Year: 2025

Type: article

Abstract: To address the issues of frequency detuning and the difficulty of simultaneously optimizing efficiency and cost in magnetic resonance wireless power transfer (MR-WPT) systems under composite interference, this paper proposes a fuzzy-PSO hybrid frequency tracking algorithm and constructs a three-dimensional topology evaluation model and a dual-objective optimization framework based on efficiency, stability, and cost. Simulation results demonstrate that the proposed hybrid algorithm reduces frequency tracking error by over 30% compared to traditional methods and improves convergence speed by 40%. The three-dimensional evaluation model identifies the optimal application scenarios for S-S, S-P, and P-P topologies. Genetic algorithm optimization achieves a 15% increase in system efficiency and a 20% reduction in cost. This study provides effective algorithmic strategies and design guidelines for the industrialization of MR-WPT systems.
