Rectifier load analysis for electric vehicle wireless charging system.

The analysis of the rectifier-based load used for wireless charging systems for electric vehicle (EV) systems, as well as its various applications related to the design of on compensation networks and system loading estimation, are presented in this paper. In order to determine the values of input impedance, which contain both types of components— resistance and inductance—and may be estimated independently by the rectifier circuit parameters, a rectifier load based model structure is first developed. The design of a compensation network is then suggested based on an examination of rectifier load. Additionally, a methodology for secondary side load estimation and one for primary side load estimation are proposed, both of which use simply voltage measurements and call for an examination of the impact of the load connected at the rectifier.
