PULSE WIDTH MODULATION FAN CONTROLLER |
摘要 |
A pulse width modulation (PWM) fan controller is used for an electronic device. The PWM fan controller includes a number of PWM signal generators, a number of PWM signal output elements, and a control unit. The control unit includes a number of outputs. An input of each PWM signal generator is electrically connected to a corresponding output of the control unit. An input of each PWM signal output element is electrically connected to an output of a corresponding PWM signal generator. An output of each PWM signal output element is electrically connected to a corresponding fan of the electronic device. The control unit is configured to control the PWM signal generators to sequentially generate a PWM signal to drive a corresponding fan to rotate in a preset time.
