|---|---|---|
The emergence of wireless charging for electric vehicles greatly facilitates automatic charging while increases the reliability of charging process. In this study, a 3 kW dual-source inductive power transfer system is investigated, specially optimized for large misalignment tolerance. A bipolar-solenoid inductive coupled transformer and closed-loop control strategies are introduced. To achieve constant current charging and maximized efficiency in transverse misalignment, control methods that employ primary-side phase shift H-bridge inverter and secondary-side buck converter are proposed. Simulation and experimental results validate the feasibility of the proposed control method. An experimental prototype is set up and a peak DC-DC efficiency of 87.3% is achieved at 200mm air gap, and a minimal efficiency of 81.5% is measured within 270mm misalignment. Overall, the proposed system structure and control method provides a practical method to overcome the main drawback incurred by misalignment, which is a significant efficiency drop outside the nominal operation point. |
