Pareto fronts for coils' efficiency versus stray magnetic field in inductive power transfer
Coils' efficiency and stray magnetic field should be optimized together when designing coils for inductive power transfer. Multi objective optimization using Pareto front is a suitable method. It also provides a straightforward and accurate insight of the relationship between coils' efficiency and stray magnetic field since all the solutions along the fronts are optimized structures. In this paper, Pareto fronts for coils' efficiency versus stray magnetic field are used to design coils and investigate efficiency field relationship for inductive power transfer with different air gaps between transmitter and receiver coils. Procedure to derive the Pareto fronts based on parametric sweep in finite element simulation is also demonstrated. Accuracy of FES is validated with experiment.
