Multi-objective optimization of parameters for magnetically coupled resonant wireless energy transmission systems

To improve the transmission efficiency and output power of a magnetically coupled resonant wireless energy system, this paper proposes multi-objective optimization method based on analytical expression improved NSGA-II algorithm. First, expressions electrical performance parameters in mechanism are derived. On basis, mathematical model is established, with size, many turns, wire diameter transmitting receiving coils as design variables; frequency distance between coils, load size constraints; objectives. Then solved by algorithm to obtain Pareto optimal solution. Finally, physical system built verify correctness simulation experiment reliability experiment. This study instructive for optimizing system.
