This paper deals with basic parameters of contactless power transfer (CPT) and modelling of CPT in FEM analysis software. There are described basic equations for comput- ing parameters of CPT components. The main part of this paper refers about creating CPT transformer model in multiphysics software Maxwell Ansys to determine basic CPT parameters such as induction and impedance of CPT transformer, its electromagnetic field and its effect on surroundings. CPT operates at high frequencies so its electromagnetic compatibility with other electric devices is very important because it may cause serious risks of fail of devices such as pacemakers or communication devices.
