Abstract
Remote Electric Vehicles (EV) charging could become a viable alternative to cable systems. This paper is dedicated to the ana lysis of the Strongly Coupled Magnetic Resonance (SCMR) serial-to-serial topology aimed at establishing the impedance matching and obtains the maximum efficiency and power transfer coefficient. The research was done by using a model of equivalent circuits, experimental investigation and finite-element modeling of the mutual inductance. Upon generalizing the results obtained from the analytical and experimental research as well as 3D modelling of magnetic fields using Comsol Multiphysics, the interrelationships between internal resistance of voltage source and load resistance, characteristic and loss resistances as well as the distance between coils (the strength of magnetic coupling) necessary to ensure maximum efficiency and power transfer coefficient were established. The results of exp erimental research and modelling of the active power transfer coeff icient were presented.
