摘要：

In this paper a novel analytical calculation method of a wireless power transfer system for an inductive electrically excited synchronous machine is presented. By solving the differential equations of the parallel compensated secondary side, the nonlinear behavior of the passive rectifier in combination with the rotor winding load is analyzed. The time domain solution is used to convert the rectified load into an accurate equivalent impedance. Subsequently, the equations of the WPT system are derived. In contrast to conventional calculation methods the nonlinear behavior of the rectifier with its phase shift is considered. The effectiveness of the proposed approach is demonstrated by simulation comparison.
