Abstract：This paper focus on the high parameter sensitivity problem of ECPT and investigates the system voltage gain variation affected by the quality factor,the ratio of inductances in the LCL network,and the ratio of capacitances on system performance with the help of the voltage transfer function modelled by the impedance transformation principle.The optimum value ranges of the four system parameters,which ensures that the system voltage gain variation is no more than 40%,are presented and thus realize the low parameter sensitivity of high order ECPT system.Finally,the validity of the voltage transfer characteristic and the feasibility of the parameter ranges are verified by experiment results.The research provides a theoretical reference for the system design.
