Description

technical field [0001] The present invention relates to the technical field of integrated filter modeling, and more specifically, relates to a V2G system integrated filter modeling method. Background technique [0002] V2G (Vehicle To Grid) refers to connecting the power battery of an electric vehicle to the grid through power electronic devices to realize the bidirectional flow of electric energy between the grid and the battery. Traditional inductors generally have the problem of large volume, which hinders the further reduction of V2G systems. Integrated inductors based on motor winding multiplexing have received a lot of attention from researchers. This integrated filter was first patented by Rippel and Cocconi in the United States. [0003] Since the integrated filter uses the motor stator as the iron core, it is easily affected by nonlinear factors such as motor saturation and space harmonics, so the integrated inductor has strong nonlinearity. Nevertheless, most of...
