The invention discloses a control method, system and device of a multi-phase voltage regulator and a storage medium, and is applied to the technical field of power supply control, and the method comprises the steps: determining the number K of started current Phase branches according to the current load information, and carrying out the drive control of the corresponding K Phase branches through PWM drive signals 1 to K; recording the accumulated working time length of the multi-phase voltage regulator in the light load mode, when the accumulated working time length is greater than a first time length threshold value, adjusting mapping information used for representing the corresponding relationship between the PWM driving signals 1-N and the N Phase branches according to a preset rule, and resetting the accumulated working time length; wherein each Phase branch is used for controlling the working state of the Phase branch through one PWM (Pulse Width Modulation) driving signal which corresponds to the Phase
