摘要
        Due to the large number of dynamic components and the complexity, the dynamic modeling of wireless power transmission(WPT) systems has always been a difficult problem. The generalized state-space average(GSSA) modeling method is suitable for wireless power transfer systems because of its fast time-varying characteristics. Based on this, Fourier coefficients and switching functions is introduced to connect the state variables of the circuit with the generalized state variables, a large-signal model of the Quasi-Z-source WPT system is established in the shoot-through and phase-shift control mode, and the transfer function model of the system is further derived with the help of the small-signal perturbation method. The model is used to analyze the steady-state and dynamic characteristics of the system, which provides an important reference for the design of the system controller. In this paper, an experimental platform for wireless power transfer system using Quasi-Z-source converters is built, and the basic principles and theoretical models of the system are experimentally verified through digital PI controllers. The results show that the theoretical model has sufficient accuracy.
