WIRELESS CHARGING RECEIVING CIRCUIT, CONTROL METHOD AND TERMINAL DEVICE

This application discloses a wireless charging receiver circuit, a control method, and a terminal device, and relates to the wireless charging field, to compensate for, to some extent, decreases in an output voltage and an output power of the wireless charging receiver circuit due to a great increase in a transmission distance between a secondary coil in the wireless charging receiver circuit and a primary coil in a corresponding wireless charging transmitter circuit. The wireless charging receiver circuit includes N capacitor-switch networks (200), a rectifier circuit (300), and a controller (CTRL), where N is an integer greater than or equal to 1. A first end of each capacitor-switch network (200) is connected to a first input end of the rectifier circuit (300), and a second end of each capacitor-switch network (200) is connected to a second input end of the rectifier circuit (300). The controller (CTRL) includes N output ends. The N output ends one-to-one correspond to the N capacitor-switch networks (200), and each output end is configured to be connected to a control end of a first controllable switch device (Sn) in a corresponding capacitor-switch network (200) and a control end of a second controllable switch device (Sn') in the corresponding capacitor-switch network (200).
