Aiming at the difficulty of configuration of resonance compensation topology parameters for LCC/S type wireless power transmission system

which makes it hard for the system to take into account both efficiency and output power

two objective functions are constructed based on system transmission efficiency and output power.These are two objective functions with non-linear relationship

which need to be combined with Pareto domination and particle swarm optimization（PSO）algorithm for optimizing calculation

to optimize the multi-objective parameters of LCC/S magnetic resonance coupling mechanism

so that the system can obtain sufficient power and obtain higher transmission efficiency at the same time.Availability of this algorithm is verified by simulation.
