Optimization of the compensation networks for WPT systems

Performance of wireless power transfer systems are greatly influenced by the topology and the sizing of the compensation networks connected to the coils and number of design procedures have been proposed to optimize one or the other characteristic of the system acting on their parameters. This paper introduces a method base on an optimization algorithm to design the compensation networks with the objective of optimizing the power transfer efficiency and the amount of transferred power for a given supply voltage amplitude. The soundness of the method has been checked comparing the obtained results with those achieved analytically in the case of the simple SS compensation topology, and checking by means of amplitude Bode diagrams the outcomes relevant to more complex topologies.
