ELECTRONIC DEVICE AND CONTROL METHOD THEREFOR

An electronic device and a control method for the electronic device are provided, and relate to the field of wireless charging technologies, to improve compatibility of a power receiving terminal device in wireless charging with a power transmitting terminal device by improving ASK communication quality. The electronic device includes a device circuit (), a voltage conversion circuit (), a rectifier circuit (), a resonant circuit (), and a modulation circuit (). The resonant circuit () includes a resonant inductor (L) and a resonant capacitor control circuit (ci) connected in series to the resonant inductor (L). A first end of the resonant inductor (L) is coupled to the rectifier circuit (), a second end of the resonant inductor (L) is coupled to a first end of the resonant capacitor control circuit (ci), and a second end of the resonant capacitor control circuit (ci) is coupled to the rectifier circuit ().
