Abstract：Inductively coupled power transmission(ICPT)systems have a wealth of topologies to choose from.These topolo-gies will have different effects on the output characteristics,and the analysis and optimization of the parameters of the topologies can also improve the output characteristics.In view of the above problems,the output characteristics of several simple topologies are sim-ply analyzed.Based on the LCL-P structure,the equivalent circuit schematic diagram is analyzed to obtain the equivalent AC im-pedance and excitation current value of each part,and then the expression of output characteristics is calculated.The improved par-ticle swarm optimization algorithm is used to optimize the variables in the expression,and the global optimal solution of a system is obtained by updating the inertia weight in real time,so as to improve the output efficiency of the system.The simulation results show that the improved algorithm system solves the phenomenon of premature convergence in the iteration process,has a high adaptabili-ty,reduces the inertia weight in the late iteration to fully search for the optimal solution,it can achieve the global optimization of multi-objective particles,has a more significant effect,and has a significant improvement in the system efficiency.
