally, the correctness and effectiveness of the theoretical analysis are verified by experiments.
