Methods for Parameter Identification, Load Monitoring and Output Power Control in Wireless Power Transfer Systems

Summary

A method for identifying impedance related parameters in a wireless power transfer (WPT) system including n coils is disclosed. Said method includes determining optimum values of the impedance related parameters based on a set of measured input impedance by applying an evolutionary algorithm to solve optimum solutions. Wherein the set of measured input impedance includes an input impedance vector (I), each input impedance in the vector (Zk) measured at different frequencies fk,(k＝1, 2, …m); and the impedance related parameters includes dll+1 representing a distance between the l-th coil and the l+1 coil (l＝ 1, 2, …n-1) and Ci representing a capacitance of the capacitor connected to the i-th coil (i＝1, 2, …n).
