Magnetic Design for Three-Phase Dynamic Wireless Power Transfer With Constant Output Power


This paper details the design of a three-phase transmitter-receiver topology for use in a dynamic wireless power
transfer (DWPT) system for heavy-duty electric vehicles. The proposed approach eliminates the power oscillation and voltage/current sharing problems that plague planar three-phase DWPT systems. Multi-objective optimization is employed to maximize magnetic coupling and minimize undesired positive–negative sequence coupling. Selected designs are simulated for a 200-kW/m DWPT system, verifying the elimination of power oscillation and phase imbalance with minimal impact on magnetic performance. A prototype DWPT system is designed, and low-ripple power output is demonstrated at 52-kW operation.
