基于直流输入电流和移相角的无线电能传输系统负载参数联合辨识

This article presents a multiple load parameter joint identification method, adopting only the measured dc input current and inverter phase-shift angle of the wireless power transfer (WPT) system. First, a WPT fundamental-harmonic model is established, considering the effects of the battery and rectifier load. This model can quantitatively describe WPT characteristics and parameter relationships a...
