摘要：

Cross coupling between multiple receivers can lead to significant impacts on the characteristics of multi-receiver wireless power transfer (WPT) systems. To improve the power transfer capability, performance and reliability of such systems, mathematical models needs to be derived and employed for parameters design. This paper builds a small-signal model that describes how a typical multi-receiver WPT system reacts on a perturbation in its reference control signal using the methods of generalized state space averaging (GSSA) and extended description function (EDF). The small-signal model is verified by simulation results of PSIM software and proves to be accurate. Using the derived model, the dynamics of the system is analyzed and then its parameters are designed and optimized.
