    Abstract: A wireless power transfer (WPT) system for an electrical vehicle (EV) may include a ground assembly (GA) having a GA transmitter coil, a vehicle assembly (VA) having a VA receiver coil magnetically coupled to the GA transmitter coil, a compensation strategy stage including a parallel-series compensation network to obtain a voltage VVA in the VA receiver coil proportional to an effective current Ip_rms in the GA transmitter coil, a rectifier in the VA to obtain a continuous voltage Vdc_VA, and a control strategy stage with a voltage control loop and a current control loop. The control strategy stage may provide a control command to regulate voltage in the VA to adjust the continuous voltage Vdc_VA based on a reference DC link voltage. A DC link of a conductive charger of the EV may be regulated with the adjusted continuous voltage Vdc_VA during an inductive charging process of the EV. The rectifier may be connected to the DC link of the conductive charger of the EV.
