Abstract: The application provides a gear control circuit and system for an alternating current motor. The gear control circuit includes: a plurality of controllable switches; a detection unit, configured to detect switching statuses corresponding to the controllable switches; a gear input unit, configured to receive a target gear m inputted from outside; and a control unit, connected to the gear input unit and configured to obtain the target gear m. The application also provides a switch controller and an electronic device. The switch controller includes a signal modulation circuit, a signal follower circuit, a comparison circuit, and a switch control circuit. The switch controller may perform digital-to-analog conversion by using the signal modulation circuit, to modulate a first PWM signal being a digital signal into a second PWM signal being an analog signal, and then the signal follower circuit performs load amplification on the modulated second PWM signal.
