ABSTRACT:
A method for detecting a power load of a power supply module, includes: receiving a pulse width modulation (PWM) signal generated by the power supply module, wherein the PWM signal is utilized for controlling a driving voltage outputted from the power supply module; detecting a duty cycle of the PWM signal; and determining the power load of the power supply module according to the duty cycle.
