提出了一种适用于电动汽车动态无线电能传输系统原边和副边整流桥的无源控制方法，该方法可在原边、副边互感和负载波动情况下实现两边的功率因数校正和恒压控制。文中首先提出控制目标，建立了原边和副边整流桥的欧拉–拉格朗日 (E-L) 模型，之后结合动态无线电能传输系统的特点，设计基于 PI 校正整定值的无源控制律，通过在 Simulink 中的仿真验证了控制算法，最后搭建实验平台证明了控制方法的可行性。

A passivity-based control method for primary-side and secondary-side rectifier bridges of dynamic wire-less power transfer system for electric vehicle (EV) was proposed in this paper． It can realize power factor correc-tion and constant voltage control on both sides under the fluctuation of mutual inductance and load． Firstly，the control target was proposed，and the Euler-Lagrange (EL) model of the bridge was established． Then，based on the characteristics of dynamic wireless power transfer system，the passivity-based control law based on PI correction was designed． The control algorithm was verified by simulation in SIMULINK and the feasibility of the control me-thod was proved in the experimental platform．
