Field – Circuit Model of Wireless Transmission Power System using Ω–T–T0 Formulation

The paper discusses the field-circuit model of the wireless power transmission system (WPTS) with the air-core high-frequency transformer. While working on the field model, a formulation which uses scalar magnetic potential Ω and electric vector potentials T and T0 was implemented. Model equations were provided. The system which consists of magnetically coupled coils connected with the elements of external circuits was taken into consideration. The selected results of simulation calculations were presented. The obtained results of simulation calculations were compared with the results of measurements obtained at a laboratory post
