Abstract：In order to regulate energy of contactless power transfer system which are usually high order nonlinear,a general stroboscopic mapping model is created based on fixed points theory and state-space method. The equations for calculating the periods and the steady-state waveforms are inferred,and the system working mode is presented using pulse density modulation. Then,the boundary condition equations are derived,based on which,the control parameters of PDM are given by numerical calculation. The soft switching is accomplished. Analysis shows that the current frequency is approximate under different pulse densities which is of benefit to pickup. Finally,the steady-state mode and its solution are verified by prototype and experiment.
