Peak efficiency and peak power point of wireless power transfer system for electromobility applications

The article deals with the analysis of series - series-compensated circuit for systems of contactless charging of electricity in electromobility applications. The article introduces an analysis of the transfer characteristics of the system depending on change of the distance and of the transmitted power. Mathematical analysis will be used for the purposes of implementation of simulation experiments. Operating points for different operating distances that are characterized by a maximum value of power efficiency and high value of the transmitted power are determined on the basis of simulation results. Confirmation of results of numerical and mathematical analysis through experimental verification is provided in the conclusion.
