To address the issue of metal foreign objects interfering with the charging area and causing a significant drop in the Wireless Power Transfer system’s output power, a method to suppress their influence is proposed. First, a circuit model with detection coils is established, the system’s coupling mechanism is analyzed, a mathematical model for output power is derived, and mutual inductance deviation measure is quantified. Next, a finite element simulation model with detection coils is created to simplify the coil design and analyze mutual inductance deviation measure caused by various metal foreign objects. The misalignment of transmitter and receiver coils are considered, and an improved Grey Wolf Optimizer is introduced to optimize compensation topology parameters, targeting output power. Finally, a simulation model and experimental platform are built, and the proposed method is verified through simulation and experimentation. The method can achieve optimal output power in limited iterations while satisfying constraints, confirming its correctness and effectiveness. |
