Design and Analysis of a Three-Phase Dynamic Wireless Power Transfer System for Heavy-Duty Electric Vehicles Considering Misalignment

Designs for two versions of a 200-kW-output three-phase dynamic wireless power transfer (DWPT) system are presented in detail: one using a Magment-core transmitter and one using a coreless transmitter. Critical performance metrics are compared for both designs, including total system losses, total mass/volume of compensation circuit components, and stray magnetic field. A series of time-domain simulation studies are shown to verify basic operation of the proposed DWPT systems throughout a charging event. The effects of misalignment on the performance of the two designs are examined.
