Mutual inductance and load identification of dual excitation WPT

The dual excitation WPT system has a more complex system structure and system parameters than the single excitation WPT system. In this paper, based on the LCC-S topology, a steady-state circuit model of the system is established, the mathematical relationship between system circuit parameters and system identification parameters is obtained. Identification of system mutual inductance and load parameters is achieved by using Particle Swarm Optimization. Finally, the feasibility and effectiveness of parameter identification of the dual excitation system are verified by simulation and experimental results.
