Abstract: A fan control circuit includes a hardware controller, a rectifier circuit, first to third electronic switches, and a fan. When the hardware controller outputs a pulse width modulation (PWM) signal to the rectifier circuit and the fan, the rectifier circuit transforms the PWM signal into a direct current (DC) voltage and outputs the DC voltage to the first electronic switch.

A rotation speed of the fan is controlled by the PWM signal received from the hardware controller. When the hardware controller does not output the PWM signal, the first electronic switch is turned off, the second and third electronic switches are turned on, a DC power supply supplies power to the fan through the third electronic switch, and the fan rotates at full speed.
