Abstract
An apparatus and a method for peak shifting adjustment are disclosed. The apparatus includes a controlling unit that is configured to sequentially control different outputting units to output the Pulse-Width Modulation (PWM) signals according to a preset time sequence. The interval between two adjacent outputted PWM signals is T1, which is the time when the current required by an electric device is higher than the normal current in case of an increase of the duty cycle of the PWM signals. At least two outputting units are connected to corresponding electric devices and configured to output the PWM signals to the corresponding electric devices according to the control of the controlling unit.
