There is a problem of magnetic leakage in the charging process of wireless power transfer systems, which can threaten human safety and affect the normal operation of electronic equipment. In this paper, the wireless power transfer system adopts a bilateral LCCS hybrid topology to address this problem. It proposes a magnetic field shielding suppression method based on the improved electric eel foraging optimization algorithm. Firstly, the Fuch infinite folding chaos strategy and the Cauchy–Gauss variation strategy are introduced to optimize the electric eel foraging optimization algorithm, which further improves the global optimal parameter search capability of the improved electric eel foraging optimization algorithm. Then, the improved electric eel foraging optimization algorithm is proposed to perform a parameter search for the inductance of the shielded coil. Finally, simulation and experimental verification show that when the shielding coil inductance is optimal, the method proposed in this paper can effectively shield and suppress the magnetic leakage of the system, reducing the magnetic leakage field by 67.05%. The magnetic induction intensity in the space region meets the international safety standards, which verifies the effectiveness and feasibility of the method. Full article
