Analysis of Contactless Power Transfer System Using Generalized State Space Averaging Method

Abstract:

According to system switching nonlinear characteristic,the paper utilizes generalized state space averaging (GSSA) method,decomposes system model in frequency domain and transform system nonlinear model to approximate linear continuous model.With the model,system static and transient dynamic behaviors are analyzed in detail.Simulation results are consistent with SIMULINK model.Furthermore,system efficiency computing method is presented.And analyses among system efficiency,DC inductor and load parameters are proposed for system design as well.
