Abstract: 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.

Key words: electric vehicle, wireless power transfer, power transfer control, rectifier circuit, passivity-based control
