Optimization of Resonance Parameters for Wireless Energy Transmission Systems With Bilateral LCC Resonant Circuits

The wireless energy transmission system is suitable for special occasions to replace the traditional wired power transmission method due to the elimination of cable connection. The wireless energy transmission system using magnetic inductive coupling with bilateral LCC resonant network can improve the power and efficiency of the system. In this paper, a mathematical model of wireless energy transmission system based on bilateral
$LCC$
resonant network is established according to the working principle of the system, and under the condition of meeting the electrical performance indexes of the system (e.g., voltage, power, etc.), a dual-objective optimization objective function of minimizing the volume and weight is constructed, and the NSGA-II algorithm is used to find an optimal solution to the objective function. Through comparison experiments with other optimization algorithms, it is found that the NSGA-II algorithm has excellent performance in terms of solution accuracy and convergence speed in solving the problems targeted in this paper, which can better break through the limitations of local optimal solutions. The results of this paper provide a theoretical and numerical analysis basis for the miniaturization and lightweighting of transmission devices.
