  "textContent": "A wireless power system receives an input voltage signal from a first node of a secondary side coil, comprises an active rectifier, a buck converter, and a linear charger comprising a first resistor, a second resistor, a third resistor, a mode switching circuit, a current mirror circuit. The active rectifier rectifies the input voltage signal to generate a rectified voltage signal. The first resistor couples between a first node point and second node point. The second resistor couples between the second node point and ground terminal. The third resistor couples between a third node point and ground terminal. The current mirror circuit outputs a reference current and charge current according to the rectified voltage signal and mode switching signal generated by the mode switching circuit. The buck converter outputs a first output voltage signal or second output voltage signal according to a first node point voltage.",
