A design method of line commutated converter (LCC) compensation network for the dynamic wireless power transfer (DWPT) system based on a complex impedance model ( Z ‐model) of the input impedance of the rectifier is proposed in this study. The continuous conduction mode and discontinuous conduction mode (DCM) of the rectifier are analysed to calculate the equivalent input impedance of the rectifier. Based on the proposed model of the input impedance of the rectifier, a design method of LCC compensation network for the DWPT system is presented. Simulation results prove that the Z ‐model of the rectifier is more accurate than the prevailing resistive model. Experiments show that the DWPT system with the designed LCC network meets the requirement of the average output power with an average DC–DC efficiency over 93%.
