摘要
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 {right arrow over (Z)}=(Z1, Z2, . . . , Zm−1, Zm), 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).
