Abstract
Methods and systems for dynamic wireless power transfer to charge an electric vehicle (EV) in motion are provided. The method can include: transmitting wireless power from a plurality of main transmitter coils; transmitting wireless power from a assisted coil disposed between each pair of adjacent main transmitter coils; receiving the wireless power at a receiver coil when the electric vehicle is charged in motion; providing a primary compensation network coupled to the main transmitter coils and the assisted coils; and compensating for reactive power at a secondary side by a secondary compensation network coupled to the receiver coil. Dimensions and positions of the assisted coils and parameters of the compensation network are configured to maintain a substantially constant mutual inductance profile between the transmitter coils and the receiver coil when the electric vehicle is charged in motion, thereby reducing power pulsation and providing a stable output voltage to the battery of the EV.
