摘　　要：针对CPT(ContactlessPowerTransfer)系统负载切换时造成输出电压不稳定问题,分析了CPT系统输出电压调压方法,提出了通过调节输入电压来控制输出电压的主动控制方法。通过分析及数学推导,建立了拾取电路的等效电路模型以及CPT系统电路的阻抗模型,进而建立了输入电压与输出电压的关系模型,通过实验验证了该模型以及主动控制方法的有效性。For the output voltage instability problem caused by the contactless power transfer （CPT） system load switching,the output voltage regulator method of the CPT system was analyzed,and the output voltage active control method adjusted by the input voltage was proposed.Through the analysis and the mathematical reasoning,a DC equivalent circuit model of pick-up circuit as well as the impedance model of CPT system circuit was established,thus the relational model of input voltage and output voltage was set up.And the experiment shows that the model and active control method is highly effective.
