Abstract
A power supply system to provide power for a central processing unit (CPU) includes a bridge circuit, a pulse width modulation (PWM) controller and a pulse adjusting driver circuit. The bridge circuit detects a work state of the PWM controller to obtain a feedback signal output from the PWM controller, and provides the feedback signal to the CPU. The CPU outputs a control signal to the bridge circuit according to a work state of the CPU and the feedback signal, and the bridge circuit outputs a PWM signal to the pulse adjusting driver circuit according to the control signal. The pulse adjusting driver circuit receives a first driving signal provided by an external circuit, and adjusts the first driving signal according to the PWM signal to generate at least one second driving signal to drive the CPU.
