This paper presents a new optimal design of the resonant networks in terms of output voltage sensitivity respect to misalignment. For both stationary and dynamic electric vehicle charging applications, the misalignment which is the variation of mutual coupling is inevitable. The variation of coupling factor affects the output voltage and efficiency of the wireless charger system. Therefore, output voltage sensitivity respect to the variations of the coupling factor is one of the major system performance indexes. The other main parameter is the efficiency of the wireless charger system in a wide range of coupling variations. In this paper, two different objective functions are defined to address the desired design requirements. Moreover, a framework for the design and optimization of the compensation topologies is presented. Efficiency and output voltage of each topology is compared for each objective function. Finally, the best candidates for each case are selected.
